Any comments about Amiti Free Antivirus?

Best Free Antivirus Software 5 years 1 month ago MidnightCowboy Uses Clam AV engine and signatures so detection rates will be very poor in comparison to other products. Will not be featured here. MC - Site Manager. view

Panda Cloud Antivirus changed to Panda Free Antivirus a while back.

My system:
Windows XP (SP3)
Athlon XP 3000+ CPU (w/SSE but not SSE2 or above support)

I switched to Panda Free Antivirus 15.1.0 soon after Avira Free Antivirus ended official support for Windows XP on 08 APR 2015. So far, so good ...

Panda has so little impact on my system's performance that it's almost like having no antivirus program installed at all: my computer starts quickly, programs launch/open quickly, and files open/load quickly. How well Panda is protecting my system, I haven't a clue, but it tests very well in the various antivirus tests I've seen on the Web.

I do get one ScRegSetValueExW-related 7006 error on my Event Log each session because of Panda. Panda says that the error is normal (and not a problem) because of Panda's self-protection feature: "[Panda] has a self-protection feature included and this event appears because somebody or some program is trying to modify any of our registry keys, thus we are denying the modification." It causes no slowdown or problem that I can tell, so I tend to believe them. Avira (and Avast and AVG and Comodo) cause many, many Event log errors and warnings, so I'm happy to be down to just one.

Panda is easy to install and setup and allows the user a reasonable amount of control over the settings. Big items include customizable scans, a scheduler for scans, and exclusion lists. The Update feature is automatic, and I don't believe that it can be turned off(?); there's also an on-demand "Update now" button. I'm guessing that "updates" include both virus definitions and program updates. Major features -- Real-time protection, Process Monitor, and USB Vaccine -- can be turned on and off individually, as can many smaller sub-features. The Windows 8-ish control panel GUI seems more designed for fat-fingered users of devices with touch screens than for handsome, erudite users of "classic" desktop PCs, but it's straightforward if not very elegant. Power users will no doubt want more control, but Joe Average users with slight geekish tendencies will likely be happy enough. Also, I haven't noticed any pop-up ads or anything of that sort ... only some notes/links on the control panel encouraging me to upgrade to Panda Antivirus Pro (which adds a firewall and Wi-Fi protection).

I signed up for a Panda account, but I'm not quite sure if that's required or not -- the program seemed to work fine before I signed up. Signing up requires an e-ddress and password but nothing else, though Panda does politely ask for your name, address, phone number, etc. (which I did not provide). I haven't received any junk mail from them yet.

I've tried out most of the well-regarded free antivirus programs -- AVG, Avast, BitDefender, Comodo, Panda, and one or two others -- and Panda is clearly the least performance robbing of the bunch on my ancient machine. BitDefender is quite good while it works, but it's a bit touchy and quits auto scanning after a week or so on my machine -- though it works without a hitch (and has for over a year) on my dad's newer Windows 7 machine with up-to-date (SSE2+) CPU. Avast, AVG, and Comodo slow my computer quite dramatically, with even the simplest things (opening the Start menu or Windows Explorer or Notepad) being annoyingly delayed. I suspect that my ancient CPU's lack of support for SSE2 and above may be the problem in some of these cases, as a lot of newer software works better with, or even requires, a CPU with SSE2+ support, so users with a newer CPU may not encounter these problems.

First I had AVG free when I had slow internet connection. Then Avast which consumed lot of Internet data. Then I switched to Qihoo 360 Internet Security. Recently I switched again to Baidu 'Free for ever' Antivirus. I liked this AV. Lots of features. I am interested to know why it is not included in this list here.

I am puzzled by your comment about bloatware/opencandy with Avast. I have installed it on three laptops and there's no trace of Opencandy on any of them. I have found it very easy to avoid installing Chrome if I don't want it.
I find an increasing number of nag screens in Avast, and it does try to get you to upgrade - always at an alleged discount: does anyone ever pay the so called full price?
But the free version has been very effective in blocking all sorts of invasions... so I'm relucatant to abandon it for the reasons you give.

Best Free Antivirus Software 4 years 11 months ago Paxmilitaris

I'm here right now because i have Avast and as you say i never saw any Opencandy but the attempts at tricking people into upgrading instead of updating are ridiculous.

My problem with Avast is that when ever it detects something, i can't have it ignore the "threat" even if i click the false positive link.
Because of that, i'd have to disable Avast just so i can update a portable program that it has decided is Adware.

Best Free Antivirus Software 4 years 11 months ago Paxmilitaris

So, you are a Comodo fan, but you didn't put any links to download Comodo Antivirus, your #1 recommendation.

I personally hate Comodo, ever since my brother installed their firewall on my parents' computer and i had many many many problems with it.

