I am using Bitdefender, due to all the excellent reviews of their product. I did have a problem with Ccleaner locking up my system whenever I did a scan.
According to the forums on Bitdefender, to avoid this problem, all you have to do is turn off the virus shield on Bitdefender, whenever you run a scan with Ccleaner. Since I started turning off the virus shield, to run Ccleaner, I have not had any problems. Just make sure you turn it back on when you finish cleaning with Ccleaner. I love this anti virus, and I do not mind a little extra work, to keep it on my computer. I wrote this as a help to those that maybe having the same conflict with Ccleaner. I hope I was of some help with this issue.

view
Best Free Antivirus Software 2 years 7 months ago Chiron That's a very strange issue. I hope it's already been reported as a bug on Bitdefender's forum and will be fixed in subsequent updates. That said, I'm glad to hear of the workaround, and will let others know if I hear of anyone running into the same problem. Thanks. view

Chiron,

The conflict between Bitdefender Free Edition and Ccleaner, has not been fixed. I am still having the problem. From what I understand, Bitdefender has no plans to resolve the issue.They say that it would put the computers that their product is protecting at risk, to resolve the problem. I was told by Bitdefender to do the work around, of turning off the Virus Shield, when cleaning with Ccleaner, or to delete one or the other. Bitdefender is a little arrogant, when it comes to their product. I don't blame them for that. I think they have a very strong product. So if they think that resolving the problem would put my computer at risk, then I have to agree with them to not resolve the issue. Both Bitdefender and Ccleaner are great products to have on your computer. So I have chosen to do the work around.

view
Best Free Antivirus Software 2 years 7 months ago Chiron Thank you for updating us about this. I'm really not an expert in how products are coded and thus will not argue with them about this. However, it does seem strange that other products do not have the same issues. Either way, I suppose it's a relatively minor issue for a good free AV. Also, for anyone else reading this, if the issue is bothering you too much you can also switch to one of the other great AV's in this article. Thanks again. view

Hi!

I should say online activation is "optional".

Have been testing AVG, Avast! & Avira. So my 2 cents, for what its worth:

1. Whilst AVG certainly is very capable and suitable for the vast majority of users, it does tend to be a bit "heavy" and slow, but all round a solid product.

2. Avast! may well be rated highly, BUT be warned.... its a bandwidth hog, doing all sorts of strange things in the background. At first I thought it was a bug or something weird going on... but a quick search on Google shows that this is well known. If you are using 3G or any form of controlled bandwidth, suggest you leave Avast! well alone! Setting to a minimum file only protection did not seem to help the situation either.

3. Avira.... have since 2013 removed their intrusive ads (This needs to be updated in the above summary). I currently use this Anti-Virus, and have no issues so far!

view
Best Free Antivirus Software 2 years 6 months ago Chiron Thanks for letting me know about this. I have now updated the information in the article. view
Best Free Antivirus Software 2 years 6 months ago Chiron I agree with George.J. Although it will run fine for 30 days without registration, it will stop running after that time runs out. Therefore, that is why I say that it requires registration. If you have any questions about that please feel free to ask. Thanks. view

In hopes of hardening my older XP Pro lap top before the SHTF event in April, I loaded up Avast and was initially satisfied with how it did it's job. Then I reached a 30 day anniversary and the constant nags started. Now I have no working anti-virus and I am also unable to remove Avast or disable it's constant nag pop ups. As of this date I would rather be scalded than pay the Avast pirates a penny for their miserable product.
Anyone looking for free anti-virus I would advise stay well clear of this nasty, intrusive, offering.

The free version of Avast requires that you register with them to use it for more than 30 days.

