Antivirus software provides an essential layer of protection from viruses, trojans, worms, spyware, adware, dialers, keyloggers, and rootkits. However, don't let the name antivirus confuse you. These days every good antivirus has good detection rates for all forms of malware, not just viruses. The term malware includes viruses, trojans, worms, spyware, adware, dialers, keyloggers, rootkits, and any other software which performs malicious activities on a computer.


Sadly, the amount of malware currently in circulation is so large that no antivirus could possibly detect all of it. Despite vendor's claims, no single antivirus solution can detect nearly all new malware. There are some products out there, including some in this review, which include technologies which are able to adequately protect a computer, but any product which relies mainly on detection is statistically doomed to fail eventually. Also, using more than one real-time antivirus at the same time uses much more system resources, can cause system errors, and can even reduce protection due to unintended conflicts. For my advice on how to compensate for these weakness of antivirus products please see my other article about How to Stay Safe While Online. Having a good antivirus product does go a large way towards adequately protecting your computer, but in this day I would highly recommend that you add additional layers to your security arsenal.


Below I have reviewed some of the most effective Free Antivirus products currently on the market. In order to make this review more unbiased, although I do of course admit that my own intuition and experience does affect my judgment as well, I came up with a particular methodology for comparing these products. This methodology is described in the following section.

Recent Changelog:

10/7/2014-Re-inserted explicit statement mentioning that I am a volunteer moderator (not employee) on the Comodo forums.

10/9/2014-Linked to instructions on how to make sure Bitdefender Free can be installed in English, and added MSE to list of unsuitable AV's.

11/14/2014-Added additional information about Bitdefender Free.

Methodology For Comparing Products

The main motivation behind why I came up with this particular methodology for this review is that I value system protection against real world threats above all other categories by which an antivirus is commonly judged. It does not matter to me whether an antivirus protects the user by detecting malware, blocking dangerous sites, behavioral analysis, sandboxing, or any other approach. The most important thing is that at the end of the day your system is safe from infection. Thus, that is the attitude I have taken towards reviewing these products. My criteria is entirely based on protection, not cleaning. Therefore, if you believe your computer may be infected please first see my article on How to Know If Your Computer Is Infected before continuing to read the rest of this article.


I have located reputable Antivirus testing organizations which claim to test products against situations which resemble real-world situations. I narrowed these down by further requiring that the organizations have a relatively long record of producing good, seemingly unbiased, results. The organizations I ended up with, and therefore used for this review, are:



Dennis Technology Labs

From here I looked at all tests spanning back over the last two years. However, if there were more than three tests within that range I used only the most recent three. Also, if given the choice between results from different operating systems, I chose that for the most popular operating system. At the moment Windows 7 is the most popular operating system.

Also, I only considered results if it was specifically the Free Version which was tested. This is because the results for the Paid Version of the products in this review, with the exception of Comodo Antivirus (which has the exact same protection for its Free and Paid versions), are often quite different from those for the Free versions. Many marketing teams try to cloud this difference, but for the purposes of getting the most reliable information I am strict about this. Unless it can be explicitly proven that every protection mechanism is exactly identical to the free version the results for paid products are not considered in this analysis.

In addition, I did not count it against any of the products if they were not tested by multiple organizations. As long as they were tested by at least one, within the above-mentioned period, they were considered. This criteria was chosen because there are many reasons to choose not to participate in a test. Thus, it should not be held against the product if they were not tested by multiple agencies. However, if they were not tested by any, this makes it impossible to compare them in an unbiased fashion.


Once this data was collected, I then looked at the overall results for the Free Antivirus products discussed in this review, and ordered them mainly according to the quantitative results. However, my own knowledge of the products, and the reviews and experiences of others, were also considered. The results are presented and discussed below.

Discussion And Comparison

Comodo Antivirus is my top pick for advanced users, or for Intermediate users who are okay with an antivirus software which will occasionally ask them for input. However, if you do not fall into those categories, or for any other reason find it to not be a good fit for you, then you will likely find my next pick suitable. Also, for those who prefer a complete solution, there is always Comodo Internet Security (CIS), which is also free and includes a firewall in addition to all other components which already come with Comodo Antivirus.

Firstly, I will note that I am a volunteer moderator (not employee) on the Comodo forums. However, this is certainly not the reason I chose this for the number one position. The reason I made this my top pick for advanced users or users who are okay with a somewhat talkative antivirus software, is because it is the only product which I feel confident saying that it will protect you against nearly 100% of real-world threats. This is because it maintains a white-list of known safe applications. Then, all unknown applications, which include all unrecognized malware, will be sandboxed and isolated from the rest of the system. Thus, this product provides very strong protection against even zero-day malware.