Panda Free Antivirus is a PUP on my Win 7 64-bit in that it keeps popping up an ad. for Panda Pro at random times and too often in the middle of something I am doing on the desktop.

> "Panda Free Antivirus is a PUP on my Win 7 64-bit in that it keeps popping up an ad. for Panda Pro at random times and too often in the middle of something I am doing on the desktop."

Then uninstall it and use something else. It is a free program. I see nothing wrong with providers of free stuff trying to get you to upgrade to something that gives them some compensation for teir work. If they do it in a way that is inttrusive to you, then just move on. Maybe buy a pay program = no ads (well, usually).

Not sure about listing MSE Microsoft Security Essentials as unsuitable or subpar.
It is true that they rank low on the test scores.
But there's an assertion that MSE focuses on the most popular exploits.
So we might have a "real-world" vs "academic" controversy here.
Ie in an academic settings (AV tests), with contrived threats, ie, including some rare ones, MSE doesnt perform well.
But in the real-world with threats that are commonly seen, it performs just as well as the others.
Ie you have no greater chance of becoming infected with MSE than with any other AV.
MSE is also free and fast, so I would not demote it.

My personal opinion, is if you take the AV Tests, and give them a good shake (ie replace the threats tested with an different but equivalent set), then everybody's going to score differently.
So my opinion pick a fast, unobtrusive one. That's MSE or BitDefender today, but every year brings a new mix.
Actually, before coming here today i would have put Panda on that list, but people here report popups.
And supplement with Malware Bytes anti-malware and Super Anti Spyware once a week.
And use Sandboxie or VMware player or VirtualBox for risky stuff.

Best Free Antivirus Software 4 years 10 months ago MidnightCowboy You make a very good point johnvk, in fact several of the people I still service use MSE and none of them are getting infected. This is because they realize an antivirus solution is only part of the strategy for staying infection free. The rest depends on the user and how they operate their system when connected to the internet. If this usage is such they think they can surf blindly into any site and install software from any source, no matter which antivirus they have, infection is a matter of when not if. Common sense together with browser add-ons such as WOT and uBlock Origin plus Sandboxie, WinPatrol Free and in my case Toolwiz Time Freeze for software testing will be perfectly adequate when used with MSE.

MoonSecure Antivirus:

Best Free Antivirus Software 4 years 10 months ago MikeR

I do wish when posters tout something on here -- as in this recent post about "Moon Secure AV" -- they'd do more than tout but instead amplify their contribution, in this instance with some reference to calibre of performance and provenance of producer. Last I heard, Moon Secure was an Indian enterprise which used ClamAV and then ceased business. That's about as staggeringly unimpressive as it gets -- so why is this particular "AV" being promoted in this comments thread? Looks like spam to me.

Avoid Avast ads/popups/craps, etc...

Latest Stable Avast Free
Win 10 64

Win FW - Go to Advanced Settings - Top left side click "Outbound Rules" - Top right side click "New Rule" - Check that "Program" is selected - Click next - Check that "This program path" is selected & paste "C:\Program Files\AVAST Software\Avast\AvastUI.exe" without quotes - Click next - Check "Block the connection" is selected - Click next - Check all the "3" options are selected - Click next - Paste "AvastUI" without quotes in the option "Name" - Click finish.

Comodo FW - Set CFW to "Custom" - There will be couple popups - Check the popups description - There will be a popup for "AvastUI" - Select 'Remember This" & click "Block" on the popup for "AvastUI".

Win FW - I am running Win FW. And have blocked "AvastUI" as mentioned above.
Everything seems fine i.e Realtime/WebShield alerts, databases/streaming updates, hardened mode alerts, etc...

Comodo FW - I had blocked "AvastUI" as mentioned above. And ads/popups were not there. Forgot to check Avast functioning as mentioned above for Win FW. I think Avast should work fine.

Note - Only thing I noticed that Avast help links from the GUI mention "You are offline". So online content is not available & only offline content is available.

It seems blocking of AvastUI.exe as mentioned above takes care of all the Avast craps i.e no ads/popups, no upgrade button on the main GUI, no ads on the main GUI, no Chrome/Toolbar offers options during install/upgrade, etc...

I uninstalled Avast Free. But didn't remove the block rule for AvastUI.exe from Win FW.
I had a previous installer so installed Avast Free. No Chrome/Toolbar offers options during install. I then upgraded to the latest version & no Chrome/Toolbar offers options during upgrade.