I'm guessing that you didn't do that?

view
Best Free Antivirus Software 2 years 6 months ago Chiron As sicknero mentioned, did you register the product? Regardless, it should still be able to be removed (and if it can't this sounds like a bug), but the reason it's nagging could very well be because of the required registration. Thanks. view
Best Free Antivirus Software 2 years 6 months ago Chiron Thanks. I've now added that it also includes the cloud. However, I did not see any indication that the new browser safety addition is yet included. It seems to be in Beta. Thus, I did not add that to the article yet. As for updating this article to better compare the products, I am still trying to find the time to do that. I have been very busy lately, but do still plan to update this article such that it will better differentiate between the real-world protection offered by these various products. At that time I'll be using the results from multiple testing agencies. Thank you. view
Best Free Antivirus Software 2 years 6 months ago Chiron I have removed the warning about Avira from the article. Apparently they now provide free users access to their cloud as well. I have updated the article to mention this as well. As for the other products, I will be updating this article (once I have more time) to better differentiate between the real-world protection offered by the various products. To do this I will draw on the results from several testing agencies. However, I am very busy right now and not sure when I'll find enough time for a drastic rewrite and research which this necessitates. That said, it will happen eventually. I was not aware of the issues which Avast causes on systems with slow internet. I assume that is likely caused by cloud-based activities. Has anyone else run into a lot of problems with Avast hogging the band-width? If so I'll update the article to warn about that. Thank you. view

Your feedback is much appreciated, and will be very helpful. Thank you. view
Best Free Antivirus Software 2 years 6 months ago bernardz Although it is not as good an antivirus system as these above, MSE does have the advantage that it can run on slow machines without draining the power too much. It also has no legal issues about commercial or non commercial use. For these reasons for many people, it is actually a better solution. view
Best Free Antivirus Software 2 years 6 months ago Chiron If you check the results for MSE, you will find that it consistently scores near the bottom. Thus, it does not offer sufficient protection for me to recommend it in this review. For users who find the other antivirus products in this review too resource intensive, I would recommend that they try Panda Free. It should be quite fast, even on slow machines. As per legal issues, Comodo Antivirus is free for commercial use, although if the company has many computers they may wish to consider Comodo Endpoint Security, which is paid. That said, there is still a free product recommended in this review which also works for commercial environments. Everything taken into account, I do not think that it is a good idea to recommend MSE. It just doesn't provide the level of protection which people deserve. Thanks. view

Isn't v7 in beta still?

view
Best Free Antivirus Software 2 years 6 months ago Chiron No it is not. The final version has been released to the forum, although those running V6 will not yet receive an automatic update. Also, I'm not sure whether the main download page directs users to V7 or V6. Regardless, the release topic on the Comodo forums will allow users to download V7 final. Thanks. view
Best Free Antivirus Software 2 years 6 months ago sicknero

Thanks Chiron, I'm running v6 CIS and as you say it isn't reporting any available updates.

I had a look around Comodo and FileHippo etc (the screenshots on FileHippo look like v5?) and the Comodo download appears to be v6 still, so I thought I'd ask here.

Cheers.

view
Best Free Antivirus Software 2 years 6 months ago Chiron I thought about this some more, and what I have ended up doing is I edited the information so it now reads V6.x. This way there will be no confusion. Once V7 is made available through the auto-updater I will update this to refer to V7.x. Thanks for pointing this out.

Not directed at Chiron specifically but is a direct link to the v7 download or topic to much to ask for? Normal download process gives me V6 and I'd like to avoid having to hunt through their forum for it.

Best Free Antivirus Software 2 years 6 months ago Chiron From my experience you won't get too many popups at all, even initially.

Best Free Antivirus Software 2 years 6 months ago Chiron Thanks for pointing this out. I would advise that users download and install V7 rather than V6. It is the newer version, and appears just as stable. However, until the main Comodo Antivirus page updates such that it is V7 which is downloaded, I will keep the version listed as V6.x. This way it will not confuse users who are already running it, and try to see if there are any updates. Thanks. view
Best Free Antivirus Software 2 years 6 months ago Chiron Unless I'm mistaken, the main installer contains the files for both the x86 and the x64 versions. During installation it will automatically install the correct files. It also contains the additional software, which I warn about in my review. I believe some 3rd party sources may remove those extra software. I hope this is helpful. Thanks. view

From the BD Free Manual:

What is Bitdefender Antivirus Free Edition?
Bitdefender Antivirus Free Edition is an antivirus program designed to be fast and
to minimize user interaction, while sacrificing nothing of the malware detection and
removal capabilities that Bitdefender products are generally known for.

