Best Free Antivirus Software 6 years 2 weeks ago George.J Thanks but Avast faired poorly in file detection mainly because of the 140 false positives!! :| Anyway these results change from time to time. view
Best Free Antivirus Software 6 years 2 weeks ago Chiron I have thought about including False Positive information, but still have to find some tests which I believe are decidedly real-world enough in terms of how likely users are to actually run across false positives of the type they are being tested against. I will look into including information like this in the next rewrite, assuming I can find some tests I am happy with. Thank you. view

I thought you should know that it has gone worse, now Comodo SecureDNS completely blocks access to Qihoo's English website: http://www.360safe.com

It's worth noting that this didn't happen before, it was only blocking the download.

Best Free Antivirus Software 6 years 2 weeks ago Chiron Thank you for keeping me up-to-date. I have been keeping an eye on it, and I believe the number of false positives it gives is too large. I have therefore updated my information for this article. I now recommend that users untick the option to Enable Comodo Secure DNS during installation.

If I may put my two cents in, Bitdefender free edition is not a good choice.

You have to download an installer -an offline intaller simply does no exist- and the installation needs several consecutive downloads even after the installation. The first definitions update takes a while and sometimes goes wrong, so the program forces you to start the updating process again. I know this because I tried installing bitdefender on different PCs from friends and relatives, so I can say the process isn't as smooth as you'd want.

The installer does not include an uninstaller, you have to download a third party one if you ever get bored (or annoyed) by Bitdefender. Also, you have 30 days to test the product, after that period you are forced you to create a free BitDefender account or login with facebook or G+ within the app to continue using the product.

IMHO, not the best of approaches.

I tried the latest version of Avast! (Avast 2015), and didn't like it: it is heavy and cluttered with useless stuff, it's an antivirus that tries to be cool and fashionable with social features, badges, prizes, karma and Facebook, which is not what I need from an antivirus.
At some point my computer was almost stuck: one of the Avast files was using 200+ MB of RAM and growing, and it was using at least 20% of the CPU resoruces, not sure for what reason, because couldn't tell from the user interface and it was unclear how to stop whatever it was doing. It's the kind of situation that makes me remove a software right away, because I don't like when a software does not show clearly what it is doing and ruins the performance of a computer.
Currently I removed Avast and I'm trying Panda (v. 15.0.3).

Best Free Antivirus Software 6 years 2 days ago limmy25

I have to agree, the new Avast! looks great and all but it just became the new AVG but its resource usage is better than AVG

The process that was causing that usage was probably the new Avast! NG. You can read about it here, http://malwaretips.com/threads/avast-ng-what-is-it-avast-2015.35640/

Its sounds good but it takes up to 2GB of my HDD space, I'm also currently trying Panda

Personally I don't use any AV on all of my machines recently and I feel pretty comfortable! No single issue for a very long period of time. As I have said many times - the use of AV software is too much overrated nowadays, especially if you are an experienced user. Moreover (just like with the cars) - I'm a big fan of performance, not of the security. There's not such a thing like "AV light on resources" - they all have impact on your system, always!...

Cheers everybody! :-D

Best Free Antivirus Software 5 years 12 months ago Anupam While you as an experienced user may not need an antivirus, general users still need one. Security is important for them. view
Best Free Antivirus Software 5 years 12 months ago Chiron Personally, although a small subset of users may not feel that an antivirus is suitable for them, I do believe that an antivirus still has a significant role to play in terms of protecting a computer.