I've been using Bitdefender Free for about 6 months now and while I'm an advanced [cautious] user, I've had no issues with it. It took a while to get used to just leaving it alone, as in the past I'd go in and tweak all the settings of my commercial antivirus.
As the author wrote, there's no conclusive evidence that the Bitdefender Free engine is the same as the paid, but it's pretty likely. One area that the free is much better than the paid is in usage of system resources. This is likely due to all the supplemental features the paid versions have. At idle, the Free version uses about 25 MB of memory as opposed to close to 250 MB for the paid Bitdefender AV Plus 2015. Consequently, the paid Bitdefender uses as much memory as McAfee! But I digress.
My point is, the free Bitdefender is a great product for either A) a total set it and forget it user like an elderly relative; or B) a power user who has trust in the product and who'd be able to tell if something were not right on their system.

Here's the simple, layered security setup I use on my Dell (every day) laptop:
1) Bitdefender Free A/V - set & forget
2) Windows Firewall - set & f9rget
3) Mcafee Web Advisor (aka Site Advisor) - for supplemental URL blocking and search engine result ratings (Mcafee has the best product in this category IMO, by far - far better than Bitdefender "Traffic Light" )
4) Malwarebytes Free - manual scan every 2-3 weeks

I'd be very surprised if the Bitdefender paid versions used drivers as old as those.

Yeah, me three. Been using Avast for years on a number of computers and nothing extra has ever been installed by itself. The popups are slightly annoying but are occasional and no real biggie. The only thing you have to watch out for, besides the Chrome install option (and even that didn't show when I installed it yesterday via is that during upgrades it's easy to click install for the paid version.

While it's not usually THE top AV solution in the various AV comparisons, it is usually ranks near the top, and has a reasonable memory footprint.

I have been repairing computer systems since 1989 and if there is one thing I have observed, the antivirus tests run in labs are significantly different than what happens to users' computers. Basing a choice of anti-virus upon the results of lab tests shows the media wants to avoid assuming any liability - they blame it on someone else. What good is advice where no liability was assumed? There are some informed comments here and I appreciate those who offer such responses. It is obvious because they are not concerned about themselves, they express concerns for all of us. KUDOS to them.

What privacy concerns might there be with free antivirus software? What are these companies getting from me by offering their "free" services?

Best Free Antivirus Software 4 years 6 months ago George.J

Hi, am the new editor here. This article is pending a major update for the New Year, so it's not been updated yet. Chiron, our previous editor left so I've big shoes to fill in. Unlike our previous editor, my results wont be considering the accolades that antiviruses have been getting at independent lab tests because the authenticity of these tests cannot be confirmed, as they don't show you proof. So I'll be doing my own malware tests on a virtual machine to consider the overall effectiveness of antivirus software. 

That being said it's finally the users choice to choose what kind of protection that they need, because no matter what antiivrus software you use, it's a safe bet that you will be protected unless you are deliberately calling for trouble. 

Practise safe computing habits, and stay safe. 

--- George.J (Editor)

Best Free Antivirus Software 4 years 6 months ago George.J

For any software that connects to the internet (most of them do) there are privacy concerns involved. Hence each software has a privacy policy. It's a general misconception that, in return for the free products offered by developers they are selling your personal information. Most antiviruses that offers you a free product normally has a paid version, so their free version promotes their paid-for product, so that these satisfied consumers can think about buying them. 

But this is mostly not necessary for home users, because basic protection provided by freeware antivirus is well and good for them. Add together a couple of other free security products you are rock-solid. Others who doesn't offer a paid for service, has other sources of revenue.

Best Free Antivirus Software 4 years 6 months ago MidnightCowboy

So are we to assume that one or all of the independent testers are lying or their methodology is somehow irrelevant to how I use my computer?

Maybe for instance you can explain how relying on AV-Test results is bad for me or other users?

I just hope we are not going down the YouTube track of chucking a bunch of URL's at something knowing that in a few minutes they will have disappeared and then ranking product protection qualities based on their detection?

It's also worth mentioning that a stack of malware can recognize when it is being launched in a virtual environment.

Regarding Panda, could someone clarify what this means - "it will auto-quarantine files which it believes to be dangerous"
When it does that to a file that I do not want quarantined -
- do I get a 'heads up'
- and is it easy to undo the quarantine ?
I am leaning heavily towards installing it in my main PC, depending on the answer to those questions

I had used Avast for years, but it was getting a bit wearing.
I tried another one a few months back. Can't recall the name, but it is well known, and gives us 1 year free.
None of my PCs are new'ish, and are a mixture XP and W7.
I find networking somewhat painful, mainly with W7 being too 'nanny'.
When I installed that 'what was it's name' antivirus, my networking got much worse.
After I uninstalled that 'what's it's name', my networking returned to it's slight PIA state.