Comodo Antivirus also uses the cloud to facilitate the detection of the most recent malware, as do many other Free Antiviruses reviewed in this article. It will also analyze unknown applications for suspicious behavior, and alert the user accordingly. However, as mentioned previously, users who do not want a somewhat talkative antivirus should continue to my next pick. Also, by default Comodo Antivirus has small advertisements (which can be disabled as shown here). Also, please see my notes in the Quick Selection guide for advice on how to avoid unwanted software during installation.


Panda Cloud AntivirusPanda Cloud Antivirus is an excellent choice for average users, who may find Comodo Antivirus too confusing. It has a simple interface, completely automated features, access to cloud-based protection, and has been shown to be very good at protecting a computer. Panda Cloud Antivirus has a behavioral blocker, web protection, and access to cloud-based protection, all of which will help increase your security. The protection offered by this product is very strong. However, do note that it will auto-quarantine files which it believes to be dangerous.




Avast! Free AntivirusAvast! Free Antivirus has very good protection rates. Avast has many different protection shields, boot-time scanning, a behavioral blocker, an internet site ratings plugin, script malware protection, and access to cloud-based protection. It's arguable whether their ratings plugin offers comparable levels to Web of Trust, but the script malware protection can prevent certain browser exploits, a feature not available in any of the other free AV's reviewed.

However, do note that Avast requires a free registration to function after 30 days, and the default installation installs the Chrome browser unless you uncheck it. Also, note that the OpenCandy advertising component is integrated into the Software Updater tool in Avast. More information about OpenCandy can be read here. Thus, if a user selects this option during the install they will end up with OpenCandy on their computer. My advice would be that if you want to install Avast you should not use the Software Updater tool.


AVG Anti-Virus Free EditionAVG Anti-Virus Free Edition is also a good choice for average users. My analysis of the results, as discussed in the methodology section, does show that it does a decent job of protecting your computer. However, it appears that the above Antivirus products tend to do better. Also, it comes with advertisements (but they can be disabled).





360 Total Security is also a good choice for average users. Although it has gotten some very stellar reviews, the results I found from looking at the results from the testing agencies referenced earlier in this article show that the protection it provides is roughly the same as AVG, but certainly not as effective as Comodo, Panda, or Avast. This product uses multiple antivirus engines to detect malware. It has cloud protection, and also uses the Avira and BitDefender engines, although these are not enabled by default. For more information about this antivirus, see the separate article on this page.

Avira AntiVir Personal EditionAvira AntiVir Personal Edition is another product which has a very good reputation. However, the free version was not tested by any of the three testing organizations I referenced in my methodology. Therefore, I cannot currently recommend it above any of the previously mentioned products.

However, other comparative tests do show that it has very high detection rates for malware. Also, many users have used it and found that it is very effective. Also, Avira provides access to cloud-based protection. AntiVir is certainly a good choice for a free antivirus, but due to the lack of real-world testing, at this time I cannot recommend it above the other products in this review. Hopefully in the future they will have the free version tested by these organizations as well.



Bitdefender Antivirus Free Edition

Bitdefender Antivirus Free Edition is another free antivirus product which has a very good reputation. However, the free version was not tested by any of the three testing organizations I referenced in my methodology. Therefore, I cannot recommend it above any of the previously mentioned products.

The engine for this product appears to be very similar the commercial product, although there are some tweaks. However, the level of protection provided has not been shown conclusively to be identical with the paid version, which is why I did not use the results for the paid version in my analysis. Bitdefender Free has both local and cloud-based definitions. Thus, users always have access to the most up-to-date definitions. It also has an effective heuristics engine, and uses a component called the Active Virus Control to monitor applications in real-time for suspicious behaviors. In addition it also has a webshield, which seems quite effective at protecting users from both malware infested and phishing sites.

The user interface for this product is very minimalist. Thus, it may be attractive for novice users, although more advanced users may be frustrated at the lack of customization. However, it has no offline installer, and it also requires registration to continue using it past 30 days. Bitdefender Antivirus Free Edition is a good choice for a free antivirus, but due to the lack of real-world testing, at this time I cannot recommend it above the other products in this review. Hopefully in the future they will have the free version tested by these organizations as well. Also, note that if you are having trouble getting Bitdefender Antivirus Free Edition to install in English please follow the steps in this post.


Please help us by rating this review

End-Note: Please note that I also looked into Forticlient , Kingsoft, and Microsoft Security Essentials. However, I found that the protection offered by these products is subpar. Thus, if you are considering using Forticlient or Kingsoft I would strongly recommend that you instead consider another of the products reviewed in this article.