There are some AV light on resources; I'm using Panda free Antivirus and I'm impressed by its very low usage of RAM and CPU. In this moment this is the RAM used by Panda on my PC:

Best Free Antivirus Software 5 years 11 months ago Anupam Chiron, I installed Comodo Antivirus on my laptop with Windows 7. I plugged in a pen drive containing my software collection. Comodo detected some files as suspicious. I chose the option to ignore and add to exclusions, but this does not seem to work. Even choosing ignore once did not seem to work. It just kept on popping until I chose the option to either quarantine the file, or report it as false positive. How do I solve this problem? It's quite annoying. view
Best Free Antivirus Software 5 years 11 months ago George.J It actually depends on your system resources. If you're having enough resources, you won't find any lag. Moreover I believe what you posted here is the idle RAM usage. Try starting a scan, or opening documents, installing executables, copying files, browsing internet, CPU usage etc that can also include in resource consumption. view
Best Free Antivirus Software 5 years 11 months ago Chiron Sadly, this sounds like a bug to me. I do know that ignore once does not work correctly (even though it was reported long ago by me). However, I was not aware that exclusions does not work correctly for removable drives (which is what this sounds like). If you are able, it would be very helpful if you could make a bug report for this on the Comodo forums. However, as a workaround, I would say that if reporting it as a false positive allowed it to work correctly, perhaps that is the best option for the time being. Thank you. view
Best Free Antivirus Software 5 years 11 months ago Chiron I'm sorry, I just noticed this reply. As far as I know Avast is the only one in this list which requires registration. However, please note that I have not tried out all of these on my system, and thus cannot be entirely sure. If you find that any of the other programs in this article do require registration please let me know and I will include that information in the article. Thank you. view
Best Free Antivirus Software 5 years 11 months ago Chiron Thank you for letting me know of your experiences with this product. I will keep this in mind. Also, what are others experiences with this product. Have you run into as many problems with it as UserError? Thanks. view
Best Free Antivirus Software 5 years 11 months ago Anupam Agreed with the points. For the same reason, I was not able to install this antivirus on an old computer which is not connected to the internet. I was looking for a lightweight antivirus, and I thought BDAV free would be a good choice. But, lack of offline installer, and creating a free account was what put me off. Even if offline registration was possible with it, like Avast has, I would have given it a try, after connecting the PC to internet for a while. But, given the present situation, gave it a miss. With lack of customization, and these issues, they are really making it hard on themselves for users to be able to accept this. view
Best Free Antivirus Software 5 years 11 months ago Anupam I too had the same thought, that this might be a bug related to the file being on a flash drive. I don't think I will be posting about it on the Comodo forum, as I do not intend to use the software for long. Strange that not anyone else has found out about this bug yet. view
Best Free Antivirus Software 5 years 11 months ago bili_39

Most of antivirus programs have this problem (well, I know for Bitdefender and I think Symantec also). My workaround is to temp. disable on access protection.

Exclusion would not be very smart option with removable drive, IMO.

I tried 360 for the first time this week, and I'm really liking it.

Unusually for a "suite" I'm actually finding all of the different modules useful as well.

It took me a little while to realise that activating the Avira and Bitdefender modules seems to be a two-step process. I ticked boxes that I thought had activated them and only later found other activation switches in the actual scan dialogue.

It is a little bit buggy I think ... some of the pop-up notices appear a bit erratic as to whether they decide to show themselves or not and it also seems to fall prey to the common W7 issue of disappearing systray icons. Installing it into a clean W7 seems to have helped with that though for now.

Some of it is a little confusing to a first-time user ... for instance I ran the Cleanup module which broke ClassicShell for me, until I realised that it had quarantined the toolbar components of ClassicShell.

All in all I like it a lot though, especially the alternative Windows updater. It seems to run happily with Comodo Firewall too and performance is still good even on my elderly 2Ghz/2Gb desktop machine.

By the way Chiron, your Dennis Technology link goes to the 2013 test results.

Thanks for a great article anyway. I've been using Comodo CIS for a couple of years or so now but I was finding that the AV component was a bit demanding on my low-end hardware, so this week I've tried out most of the alternatives on this page.