Also a BD staff confirmed in Wilders forum. His name is Iulika0069.
http://www.wilderssecurity.com/showthread.php?t=338408
He confirmed BD free provides same protection as paid. The thread is huge, its hard to find the post. There are many post by him & you will get all the info about BD free.

view
Best Free Antivirus Software 2 years 6 months ago Chiron I'll try to search through that later. It really is a huge thread. However, here is an excertp from the main Bitdefender Antivirus Free Edition page here: They say that "Bitdefender Antivirus Free Edition shares some of the revolutionary technologies that allowed our main product line to outpass major competitors such as AVG, Avast or Avira." http://www.bitdefender.com/solutions/free.html I'm not sure exactly which technologies the Free version does not have, but seeing as they specifically state that technologies have been removed from the Free version, I assume that the Free version also would not protect the system quite as well as the paid version. However, when I have the time I will look through that thread and try to see if perhaps I am wrong. If you run across a relevant post before I do please direct me to it. Thanks. view

The link you gave mentions all the features BD free has.
Realtime
Active Virus Control
Intrusion Detection System
B-Have
HTTP Scanning
Anti-Rootkit
Early Boot Scanning
Autoscan

The Wilders thread I mentioned, if you go through the thread, you will see BD staff confirmed on the above features too.

I think the missing stuffs in BD free compare to paid are the additional stuffs like, safepay, wallet, rescue disc, parental control, etc...

I will try to find few important info posted by BD staff on the wilders thread & let you know.

Best Free Antivirus Software 2 years 6 months ago Chiron I did notice that. What I'm not sure about are the further details.

If you are not sure of the details then I think you shouldn't mention "protection level is not identical with paid".

view
Best Free Antivirus Software 2 years 6 months ago Chiron Thanks for pointing out the confusing wording. I have now updated it to read that "the level of protection provided has not been shown identical with the paid version, which is why I did not use the results for the paid version in my analysis". If anyone can show that the level of protection is absolutely identical then I can use the results for the paid version. This can be done for Comodo Antivirus. However, until someone can show me that the free version of Bitdefender offers exactly the same level of protection, not just the same components, I cannot use those results. I hope that makes sense.

A few months ago I tried Comodo on my XP machine, and found I had to turn off the internet connection before I could boot it. Otherwise Comodo took over the machine, and just sat there doing who knows what (my guess: a download of the whole malware signature database, followed by a full-scale scan) that monopolized my computer and did not respond to any interrupts for hours on end. Fortunately that computer has a mechanical wireless on/off switch on the front so I was able to break in and try and tweak the thing into proper behaviour, but the mitigation was slight; I eventually wiped it in disgust. My experience with avast was nearly equally bad, just enough less offensive that, faut de mieux, I elected to tolerate it for now given the oncoming demise of MSE for XP.

Obviously, I need the best fortifications available constructed around my XP facilities. Equally obviously in the past few months there have been major changes in all the anti-virus offerings and how they work. Maybe things have improved.

Clarification is needed, too. I got an "update" notification from Comodo offering added features. But a close reading suggested (the weasel=wording and misdirection is shameful) that they were trying to sell me an upgrade, likely at exorbitant subscription expense. I could be wrong - but why are they playing this game in the first place?

I just want an antivirus that works, and don't mind running a selection of separate anti-malware programs should these be necessary. I know the internet is a dangerous place and will defend as best I can. But programs that take over and run away with my computer, or try con games with me, are not things I'm eager to take on - even with your recommendation.

view
Best Free Antivirus Software 2 years 6 months ago George.J Protection level is not just about the percentage of samples that an antivirus can identify, other features are added to a paid antivirus solution to keep you safer.

Best Free Antivirus Software 2 years 6 months ago Chiron Now that you mention it, that is a strange place. However, now that you found it is everything up and running correctly? view
Best Free Antivirus Software 2 years 6 months ago naren

What I am trying to say is........

For example - AVG free autoupdate is not often like paid. This too can affect the protection. No Webshield/Online shield in free like paid.

For example - VB RAP test - You can see there is difference in protection by Avira free & paid. Avira free doesn't provide Webshield like paid. Avira Browser Security in free is not like Webshield in paid, there is no HTTP scanning in free like paid. Avira too doesn't autoupdate often like paid.