I am currently running with no antivirus (3 weeks), whilst deciding what to go with.
I can reasonably get way with this, by being careful in emails (I always am), and using FF with NoScript.
All those minimalistic Chrome lovers out there that do not use 'FF + Noscript' are unwise (I tempered that a lot)

Although I do not think only Panda does that, restoring automatically quarantined files is as easy as clicking on the main inteface button on the top (the whole interface looks like the new Windows start Interface with the squares) and then clicking on the Quarantine's "View Details" button. There you will see all the quarantined items and you will be able to restore them. If the folder the files were does not exist anymore, it will move them to a "Lost and found" folder. If it can find the folder, restoring them will also tell Panda the files are harmless so it will not redetect them ever as malware.

Actually you can always go in settings and switch on the option for the antivirus to first ask you before neutralizing a harmful file.

I am sorry if I made it sound confusing, but I can assure you it will take seconds for you to restore your files.

I consider Panda one of the two best lightweight Antiviruses and suggest it to people that want an antivirus with options. For friends and users that just want an antivirus that will kill anything and they will never care to change settings, I suggest Bitdefender. It will brutally quarantine anything that it believes it is harmful, be it you like it or not.

Both of them though have the option for the user to easily open the quarantine and restore the file.

Best Free Antivirus Software 4 years 6 months ago weltall

Trust online is something harder to get than it is in real life for sure. I am not paranoid myself when it comes to tests, but I never cared enough if one antivirus has 10 and the other 5 labs points. There are plenty sources that show more detailed tests, which feel more trustworthy, since there are details. Indeed though knowing what the test tool does is something that would help us, not so much understand, but see results as even more trustworthy.

For better or worse, some malware do not hide only in virtual environments, but also are able to hide in the system and stay inactive, waiting for a chance when for whatever reason the antivirus will not be active and sneak up on the user.

All antivirus tools have some misses and quite some of them have a good killing ability. I am not sure if Avira is still one of the best, but that one and Bitdefender seem to prefer to hit more false positives, so they they will miss less viruses, rather than being more lax and miss more viruses.

Of course nowadays, at least to me that I am an experienced user, antiviruses all feel the same to me. [Commercial product reference removed as per site rules]

With that said though, Antiviruses are not anymore the perfect shield. Users should definitely use a browser addon to add a first wall of protection, be it like me an adblocker or any other addon, that can block malware and afar from that use occasionally an antimalware solution.

Although this is not the "Best Free Spyware And Adware Remover" list, I wonder why in the current one tools like RKill, TDSSKiller, AdwCleaner and Junkware Removal Tool are not mentioned, at least in a "products that are worth mentioning" list.

Thanks for taking the time to respond.

Best Free Antivirus Software 4 years 6 months ago George.J
The above comment was not to say that the reports made by these labs are false, they are just unreliable. As for being authentic or not, all I can say is that One Man's Meat is Another Man's Poison. Everyone is entitled to their opinion about the tests but the more I see BitDefender and Kaspersky up at the top in the Performance section, when they are infact heavy on my hardware, leads me nowhere. Also the Real-World protection tests at labs are conducted with just 1600 samples (which any YouTube user can test with) that only represents a drop in an ocean filled in malware.  
Now coming to comparing these results, on a personal basis these tests can be judged reliable, if each independant laborotory adhered to these 3 factors: 1-having the same software configuration 2-having the same hardware configuration 3-having the same malware database. Then it makes sense to compare the tests indicating the various parameters like scan times/data rate which are influenced by hardware/software config. There are many other factors that determines the results like hardware paramters (compatibility, OS updated or not, softwares being used), disaster management (backups, virtualization), browsing habits, human factors (social engineering) and all these are pitted against the World Wide Web, a real-time library of viruses, different kinds of malware and zero day exploits. Moreoever the information about malware used in testing isn't mentioned, and hence with a reasonable expectation we can conclude that the tests are conducted on a different database with different results. I'd say to take these results with a grain of salt. 
It's likely the paperwork done by these labs can be tampered without any basis and add to that the reputation of a well known organization is also being involved. Nevertheless, in short the real-world test thats been conducted by ordinary users is considered far better because now we can see the overall strong points of the products and also the product is getting tested on a wide variety of different hardware/software/malware specifications. None of the Big shots like Kaspersky, BitDefender, Avira and others might be coincidentally consistent at the top due to these common tests at the labs, but who knows?
Which leads us to this, whether it be the independant tests or the standard video reviwes at Youtube, both should be taken with a grain of salt. Simply because every product has different technologies to capture malware, having a good detection in one test, doesn't mean it is great, because there are so many samples out there and with many more coming in a daily basis it's impossible to detect them all. IF one vendor comes first, the others who didn't might detect samples that the winner doesn't have in its database. 
If anyone wishes to test a security product it's important to know how different features works and start from there, leading up to the advantages and disadvantages. If Comodo may focus on behavioural analysis, ESET might focus on static (detect prior to execution) analysis. Now this if not taken into account in a proper way, it will simply make a product look bad when it's not, if it's actual strength is used as an advantage. Someone tests a security product and concludes that it's good in protecting the system. When an independant lab does this the results might be the opposite. Now we've the same statement being used in both ways. None of these tests will show if a product is really good or bad, cauz individual products react differently in different situations and across various samples. 
To conclude, the best way I can find is to test out different antivirus and finally decide which one is that you're most comfortable using. However we see it, no matter whoever these lab tests promote as winners, it doesn't mean they are the best- the real truth is that there is none.  We as an independant review site have our own ways to test our products, and not being influenced by the outside world. I rest my case. 
Best Free Antivirus Software 4 years 6 months ago MidnightCowboy OK, so let's take the "opinion" part out of the equation otherwise we'll also end up disputing the news value of CNN v Fox but what about my question regarding testing in a virtual environment as opposed to a live machine connected to the real world internet? MC - Site Manager. view
Best Free Antivirus Software 4 years 6 months ago George.J
I agree that there have been various bugs that malware could manipulate to bypass virtual machines, but this least worries me in standard malware databases. I feel this is more on a corporate level probably, as a lot of game servers are run inside of virtual machines in large quantity. Now, if malware could be custom-designed to bypass lets say a VMware virtual machine on a Windows/Linux server, or possibly even Virtual Box on a Solaris and other systems but I doubt that would be the case. 
From the way I see it, there is a pyramid. This one goes from government made and developed malware and techniques down to consumer level. Business, Corporate etc. are in between. Business as in companies like the now extinct Blackhole create exploits and the various new ones that I don't really pay much attention to. 
I guess if you were downloading a fake crack over p2p sites, then that's actually calling for trouble and having a higher chance of being something dangerous than on a malware database, that's my opinion at least. 
My technical knowledge might be limited to understand the deeper aspects of all questions and finding answers to them, all I can do is a give an unbiased review and learn something new along the way.