Panda I liked quite a lot ... I've used their portable on-demand scanner for a while now so I thought their free AV would probably be pretty good. Which it is, although for me it lacked some configurability and I didn't really like the auto-quarantine behaviour either. I tried 360 just out of interest really but I think I'll stick with it for a while. I seem to recall some concern about their privacy practises a while back but I've not heard that mentioned since.

I noticed this week that none of these AVs seem to flag the Nirsoft suite as malware ... I don't know if this is due to Nirsoft finally getting the message through, or some other factor such as heuristic scanning.

I'll still be using Emsisoft and MBAM as on-demand scanners as these two between them seem to pick up everything.

I see by the by the way that Comodo has received its first update in some time. I really happy to find that the awful process of unblocking blocked executables and adding them to the trusted list has been changed and is much easier now. But again, a bit erratic ... some blocked files can now be trusted via a small screen pop-up, while others still require the tedious process of opening the main program and adding to trusted, etc etc. I noticed also that some execs continue to run even though they get added to the "unknown" list and I have everything set to "block".

I see the settings dialogue has changed too though, so maybe there's something there which might explain that.

One of the things I love about this site is that the reviews are always reviewed, meaning that when things change, you often update the best-of lists. And the comments are often very helpful.

Just out of curiosity, though, wasn't Microsoft Security Essentials top rated a while back? O_O But now it's off the list and just mentioned as sub-par? OHMY! What happened?

Also, an update of Avast gave be blue screens of death, and when I uninstalled it and tried to go to Comodo, it said I already had it and couldn't upgrade directly. I'm thinking it's because I have the firewall version. I reinstalled Avast but chose the minimal bells and whistles. So far - so good, but I'm thinking of uninstalling the Comodo firewall and trying Comodo anti-virus again.

Anyway, again what happened to MS Essentials?

Best Free Antivirus Software 5 years 10 months ago biggerabalone

it may not be a false positive. there are many corporations (one of which i worked for) that have proprietary secrets and/or negotiations ongoing for business deals. our servers were repeatedly hacked by hackers located in china. how they accessed our systems led to the banning of communist/state owned/chinese software for all employees in sensitive areas. i guess it make sense(?), i doubt the u.s. military used soviet cloud based antivirus software to secure their systems during the cold war, lol. perhaps comodo is aware of this building tension/caution within governmental and business environments.

Best Free Antivirus Software 5 years 10 months ago freestuffrocks

Reluctantly I've just abandoned Comodo AV after yet another nightmare install attempt (in fact, many attempts!). Version 7 worked fine but version 8 wont install despite following Chiron's clean install guide on the Comodo forums to the letter - Comodo keeps on saying it can't load because Avast is incompatible despite me looking everywhere and, as far as I know, removing everything to do with Avast. I also used the firewall part of CIS and I particularly liked the way you could bind applications with Comodo, for instance, to a VPN to safeguard against disconnects.

Anyway I've switched to Panda free AV and working nicely - never used it before and wasn't aware of its excellent performance in recent AV tests.

I have been using avira for ages but recently they have overdone it with the offer pop-ups. I tried comodo but you have to teach it everything from scratch. So I'm thinking to try panda but I also don't like much automation (I know! I'm hard to satisfy). Actually I find avira fine in configuring and automation. Can anybody please tell me whether panda is more automated than avira? I mean I would like my AV to ask me of what to do when something is detected. Can this be configured in panda?

Best Free Antivirus Software 5 years 9 months ago GJW

I am not very familiar with Panda. Just a tip: you can disable the offer pop-ups by making a blocking rule in Windows firewall for Avira file ipmgui.exe.

view
Best Free Antivirus Software 5 years 9 months ago MidnightCowboy Your comments, especially regarding Comodo, suggest a confusion between the normal antivirus and HIPS functions (where included) of security programs. IMO if someone is capable of determining the correct actions to take for every event, then a correctly configured standalone HIPS such as Malware Defender could be used instead of an antivirus program. In reality though a broad spectrum antimalware solution containing multiple detection methods will always be the preferred solution although this inevitably involves a degree of automation. Panda scores highly with both AV Test and the AV Comparatives Real-World Protection tests. Yes it is more automated than some but IMO this is how it should be, especially for normal home users many of whom will not have the knowledge, or desire, to operate their security programs manually. MC - Site Manager. view
Best Free Antivirus Software 5 years 9 months ago lascetic