I know there are tests available for these AVs & that can be put in the review. But the same thing can be said about these free AVs i.e protection not identical with paid. You didn't mention this for these AVs but you mention this for BD free, that kind of looks unfair to BD free.

About BD free - I am little busy, when I will be little free, I will try to scan Wilders links & provide you the facts/confirmation about BD features/protection by BD staff. If you have time, you too try to do so.

I have tested & compared BD free with paid & other free AVs too & I find it an excellent free AV especially for average users. I find it better than all the free AVs mentioned here in terms of protection & everything for average users, not including CIS as CIS is way better than all the AVs mentioned here & recommended for advanced-intermediate users. I know my tests doesn't count, just sharing my test experience.

After trying comodo antivirus for only two days, i had no choice to uninstall it before my PC had had a heart attack. While running a full scan Comodo Antivirus brought my machine to a halt, the Quad core CPU was 100% most of the time. There is no doubt the spec of the software is pretty impressive for a free product, but be aware it may take over your machine while it takes an eternity to scan your drives . I have reinstalled AVAST which i have been using for years combined with comodo firewall. The CPU hardly moves during a FULL Scan allowing you to go about your business.

I run Comodo CIS on two fairly low-end machines (single-core 2 and 2.3 CPUs) and I've not found this problem myself for several versions now. Running a scan typically fluctuates between 10 and 40% rising sometimes to about 90. Later versions have the option to run scans as a background task as well. I've not found it to be noticeably slow compared to other scanners.

view
Best Free Antivirus Software 2 years 6 months ago Chiron From my experience this is likely due to some sort of interference, or a problem which somehow occurred during installation. Please try reinstalling it by following the advice I give in this post: http://forums.comodo.com/install-setup-configuration-help-cis/most-effec... and let me know if that solves this problem. If it doesn't let me know. Thank you. view
Best Free Antivirus Software 2 years 6 months ago Chiron The reason I did not mention that the protection offered was not the same for many of the other Free AV's is because the Free versions were tested by the testing organizations I used for this analysis. Thus, there was no need to compare the Free to the paid versions. I could just look at how the free versions compared. However, I cannot do this for BitDefender because the Free version has not been tested by those tests. The only reason I mentioned it is because if I didn't many users may mistakenly think I could use the results for the Paid version. Thus, this is just an explanation to prevent confusion about why this particular methodology was chosen. Also, I have no problems with Bitdefender Free. It does seem like a very good product. If I didn't think it was I would have removed it from the review altogether. It's just that I'm trying to keep this review more factual. Thus, as I have no definitive data on how it compares to the others (using the real-world tests I referenced) I cannot recommend it over them. I'm sorry if my wording suggested otherwise. Thank you. view
Best Free Antivirus Software 2 years 6 months ago Chiron Which version was this? I know that for V6 and V7 it only requires an initial update and then a quick scan. V5 used to require a full scan.

You have mentioned in the review that it is not tested yet by any testing organization so you cannot recommend it above others. I totally agree here.

But I do think "protection level has not been shown identical with paid" is not required.

Collect facts/info about BD free & put it in the review would be better.

I am defending BD free coz..........
Before using it, I read all the posts i.e above 100 pages in the Wilders links that I have mentioned in one of my previous post so I know the facts/info about BD free. I can mention here but that would not be enough so I asked you to go through the Wilders thread & get all the facts/info.

Just my 2p-worth of experience with Bitdefender Free AV. After I installed it I could no longer print to my networked printer. The documents just sat in the queue and never printed. Uninstalled BD and all was well. I even tried reinstalling the printer after BD, but it still didn't work.
Decided to put Avira on instead and have had no problems.
I did a quick web search for problems, which only threw up issues with the full Internet Security Suite and its Firewall - which, of course, isn't part of the free AV prog. I guess I could have dug around some more, but life's too short.