AV-Test is not very good, they don't do much testing or use many samples and only score out of 6, they don't offer reports or show you their testing methods.

AVB100 only tests for the most common 100 viruses in the wild (WITH NO FALSE POSITIVES) and believe me i would rather be told and find out myself if its fake than them one slip through.

AV-Comparatives is a whole kettle of fish, they are certified by ISO and EICAR (others aren't) that their test procedures are solid, they also write up multiple page reports on the tests, perform many tests in comparison to the others and also score properly aswell as doing lots of various testing using 100,000-200,000 infections per test (for File Detection Tests) then you have Real World Tests, Heuristics Tests, False Alarms Tests, Performance Tests, Malware Removal Tests, Anti-Phishing Tests, Parental Control Tests, Mac Security Reviews, Firewall Reviews, Linux Security Reviews, Mobile Security Reviews, Business Security reviews -> where else do you get all this in multi-paged PDF reports that also show their testing procedures.

as it stands the best Free Security in my opinion is Avira (FREE) along with Comodo Firewall (FREE) and WinPatrol (FREE) - nothings going to get past that lot...Avira may not have much too look at and its a shame that it gets 3/5 on here as its about protecting your so Avast looks pretty and has extra options, but it doesn't protect your PC more than Avira - Avira has constantly been top for the past year or 2 for detection, real world protection, performance and False Positives.

Many people would never consider Qihoo for fear of a Chinese government-mandated backdoor. True, this is speculation, but it does seem worth mentioning.

I definitely had obtained it from the official source. the uninstall appeared successful but left running processes behind. Your experience may vary.
My experience and the fact that it is installed by other malware for some people is enough for me to never go back.

Wrapped installers are not the same as malware installing in the background. Google Chrome doesn't claim to be an antivirus program.

Best Free Antivirus Software 4 years 3 months ago MidnightCowboy But you provide no details of what this "malware" is, where it might be obtained from, links to any of the "multiple sites" telling how to remove it, which processes were left running after the uninstall process on your system, in fact no concrete details about anything.

You yourself posted a link of someone else who had it installed on their computer without their knowledge. A simple google search brings up multiple sites with similar stories and removal instructions. As for the processes left running, should I really be expected to remember the specific details from something multiple months ago?

amazing that I appear to be getting attacked just for relating my experience.

Best Free Antivirus Software 4 years 3 months ago MidnightCowboy

No one is being attacked here. If you search the various posts accurately you will see that this arrived as part of a bundled package so it did not get installed without user permission, rather, as is often the case, they just clicked yes, yes to everything during the installation of the other software and did not read the EULA beforehand. The fact some of the software bundles are from less than reputable sources is the reason why this became flagged as a PUP (potentially unwanted program) although both the software and the vendor are reputable enough. It is also worth mentioning that many of the "removal guides" for various software are themselves bogus such as these two (WOT (Web Of Trust) ratings links provided as the sites themselves are red rated). SpyHunter in particular is an infamous rogue and there are links to this all over the internet. As soon as one link goes red they set up a new domain. MC - Site Manager.