The thing with comodo is that if I disable HIPS and sandbox the windows action center gives me a warning that no antispyware program is active but only antivirus.
I don't want to disable WAC, but I find HIPS and sandbox personally annoying and not very useful to me (the way I use my pc). With avira I had antivirus and antispyware all in one, running smoothly with only the necessary to me alerts. So I was wondering if Panda is similar to avira in that sense. It worries me that this article says that in auto quarantines items that finds them suspicious. That is because I have used other AV software in the past that have quarantined or deleted items without a warning and it was very difficult to restore them cause it would immediately put them back to quarantine and they were not very configurable. So before I install panda I'm trying to get some more information on whether it has this kind of behavior. Thank you for the advice.

I dumped AVAST, as it insists on installing Chrome, V10 has lots of problems, lots of ads, even in the Pro version, which to me is unacceptable.

In my search for a replacement, I chose Panda Free. Works great, has great detection rates from all agencies, is clean and simple. You can turn off the "news feed", auto-quarantining, etc in the settings.

You can have it ask what to do if a virus is found.

There aren't as many settings as AVAST, but all the basics are covered in a very logical layout.

I'm running it on Win 7 Pro x64, Win 8.1 computers.

There were lots of problems reported with Avast ads and automatic installs of Chrome but as far as I know this related to the paid version only. There is no "DNS Shield" but there is "Secure DNS". Avast uses the word "shield" for several of its other features including "web shield" and "mail shield" so the poster might have misnamed it. view

To All,

I apologize for including comments about the paid Pro version of AVAST. Please edit as needed.

I have both installed, Avast free at home and Pro at work and got them intertwined in my post.

I have never has issues with Open Candy and the free version using the Software Updater. In fact, that is a great feature of Avast, one that I would miss if I switch to Panda.

It is not DNS Shield, it is Secure DNS and is only in paid versions.

Avast will default to checking the Chrome installer on every update.

It displays ads in the status screen.

This is not false information!!

Might do well to remove Panda AV altogether from the list.

The differences between them might alter every time a new program update is issued.

It also depends on whether you use all of the offered components, I don't.

Last time I checked, BitDefender Free had the lowest usage but it was also the least configurable. My choice is a custom install of Avast Free, I just select the parts I need and then configure it to my needs.

About two months ago, I had to wipe my computer and reset to factory specs, after a virus-related issue I just couldn't get rid of. (Happens about once a year for me. Means I'd like to see the death penalty for all virus writers.)

For the last two months I have been letting the built in trial version of one of the companies that doesn't have a free virus option cover my system, while backing it up with Spybot (for the immunization protection), Ad-Aware (just because it has been one of my back-up options for ages) and MalwareBytes because it cleans up almost anything.

Today, the trial software (which still had four days left) turned itself off, and turned off my firewall, too. I did scans with all four products, none finding anything, removed the trial virus program, and installed BitDefender as my 'active' program, with the other three still being regularly used manually to scan for problems.

Considering adding Avira as just another 'try it once a week or so, looking for any problems.'

Since MalwareBytes is almost always my first thing to throw at anything that acts weird, most of the others never get a chance to find anything, but I still lake the extra options to try and make sure everything is good.