view
Best Free Antivirus Software 2 years 6 months ago Chiron That is a strange issue. I suppose the best approach, assuming you would like to try Bitdefender again, would be to ask that question in their forums. However, if you're happy with Avira then I suppose there is likely no need. If you have any questions about any of the other AV's listed in this review let me know. Thanks. view
Best Free Antivirus Software 2 years 6 months ago Chiron In the review I mention that the only reason I even bothered to say that the protection level has not been shown to be identical with the paid is that I cannot use the results for the paid in my analysis. I think that makes sense to put that there. Without it many users would accidentally compare it with the results for the paid version. As mentioned previously, I do believe that Bitdefender Free is a very good product. If I did not believe that I would have removed it from this review. I did that with MSE, which was previously recommended. As for putting in additional information about Bitdefender Free, please provide me with your recommendations about the type of information which could be added. This sort of information will likely be very helpful for my next re-write. I did assume that you were the same naren from the Comodo forums, although I was not certain until you just confirmed it. I do appreciate your comments, and I also hope you are beginning to better understand my position. Comparing AV products is a very difficult task, and there is no one perfect approach. Thank you. view

I have been testing a few antivirus above and having a slow laptop (C2D 2.0ghz, 4gb RAM), I really care about the performance. And here is my take on each antivirus.

Since Avira implemented the cloud service, I have noticed some slowness (boot time and overall response time) compared to previous experience. Uninstall, and reinstall with cloud service ticked off seems to make it more responsive however it is not as fast as before.

For Avast, there is not much performance degradation on the new program update, everything seems working fine.

For BitDefender, it is very slow, and I still wonder why would people rate the performance as "high". My boot time increase for about 20 seconds compared to no antivirus installed after switching to Bitdefender. Try to give it a whirl, but the responsiveness is worse than Avira (high i/o activity).

AVG as usual, still slow however the recent version seems quite improve than before. Much better than Bitdefender but slower compared to Avira.

Machine with Panda Cloud seems to have the fastest overall response, with boot time only increase for about 3 seconds compared to no antivirus installed. However, my laptop is not 24/7 connected to internet, thus I have trust issues during offline operation.

Currently, in terms of overall performance and boot time impact would be:
Panda > Avast > Avira > AVG > Bitdefender

I have not tested latest COMODO due to time restriction (the last time I evaluate COMODO antivirus is in 2012), can somebody shed some light?

How much is the RAM usage and the boot time increment compared to other AV listed above?

well the avast 2014 is not that powerful in my experienced than the avast 2013 in terms of detection rates specially on worms! i have recently installed newly and updated version of avast 2014 on 3 different pc's however, the 2014 edition does not detect worms and their behavior on the computer. So why would I trust this antivirus program? worms are sometimes a kind of destruction to your files specially in flash-drives for it has a auto delete and auto hide components. fortunately I have been using Microsoft Security essentials for detecting almost all kinds of worms.

view
Best Free Antivirus Software 2 years 6 months ago Chiron Each AV will run somewhat different on different computers. Thus, I would advise checking Comodo Antivirus yourself and seeing how it fares. However, in general, I was planning on trying to locate somewhat reliable performance statistics for the AV software listed in this review for one of the upcoming updates. Once I have done that I will be able to supply more detailed information. Thanks. view
Best Free Antivirus Software 2 years 6 months ago Chiron Every AV will have good days and bad days in terms of detection. However, I can tell you that nearly every test will put Avast far above MSE in terms of both detection and protection. That said, it is possible that Avast's detection of certain types of malware is not as good as that for others. Please let me know how you tested it against worms. How many samples did you use, and what was your methodology? Thanks. view
Best Free Antivirus Software 2 years 6 months ago Chiron Thank you. I will update the Bitdefender information during my next rewrite. view
Best Free Antivirus Software 2 years 5 months ago George.J Why does PrivDog extension get installed, even when I've deselected it from installation options of Comodo IS? Is this normal or a bug? view

Chiron,

I have looked through you sources as follows :

AV-Test

AV-Comparatives

Dennis Technology Labs

What I found was, is that Comodo Antivirus was not presented as a stand alone product, but as a suite. I only found three from your list of antiviruses, that presented their antivirus as a stand alone product. As per this link :

http://www.av-test.org/en/tests/home-user/windows-7/janfeb-2014/

I have seen testing of antivirus programs, that tested much better within a suite, than as a stand alone product. Do you have any test results of Comodo Antivirus as a stand alone product?