Your "download" button for Comodo is actually the link to Avira.

now use both it and MSE and find they work seamlessly together.
I also like the Optimise Option on 360

360 Total Security should be changed to "Free for private use only". Its website at, under Category>Others, states "The software is not licensed for any commercial business activities, profit-based business activities, or revenue-generating business activities." (Their wording is a bit unclear though.)

Best Free Antivirus Software 4 years 3 months ago sb1023

I ran 360 for about a year but got tired of the same annoying issues all the time. It'd get warning pop up about stuff that I'd already white-listed and despite continually saying "yes" over and over again I'd still get the pop-ups. Not to mention that the false positives are just excessive. They are all from the 360 engine, which is always on. It can't be disabled even if you have the other two engines enabled. If you could run it with just the Avast and Bitdefender engines it would be great.

I switched to something that only gets a nod in the honorable mentions here - Sophos. You essentially get their corporate product, complete with cloud-based management, for free for up to 10 computers.

How can one trust a company that has found to be cheating by three of the widely respected anti-virus testing companies - AV Test, AV-Comparatives and Virus Bulletin to the extent that all three testers have stripped Qihoo 360 Total Security of their test results.

Best Free Antivirus Software 4 years 3 months ago MidnightCowboy

You can make what you will of the reasons given for the test submissions (Chinese v external market) but ultimately the true detection performance is a matter of configuration.

"Investigations by the three labs found that all products submitted for testing by Qihoo had one of the product's four available engines, provided by Bitdefender, enabled by default, while a second, Qihoo's own QVM engine, was never enabled. This included versions posted to ostensibly public sections of the company’s websites.

By contrast, as far as can be determined, all versions made generally available to users in Qihoo's main market regions had the Bitdefender engine disabled and the QVM engine active. According to all test data this would provide a considerably lower level of protection and a higher likelihood of false positives. Options are provided in the product to adjust these settings, but as the majority of users leave settings unchanged, most tests insist on using the default product settings to best represent real‐world usage."

Maybe most users do leave their settings at default in which case the test results were certainly erroneous. On the other hand, using security apps at default settings quite often yields unsatisfactory results and this is not how Windows security should be configured. MC - Site Manager.

Best Free Antivirus Software 4 years 3 months ago George.J

From the comments what I can understand is that certain people have been tricked into installing a rogue software that masked itself as 360 Total Security. There could also be programs that promote 360 TS and bundle their product with the antivirus software which may or may not be fake. Same is the case with many programs endorsing Google Chrome.

Now the end user is responsible in both these cases if 360 TS (fake/not) appears on their system in this fashion. The solution to this is to download programs from their official website unless specifically stated at Gizmo's Freeware with links to alternate sites.

Until last February I used to have 360 TS (before switching to Windows Defender) downloaded and updated on one of my systems through every iteration from version 5 and I have not experienced any problems like you've mentioned. To confirm that I downloaded 360 TS again day before yesterday, and had the same experience. It had the fastest install/uninstall times among it's counterparts, completely uninstalled itself without any "parts/modules" left behind, had no so called "processes" related to 360 TS running in the foreground/background after un-installation and reboot.

About the files left behind, after un-installing an antivirus you are supposed to reboot your system before the files are removed completely, which is why you might have seen folders of files related to it left behind. Even after reboot there might be certain empty folders left behind and some with files of few Kb's which does not affect system performance. This is true for any antivirus out there.

In the case of 360 TS the folders left behind after reboot were:-

  • 360 - C:\Program Files (x86)
  • 360 Quarant - C:\ProgramData
  • 360safe - C:\Windows\SysWOW64\config\systemprofile\AppData\Roaming\360safe 
  • 360Disabled - C:\Windows\Tasks

The same is the case with Avast::-

  • Avast Software - C:\ProgramData\AVAST Software
  • avast Antivirus! - C:\Program Files\Common Files\AV
  • Avast - C:\ProgramData\AVAST Software\Persistent Data
  • Avast Software - C:\Windows\System32\Tasks

This can be replicated for others too.

You had mentioned that 360TS had been installed by "malware" [from the very little information provided by you] which caused the after-effects so the original program is not the one at fault. The software from the official site doesn't include any adware/malware like you say, and this has been confirmed prior to writing this review. If you have any doubts about the same, and willing to trust Gizmo's Freeware for our reviews, you should try it yourself based on the recommendation before following up to what others have to say.