Any thoughts or comments?

view
Best Free Antivirus Software 5 years 6 months ago MidnightCowboy It is never advisable to install more than one antivirus program. There are umpteen posts from reputed sources on the web about this, these being just a few. http://www.pcworld.com/article/2034141/one-antivirus-program-is-better-t... http://www.computerhope.com/issues/ch001136.htm http://blogs.microsoft.com/cybertrust/2014/08/05/can-i-run-more-than-one... Secondary scanners that are designed for this purpose are fine, but there are also risks associated with installing a second real-time product and then disabling the active protection. In any case, it is always better to prevent infection rather than trying to clean up after one. The best strategy therefore is to understand how and where from you became infected previously and then tailor your PC usage to avoid further repetition. Having 10 scanners on board still won't help if there is an underlying usage trend to become infected. You might find these articles of interest.

I recently dumped Avast after many years simply because of the annoying advertising pop-ups. After reading the recommendations by Chiron for Comodo, I installed it and have had it running for a few days now. No problems with it except for the deceiving tactics by Comodo during the install process.
Despite selecting "custom install" and unchecking the boxes that I didn't want, Comodo ignored that and installed everything.... I had to manually get rid of geek buddy and the Comodo browser.
How can this forum recommend software that continually breaks the rules ?

Best Free Antivirus Software 5 years 6 months ago MidnightCowboy I downloaded the installer today from the link on our page. The file was: cav_installer_3272_7b.exe (204.1 MB). I selected the language and unticked the options for cloud based behavioural analysis and anonymous usage statistics. I then chose "customize installation" and unticked the options for GeekBuddy and the Comodo browser (Comodo Dragon was already installed on my system which is why it appears in the program list) Proceeding with the installation I also unchecked the options for using Comodo DNS and the search engine change. The result was a clean install with nothing else added or changed. http://i.imgur.com/1meMBnK.png If you research this properly you will find that GeekBuddy can also be included with a third party wrapped installer, so if you obtain the program from a different source, it is still possible for this to be installed even though this option in the Comodo install process was denied.

I think here is three of the best free antivirus software for multi-platform, including Windows, Mac OS X, Android and iOS.

- Avast
- AVG
- Avira

Best Free Antivirus Software 5 years 6 months ago Anupam Were you that annoyed with the pop-ups? I have Avast on my system, and I think the pop-ups occur only when the definitions are updated. Although their size has increased, still, I do not find them annoying. It's something I can do with, considering the fact that the antivirus is great, and free. view
Best Free Antivirus Software 5 years 6 months ago terrawarra

G'day Anupam,

When I first installed Avast about 3 years ago, everything was good.... it was quite unobtrusive and yet quick to strike on any bad guys.

In the past year or so, with the regular updates from Avast, it seems to have become bloated and whilst I was still very happy with the protection it provided, it did become intrusive , the constant pop ups telling me that there were X amount of problems/issues with my PC seemed like a ploy offered by many shonky software programs that diagnose your PC, find many problems and then offer to fix them for a fee of course !
The Avast pop up invited me to click on a button to fix the issues with my PC and instantly I was greeted with a new message advising me that it would cost for the premium features to carry out this task.
Doesn't matter how many times I declined, the pop ups kept coming.
Bottom line ?..... yes, the pop ups did start to annoy me.
I know that Gizmos site does not endorse any paid-for commercial product and I believe that the free version of Avast is pushing the boundaries here with its constant nagging to upgrade to the premium version.
Meanwhile, I have Bitdefender free version running..... it's so unobtrusive and sometimes I wonder if it's doing anything but it has detected and quarantined 6 items since I installed it about a week ago. The only thing missing from it is email scanning but that doesn't bother me.

I dont' use Avast anymore but while I used it in the past, I don't think I had the pop-up troubles that you experience. The way you say it, it's what I feel about Avira in the past, but Avira has stopped with it's ads and stuff, and is a clean product today.

I have switched to Qihoo 360 since an year or two, and one thing I feel great about a totally freeware product like this is that, not only you get all the features for free, you don't get reminders to switch to the commercial version.

Not too sure if this is the right place to ask this question but here goes.