Quick Selection Guide

Comodo Antivirus
Gizmo's Freeware award as the best product in its class!

Runs as a stand-alone program on a user's computer
This has full real-time protection capability, including real-time antivirus, behavioral blocking features, cloud-based protection, and an automatic sandboxing function which protects users from nearly all malware.
The automatic sandboxing function, although not very intrusive, may be too talkative for some users. Also, by default non-intrusive advertising is enabled (although it can easily be turned off). Also, Comodo Secure DNS, which is offered with Comodo Antivirus during installation, tends to have many false positives. Thus, I would suggest that you untick the option to Enable Comodo Secure DNS during installation.
Version 6.x
32 and 64 bit versions available
Unrestricted freeware
There is no portable version of this product available.
Windows XP, Windows Vista, Windows 7, Windows 8.x

Take care to avoid the installation of unwanted software during installation. To do this use the customized installer button, which is on the lower left-corner of the screen during installation. Additional software, including a browser, an ad-blocking addon, and an option paid service which would allow Comodo technicians to help you with computer problems, are all included by default.
Also, I would suggest that you untick the option to Enable Comodo Secure DNS during installation. It tends to falsely block many safe pages.
Also, note that although the download page linked to above does not list Windows XP as being supported, Windows XP x32 is fully supported, although Windows XP x64 has significant limitations.

Panda Cloud Antivirus
Combines a web service with a stand-alone program
High detection rate of malware, web protection, some behavioural blocker features
Detection rates of real-world malware is slightly lower
Version 2.x
32 and 64 bit versions available
Free for private use only
There is no portable version of this product available.
Windows XP, Windows Vista, Windows 7, Windows 8.x
Avast! Free Antivirus
Runs as a stand-alone program on a user's computer
This has full real-time capabilities, behavioral blocking features, script malware protection, and a low rate of false positives.
Default settings require certain user interaction. It is bundled with Chrome browser by default, and if not carefully avoided during installation the user may accidentally install OpenCandy (see discussion for clarification).
Version 9.x
32 bit but 64 bit compatible
Feature limited freeware
There is no portable version of this product available.
Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8.x, Mac OS

Take care to avoid the default inclusion of the Chrome browser and OpenCandy during the install process by using the custom install option. The attempt to install these will also be repeated at the program update if the automatic option is chosen.

Thank you for pointing this out to me. I have now added a warning to the article.

by BroKen on 24. August 2014 - 10:42  (118177)

Your warning: "Take care to avoid the default inclusion of the Chrome browser and OpenCandy during the install process by using the custom install option" (accessed 2014-08-24). That has been bothering me. :)

It would be very unusual to be given the option to reject OpenCandy. What you can reject are the downloads suggested by OpenCandy, but those come only AFTER OpenCandy itself has been installed, assigned you a permanent identifier, snooped through your stuff, phoned home info about your computer, your software, your geolocation, etc. It then selects downloads based on that info and on its previous interactions with you.

Last I checked, the user could avoid OpenCandy by not including the Software Updater component when installing avast or by removing it later. Note that Software Updater is not the avast updater.

the other thing: The OpenCandy offers are not made, or not only made, during the installation of avast. They come when the Software Updater functions, as long as it is installed.

by sicknero on 24. August 2014 - 17:44  (118183)

According to Open Candy's own information, the OC component itself installs nothing on your system unless you accept one of the bundled offers. I've checked this for myself and it's true.

What happens is that when you run an installer that includes OC, the installer runs a dll which activates the bundled offers.

If you refuse all the offers then the dll is terminated and deleted after the original installer completes and nothing is left behind. I've also tested this for myself.

However, if you accept any of the offers then OC will install an auto-updater along with whatever offer you accepted.

The OC dll will "phone home" anyway, unless you block it, with the following information;

"A. Operating system version and language, country location and timezone of the computer running the installer, and the language of the developer’s installer
B. That the developer’s installer was initiated, and whether it was completed or canceled
C. Whether any third-party recommendations were made and if so, whether they were accepted or declined
D. If a third-party recommendation was accepted, whether the recommended app’s installer has been downloaded and the installer initiated
E. That the recommended third-party installer was initiated, and whether it was completed or canceled."