Otherwise I will have to go with one of the other three that were tested as a stand alone product. At this point, I do not see how Comodo Antivirus stands as the best, when I can not find their Antivirus, tested as a stand alone product.

view
Best Free Antivirus Software 2 years 5 months ago Chiron I should clarify this in the article as well, and I will during my next rewrite. I can use the results for CIS because the core protection, at least against any malware which makes its way onto the system, is identical between the two products. If there does become a difference then I will no longer consider the results for CIS to be comparable to Comodo Antivirus. I hope that makes sense. If you have any questions, or do not agree that the protection against malware on the system should be considered identical, please feel free to ask. Thanks. view

Hi,

So far i used and recommends/install Comodo Internet Security to my neighborhood. Though comodo antivirus never had a chance to be in any top 10 best antivirus reviews in my experience my system is stable so far and can be commercially used that does not required activation. My downside is i never used my pc like i dont care..?! Like i dont go to any site that has bad ratings on it or i feel that a site is a bad site or a link is a bad link - I dont download and open any file which is unknown to me. Bad thing is that few people does that. It was confirmed to me when i recommends it to a company and they installed it to hundreds of computers - they say most of their users dont really care what they click because they know someone will fix it.

I wanted to tried avast and bitdefender but it does required registration and activation - and it is a bad thing for offline users. They should remove registration and activation. And should be a standard for any free software.

Best Free Antivirus Software 2 years 5 months ago Chiron Thank you for your feedback. My problem with most of the antivirus reviews is that they tend to put most of the emphasis, in one way or another, on detection of threats. However, I am of the opinion that for a user in the real world what really matters is whether the computer was protected from infection or not, regardless of how it was protected. As for Avast and Bitdefender, I do understand what you mean about activation. However, hopefully there is a way you can connect your computer to the internet for the small time required for activation. Still, I agree it would be best if they could keep track of users in some other, less intrusive, manner. Let me know if you have any other questions. Thank you. view

Chiron,

It has come to my attention that AVG will not detect any part of Opencandy as malicious. AVG and Opencandy now have a deal that AVG not detect opencandy as malicious. That offends me !! If that is truly the case, then AVG does not deserve to be on your list !! For this reason, I personally will never put AVG on my computer ever again !!

view
Best Free Antivirus Software 2 years 4 months ago MidnightCowboy None of us here, and I guess most outside, do not like OpenCandy or how it operates, but it is not malicious as indicated in our information page about it here. http://www.techsupportalert.com/content/controversial-advertising-progra... We also need to remember that unless as individuals we never search for deals and have completely opted out of the consumer society we helped to create, then we are all responsible for OpenCandy's existence. The bottom line though is there are plenty of OpenCandy free alternatives for most software categories, and the offers it generates are easily avoidable if care is taken during the install process.

Midnightcowboy,

I agree with everything you said 99% !! But what I have a problem with is that an antivirus program creator can be paid not to detect one thing or the other. That is a big problem !!
As far as Opencandy not being malicious, that is a matter of what your definition of what malicious is. My definition of malicious defines Opencandy as malicious. But that is not an arguable point. Just a matter of opinion. I think you could put a disclaimer with AVG that it does not detect Opencandy. Thank you for your response!! You will hear no more from me on this matter !!

Best Free Antivirus Software 2 years 4 months ago MidnightCowboy Please provide links to substantiate your claims about AVG being paid not to detect OpenCandy otherwise you risk the inevitable conclusion that your posts are just trolling. MC - Site Manager. view

Midnightcowboy,

I have no link to give you. I read it in a Magazine, and I do not remember off the top of my head what the name of that magazine was. It is not my intention to be trolling, Please feel free to delete my comments. If I find that magazine in the future, then I will be back to give you that info. Have a GREAT DAY sir !!

Not many AV scanners do detect OC inside installers.

For instance the FreeFileSync installer, which runs the Open Candy exec OCSetupHlp.dll, is passed by most of the major AV providers. Malwarebytes flags it as a PUP.

Best Free Antivirus Software 2 years 4 months ago Chiron If you, or anyone else, can provide a link which shows this I will look into it. However, the most I would do is put a disclaimer as the program would still be effective at protecting users from truly dangerous malware. That said, I will need to see a link before any action can be taken. Thank you for bringing this to my attention. view