I recently downloaded the free version of "Malwarebytes Anti Exploit free" purely because of the good reputation of their free "Malwarebytes Anti Malware" which we are all familiar with.

This new offering, "Anti Exploit" is working as an add-on with my SRWare Iron (Chrome) and the only time I know that it's working is when I open my browser, a small window on the task bar tells me that it's operating.

Do any of you have experience with this ? .... and if so, can you tell me how it works ?

To me, it doesn't seem to be doing anything at all and I'm left wondering if it's smoke & mirrors.

Malwarebytes Anti-Exploit Free (MAEF) provides protection from exploits in the main web browsers (Chrome, Firefox, Internet Explorer, and Opera) and their add-ons and in the Java engine that is the basis for much web technology. The paid version extends this to other popular products and technologies including PDF files, media players, Microsoft office, etc.

I have been using MAEF because it provides a layer of protection that will supplement many antivirus products. The basis for much anti-virus protection is detecting known signatures whereas zero-day exploits have, by definition, no known signature so monitoring the behaviour of program code is a better way to detect new exploits that have not previously been detected.

I'm actually a low-risk Web user so I will be surprised if MAEF does detect anything. I would probably be better of using other products to harden my computer, Sandboxie and EMET are two good examples. But I am using MAEF because I wanted to see how it operates. Other products I have tried recently have been disappointing for not being unobtrusive (e.g. Kaspersky Software Updater) whereas MAEF's lack of visible effectiveness is reassuring given the excellent reputation of their other products. It also doesn't appear to use a lot of resources. Later in the year, I will probably give it a good run on my test system by comparing performance with and without MAEF running, and  going to websites with known exploits.

For those who aren't familiar with the terminology. Malwarebytes Anti-Exploit Free is designed to defeat exploits. An exploit is program code that has been written to make malicious use of design flaws and other vulnerabilities in computer systems so as to defeat your computer's security. The worst exploits are those that make use of flaws that are not known to the developer/vendor of the software. The vulnerabilities are unknown so the developer/vendor has no time to remedy the situation hence the use of the term zero-day.

Good day terrawarra :). The issues you post about, I haven't encountered on my system. I do get the popups though, and I simply close them.

Avast Free nowadays comes with several components/tools, like updater, etc, which perform extra work. I do not install any of these. I suspect that you have some or all of these installed, and the popups you mention, are occurring because these components are installed. In future, if you install Avast, deselect the unncessary (or all) components, and just select the shields that you want, and it should be fine.

Thanks Anupam,
I may try Avast again sometime in the future and give it another chance.
In the meantime, I'll give BitDefender a fair trial, assess the results and decide which one I want to go with.

We are indeed quite spoilt with so many quality freeware anti virus products out there.

Yes, there are good free antivirus nowadays. But, I guess it depends on individual taste, which antivirus you install on your system. I occasionally try different antivirus, but I keep returning back to Avast, since it is what best suits me. It is lightweight, provides good protection, and has boot time scan. All other antivirus that I tried, I had some issues with them, big or small. Avast suits me best.

With so many choices, you can always try different ones and settle on one which suits you most.

Antivirus Company Qihoo Censured for Cheating in Lab Tests

view
Best Free Antivirus Software 5 years 6 months ago George.J

Qihoo explains the misunderstandings, and requests for furthur investigation. 

http://blog.360totalsecurity.com/en/qihoo-and-testing-labs-multiple-engi...

Nothing to worry about here. Innocent until proven guilty. Interestingly it's 2 other Chinese antivirus vendors that reported the issue. We already know about the competition in China among antivirus vendors, and all this has been blown out of proportions from jealousy. Even if proven guilty, it's a minor issue because the only contradiction in the results was because their own engine was enabled and BitDefender engine enabled "by default" for the product they've given for testing. Hence calling it "manipulation of scores". Weak statement :D

Odd, the AV comp. report stated: "As part of the investigation into Qihoo 360, counter‐accusations were levelled by the company against
two fellow Chinese security firms, Baidu and Tencent.".