Best Free Antivirus Software 4 years 3 months ago quasigizmodogo

I'm not sure how much I trust Qihoo and their products after reading how easily they got duped into whitelisting malware ( Not only that, but the article goes on to point out that "Testing bodies AV Comparatives, AV-TEST and Virus Bulletin decided to revoke all certifications and rankings awarded to Qihoo 360 products last year after they found that the products submitted for testing behaved differently from ones offered to customers."

Best Free Antivirus Software 4 years 3 months ago George.J

SecureAPlus is considered to be a companion AV (an AV used for second opinion apart from your primary antivirus). It's mainly an application whitelisting (trusted) software that uses a block-first approach, where system is locked down after it's install and anything that's newly installed is considered untrusted/blocked unless you allow it or is available in their continuously updated list of trusted applications.

It also has AV scanning modules with it's engines available across the cloud that will block anything that has been detected as malicious. But from the FAQ ( it appears to be free only for a year, and then it can be extended only by adding referrals.

Best Free Antivirus Software 4 years 3 months ago George.J

"Better" is mostly a subjective word. Like I already said in the Introduction part there is no Best Free Antivirus so I went through the Pro n Con structured layout in this article to make it easier for you to find an antivirus that best suits your needs.

The best thing you can do is to stick with your current antivirus, most preferably one among these mentioned in the article, while also reading through other alternatives if any particular feature in an antivirus attracts you. Otherwise you can try all of them, and stick with one. This is the best part of any software that's been offered for free.

Best Free Antivirus Software 4 years 3 months ago freestuffrocks

Qihoo 360 Total Security light? Not here. RAM usage for all processes averages around 70MB (balanced mode, without Avira and Bitdefender engines) compared with around 15MB for my previous AV, Panda Free. 360 TS is far too bloated. Also, less experienced users need to be very wary of what's being deleted/changed if they use any of the optimization tools. Certainly not recommended by me.

Best Free Antivirus Software 4 years 2 months ago George.J

It's important to note that idle RAM usage is not the only parameter to check if a software is light or not. How an antivirus affects application launches, installing/uninstalling softwares, boot time, archiving and extracting, file copying, downloading from web browsers, processor and ram usage when idle and during scans/updates along with various other factors determine the performance impact of an antivirus.

On a lighter note, Qihoo 360 usually took only around 30MB for me on idle without additional engines. What we can infer from this is that system configuration also plays an important role on the same. Additionally using any optimization software involves some knowledge about the same, but Qihoo's own tools are pretty safe to use and doesn't involve registry cleaning or advanced optimization techniques. But I wouldn't still recommend 360 TSE (Essentials) over 360 TS because it has slower updates and sometimes more false positives for some reason.

Best Free Antivirus Software 4 years 2 months ago freestuffrocks

Thanks for the quick reply. Reading other glowing reviews and user experiences of 360 TS it does seem I'm in the minority regarding RAM usage. I was wondering if there was a conflict with Zemana AntiLogger Free as 360 TS also has an anti keylogger component but disabling ZAL made very little difference. I'll persevere with 360 TS though because fundamentally it seems pretty good.

Best Free Antivirus Software 4 years 2 months ago Remah 360TS uses 70MB on my system with Avira and Bitdefender engines enabled. view
Best Free Antivirus Software 4 years 2 months ago George.J

I didn't have a problem with the same application after white-listing it. Since Qihoo has high proactive (behavioral/heuristic/hips) detection capabilities it might show false positives for certain files. Most of which I have seen is from various C++ and Java programs that I have written, and since there is code injection involved it detects as heuristic (possible) malware. But it still doesn't delete those files, but is left upon to user's choice to analyse and determine which files to keep/remove.

The notifications that you might have received and answered "Yes" to might be when an application was trying to access protected areas of the registry. Qihoo has registry protection feature where important areas of registry are being monitored. So those pop-up's you receive might be for individual registry entries related to a specific application. But when you click "Allow all" instead of "Allow" will give access for that software to all related registry areas instead of having to click Yes separately for individual entries. But this does not mean it "white-lists" the software during real-time/on-demand scan. You might have to manually do that by going to Virus scan->Trust List->add related .exe files.

Regarding Sophos, it's good but quite simple for my tastes. For a cloud antivirus it's not light, the install takes more than 900MB disk space (Program Data+Program Files folders) and also has high RAM usage (>200MB). Also the dashboard (controls) are present in a web-like interface accessed through a browser! As for the good parts if you have multiple systems to manage it's sweet. Also it's web protection is great, parental controls are charming with good PUP detection as well as no adware present in it.

Best Free Antivirus Software 4 years 2 months ago CASD

How do you turn them on ?