Note that the OC dll can be intercepted and blocked anyway, by programs like CIS.

by BroKen on 24. August 2014 - 21:50  (118187)

LOL. The link removed in the paragraph below because of the bad WOT rating was to OpenCandy's FAQ; accessed accessed 2011-03-27.

by MidnightCowboy on 25. August 2014 - 4:44  (118189)

Although you might like to think it's funny, our site rules are designed to protect visitors from potentially harmful links. Of course there are grey areas and situations when having a bad WOT rating does not present a hazard, but once we begin to make exceptions the whole system becomes meaningless. We do however expect members to read the rules before posting and abide by them for the benefit of the community. MC - Site Manager.

by BroKen on 25. August 2014 - 11:20  (118192)

The comic element was the entrance of WOT in this particular conversation, in a rebuttal of the claim that OpenCandy is benign. The opportune arrival of reinforcements. I apologize for the unclarity.

by sicknero on 26. August 2014 - 16:58  (118212)

I got the joke and enjoyed the irony too : )

I stand by my comments re; OC in general but fair cop, I hadn't properly looked into the situation with Avast in particular.

by BroKen on 24. August 2014 - 19:47  (118184)

Not sure why anyone would be comforted by the fact that the dll is removed, when (1) the snooping has already been done at that point, (2) it leaves a permanent identifier on the computer, what OpenCandy used to call a "non-reversible identifier" [link with bad WOT rating removed as per site rules], and (3) its dossier on you is kept remotely.

Thus it is, or was, FALSE that "nothing is left behind."

In any case, you are describing the typical case in which OpenCandy comes with an INSTALLER. This is NOT the case with avast.

The dll is in fact NOT removed in the case of avast (not that it matters). You may "verify" that via the avast forum thread linked above. It remains and gets triggered repeatedly by avast's Software Updater component (which is something akin to the Secunia Personal Software Inspector).

Sophisticated users can block OpenCandy, certainly, but those are likely not the users seeking recommendations for free anti-virus programs. Also, the presence of OpenCandy gives insight into the values and ethics of the avast company.

360 Total Security Rocks!

It's like McDonald's "I'm lovin it!"

Yes I realize it is new. I've been on the net since all the others were new also. I too like to live dangerously.

* Patch windows with Windows Updates.
* Built-In System Cleaner.
* Built-In Start Remover.
* Built-In Sandbox. (similar to Avast)

One of the best guis I have seen in a while since others mucked theirs up. You ever try changing the detailed settings in newer versions of Avast?

It might just be me but it seems my machines run faster with 360 Total Security on. Probably because of the patches applied. It seems to find patches that Windows Update did not find.

* I have not run it on a purposely infected machine.
* It did remove startup items I did not want removed. (They were easily restored)

I would recommend only for an Advanced user for now. We don't know yet if their system cleaner is going to destroy something important.

Seeing as my last post was deleted, because I dared to mention SERIOUS privacy issues with 360, check out this link.

by Chiron on 2. July 2014 - 12:32  (117091)

This seems to be just an assertion. This does not necessarily mean it is true. Have you found any other sources which back this up. I found many which linked back to this same article, but are there any which have reached the same conclusion through analysis of the product itself?


by MidnightCowboy on 2. July 2014 - 8:43  (117082)

Your other post was deleted because of the racist content. Implying that something Chinese, or from any other source for that matter, must be bad will not be tolerated here. MC - Site Manager.

by Chiron on 26. June 2014 - 1:48  (116927)

Thanks for providing this very helpful information. During my next re-write I will very likely be adding this AV to the article. It'll be interesting to see how it compares in tests.

Thank you.

by George.J on 24. June 2014 - 2:29  (116901)

I'd be using it, if my internet was faster. To update 3 engines takes thrice as much time.

by Bhat59 on 22. June 2014 - 16:35  (116875)

Few have commented on 360 Internet security and have told to wait until it is mature. I din't understand what it meant. I have already switched to 360 Internet security on my Windows 7(and also on my Android phone). Earlier I had Avast, AVG, Panda Cloud and Bitdefender. I liked 360 IS because it updates quickly. Also it doesn't install unwanted software during installation. I am also interested to know why it is not included in FREE AV list.

by Chiron on 26. June 2014 - 1:49  (116928)

I will be considering this AV for my next re-write.


by Kleepto on 11. June 2014 - 23:01  (116735)

Chiron how can we trust your review when many other sites rate Comodo very low and you stated that you are "a moderator on the Comodo forums" this seems to me to be a bias toward a product.

As a software developer i created 5 viruses for testing with and Comodo only detected 1 of them while BitDefender and avast detected all 5

How can you assure me that you are not biased

by Chiron on 12. June 2014 - 0:06  (116736)

I absolutely understand your concern, and it is one which I would likely worry about for others as well.