"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."

Default public AV engine is Qihoo's own, version submitted used BitDefender's = apples vs. oranges. In my book, that's cheating - entering a tweaked version of 'their' AV to be compared to stock versions of other AVs.

Best Free Antivirus Software 5 years 6 months ago MrBrian

There is more to this than which engines are used by default. From the report:

On requesting an explanation from Qihoo 360 for their actions, the firm confirmed that some settings
had been adjusted for testing, including enabling detection of types of files such as keygens and cracked
software, and directing cloud lookups to servers located closer to the test labs. After several requests for
specific information on the use of third‐party engines, it was eventually confirmed that the engine
configuration submitted for testing differed from that available by default to users.

I hope AV Comparatives check only for those keygens and cracks that are malicious - as in having a unwanted effect on the OS and user software/connections - many keygens/cracks are actually clean.

Best Free Antivirus Software 5 years 6 months ago George.J
More info at their FB page. 
Qihoo: " many popular software add-ons in China that are flagged as malware by the AV-C definition are in fact performing proper functions and not malicious ... (they) are flagged as malware by the AV-C definition ... To satisfy the security needs of both the domestic market and the need for foreign lab testing, all Chinese security product vendors make modifications to standard domestic versions for foreign lab testing to showcase the effectiveness of the basic protection capabilities of these products"
My thoughts about this: If AV-C even all considers keygens and cracked softwares as malicious, and Qihoo tweaked the settings for the lab results to find them as malicious, I'm personally offended by the first statement. Many of these cracked softwares aren't infact malicious. They are just pieces of reverse engineered code to revoke the licensing of the softwares. We're talking about ethics here, but definitely not malware. On many torrent sites popular uploaders specifically state the fact that if you certainly like a product, you should go and buy the product and the ones that they have uploaded are basically for testing the software for longer periods of time.
 
In my own testing Qihoo's own engine is extremely good if you are connected to the internet. When BitDefender's engine built into Qihoo is enabled, I've found that it detects patches, keygens as malicious among the one's which actually aren't malicious. However when disabled, the same isn't the case. This means that although these files can be considered safe in an average amount of cases, doing so would cost them a place at these lab results. This leads to more false-positives when BitDefender's engine is enabled, hence the reason why Qihoo hasn't turned on these engines by default during installation. They have no choice but to enable them for the lab results.

I too can understand why this was done by Qihoo although many will still make an argument for it being wrong. There is also a danger that this sort of issue diverts users from the real reasons why they get infected and towards complicit reliance on test results.

When I first began servicing live customers, the folks that could afford to pay for these services were at least 75% installed with the “leading” :D commercial antivirus products, so why were they infected? The reasons of course were as diverse then as they are now but the bottom line is folks still think they can install security software and then surf the internet with impunity. Naturally they seek guidance about these products and use test results as a basis for choice. It's a pity therefore that next to no effort is made to research the methodology of individual tests to see how these might apply to their own usage habits. Take the following for instance which is an extract from one of the much lauded PC Mag tests.

“FortiClient is only the sixth product I've put through this particular test, so I can't say precisely what its score means. Still, having another product block nearly twice as many suggests that 40 percent isn't great. Do note that of necessity the products aren't tested using precisely the same samples. Rather they're all tested with samples detected no more than a day earlier—the newest samples I can get”.

Really? So car “A” fails the crash test but the wall it was driven in to was different to that used for cars “B” and “C”.

At the extreme end of this mess are the YouTube garbage in, garbage out tests where amateurs chuck a handful of URL's at something and then rate it based on the results. YouTube is entertainment folks, not a consumer testing authority.

If people believe Qihoo's actions were a deliberate attempt to deceive, they are free to use another product. I have Panda on both of my dual booted desktops and nothing nasty has bothered me yet. MC - Site Manager.

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.

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.