Best Free Antivirus Software 4 years 2 months ago George.J Thanks for posting the article as well as bringing that to my attention. Qihoo should have double checked the products before whitelisting them. About the revoking of certifications, that's definitely between them and the testing bodies. But when Qihoo 360 TS already does splendidly well with the default configuration that I tested (rather than the modified version submitted to testing bodies) there's little for me to complain about here. But like MC has mentioned before, using software's in their default configuration is unacceptable unless you want to go through the "easy" route. Many users customize the product according to their tastes and hence the level of protection/usability/performance varies according to each configuration. Hence testing products in their default configuration is not exactly the right way to do. It just seems simpler. view
Best Free Antivirus Software 4 years 2 months ago George.J

Click on the Protection tab in the Left side bar of the UI and then click on Custom settings. Scroll down and enable any of the engines you like and press OK. Now go to Virus scan tab in the left side bar, and then on the bottom move the slider bar to green over the Avira/Bitdefender engines.

If it was me I would enable them only during on-demand scans, and disable it in real-time.

I find it my self very similar as you described in your reviews. 360 is the best, Comodo has improved a lot in the last years, Avira always been good. But I find it confusing why Quihoo's 360 is not represented in the big AV-Comparatives? Neither Comodo... I recommend you one more antivirus to review: Sophos Home. Is the third biggest security company on the world (behind Norton and Kaspersky), light on resources (cloud), very simple to use and in quite a few tests (Scanning speed, resource management, total hits, etc...) is in the top of the AV softwares.

Best Free Antivirus Software 3 years 9 months ago cavehomme

I've tried Sophos Home recently and I am not yet convinced of using it beyond my tests. Detection can be very good but on AV Comparatives it's overall real world detection is similar to Windows Defender, sometimes worse! For resources, on my PC it has 6-8 various components which when idle total around 300mB of RAM, that's a lot and although I have 8GB RAM the PC feels a bit sluggish especially when browsing. It's also a pain having to go into the online control panel to add exceptions and other tasks rather than doing it immediately and smoothly in the client software.

Also re-tried Avira recently. I found it's heuristics to be really excellent, unlike the review above, especially on identifying macro viruses and trojan downloaders which then download Locky and other ransomewhere. In my tests Avira detected all zero day stuff that had just arrived in my mailbox and this was confirmed as brand new on Virustotal and with Avra being in the first bunch of 7-10 detectors out of 55 that quickly, even immediately detected these things. On the downside, once detected, cleanup is very slow which would not be a problem but it leaves lots of remnant files and folders which is confusing and makes the user think that the malware is still there. Also the interface is not only very old but also quite confusing. The seperate program / process of Luke Filewalker is just plain ridiculous in my view, it should be integrated fully and seamless.

Tried most others but currently still on Windows Defender because it has the least impact and the best cleanup but detection although much improved this year needs to be a lot higher.

The latest beta of free Bitdefender looks promising but whilst it remains a beta I won't be trying it.

For Windows 10 users the latest Bitdefender Free AV coupled with their stand alone BD Anti-Ransomware which is also free offers excellent protection.

360 Total Security is a decent program although too bloated for my tastes like most of the leading commercial programs.
I prefer Bitdefender AV 2017 Free in conjunction with their separate free Anti-ransomware app.
Industry leading protection in all independent testing and very light on resources.
Very minimalist interface with virtually no input required from the user plus it was rated by the CIA's hackers as the most difficult AV to penetrate (in fact they could not hack computers protected by BD according to the Wikileaks recent release of internal CIA secret documents) and the free version uses the same scan engine and technology as their paid versions according to tests done by Neil Rubenking.
Most of the free AV program available these days are good and I guess it is more a question of meeting the needs and expectations of individual users.

Actually I am also very much eager to use Bitdefender Free Antivirus on my computer.
The only thing keeping me away from using this antivirus is that I will have to uninstall my existing antivirus which I do not want to do.
I am proud to tell everyone that traditionally I have been a long term user of Bitdefender free antivirus (during its previous years). I dropped it because of compatibility issues with windows 10. But now the picture has changed. In those days I felt sad that no one seemed to recognise such a great antivirus. It was highly underrated But hopefully now the things are turning in its favour.

Download its free antivirus which works on autopilot along with its small anti-ransomware software and you are good to go. As a matter of fact it provides most power protection against phishing also by directly scanning all http traffic. And all this for a free product where paid ones fail to match even the inbuilt protection of most popular browsers. Its zero day protection is also best in class.

Also it is worth mentioning that 360 total security lies at the opposite pole when compared to Bitdefender free antivirus. How............................

1.) 360 Total Security requires lots and lots of user input due to highly aggressive heuristics ( with all its features it is certainly a tool for experts ) while Bitdefender free antivirus uses highly advance detection techniques like "B-HAVE" (more on it later) and works without much user input.