The difference between my approach towards rating these products and that utilized by other sites, is that I put protection first, and don't really care about detection unless it increases the protection. Most other sites put a premium on detection, which is not always a good indicator of the protection a product will offer.

Comodo Antivirus does not have the best detection, and as you mentioned Avast and Bitdefender do tend to have better detection ratios than Comodo. However, that does not tell you everything you need to know about the security product. The main difference between Comodo Antivirus and the others in the list is that Comodo Antivirus utilizes a default-deny architecture, whereas the rest utilize a default-allow architecture. What this means is that with Comodo Antivirus any unknown application (which includes all malware not already detected) will be partially isolated from the rest of your computer. However, with a default-allow antivirus all unknown applications (which includes all malware not already detected) will be allowed to access your computer.

Thus, I rank Comodo Antivirus higher than the others not because of detection, but because its ability to detect the user from real-world malware is much larger than the rest. Remember also that zero-day malware, which is what users should be most wary of, is not detected at very high rates. Thus, a default-deny architecture does provide significantly more protection, even though its detection rates may be lower.

Of course, the downside to default-deny architecture is that the same isolation will be applied to legitimate programs which are not yet trusted by Comodo. Thus, the user will have to interact with it more than they would a default-allow program. This is why I mentioned that my top pick for advanced or intermediate users is Comodo Antivirus. This is because it requires some additional interaction. However, for those who do not want a piece of software which requires much interaction my top pick is Avast.

I plan on making this distinction much clearer in my next re-write. I hope this explanation was helpful. If you still have questions I am more than happy to clarify/explain further.

Thank you.

by Kleepto on 13. June 2014 - 1:23  (116753)

You have not given me any reason to think that you are not biased towards this product and only told me things i already knew about comodo and I even created one of my viruses to target programs that Comodo trusted, I was hoping it would still check these but didn't appear too, maybe there is a setting somewhere that I missed to make it check these programs if there is how do I turn it on ?

Also how can you not rate cleaning as important i don't want to have to install another program to do the clean up if i get infected, i put 20 viruses on my comp and Comodo wasn't able to clean them up for me where as even Norman got half them removed and it is well crap not worth the memory it takes up

by Chiron on 14. June 2014 - 22:16  (116772)

Please do create a bug report for this vulnerability in this area:
of the Comodo forums. I can then better evaluate this there and, if it does turn out to be a vulnerability, forward it to the Comodo devs for consideration.

I believe that the architecture of any software intended to protect a computer is of utmost importance. Sadly, most free products which refer to themselves as Antiviruses do not utilize a default-deny architecture. If there are any others I am not aware of please do let me know. However, realize that this article ties my hands when it comes to products other than those which refer to themselves in the name as Antiviruses.

As for cleaning, I considered including that in the comparison. However, the truth is that if a product has already allowed the system to be infected I would recommend using multiple products for cleaning. No one product can be trusted to entirely clean a computer. Therefore, I do not include cleaning because my main focus is on prevention of infection, not in cleaning an infection which is already there. Perhaps I should update the article to make this more clear.

Thank you.

by MidnightCowboy on 13. June 2014 - 4:32  (116755)

These types of comments hold no authority at all because absolutely no details are provided. This is the very reason why Wilders forum now disallows posts about home made "tests" because they are meaningless. Please provide details of the code you are referring to, how the tests were conducted and on what system using our site PM facility to so that Chiron can pass this on the the Comodo developers. Once this has been done, we will be able to respond here correctly, but not until. MC - Site Manager.

by George.J on 13. June 2014 - 8:15  (116757)

Sometimes I'm concerned about lab tests too. I mean AV-Comparitives doesn't test the free versions of AVG and Avira, and compares it against the free versions of Avast, Panda, Forticlient, Qihoo, which is an unfair comparison. Infact Avira came out first in the latest results, but they tested the IS version, not the free one.

by Chiron on 14. June 2014 - 22:21  (116773)

Agreed, it is very frustrating. However, in order to try to introduce more impartiality to the review I stuck to using these reviews, which have stated methodology, and use only the results for the Free versions. Thus, I am not judging them with respect to each test, but over all three labs for the previous three times the Free version was tested. I also take into account AV architecture, meaning default-deny and default-allow, and use that in my recommendations. I use default-deny being higher, but less user-friendly. That is why Comodo AV is rated number one (as my main criteria is protection) but Avast is rated just after because of higher user-friendliness and detection rates.

If you believe there is a better way to go about this please do let me know. I went through a lot of ideas before I came up with this one, but I also realize that there are issues with it.

Thank you.

by MidnightCowboy on 13. June 2014 - 8:59  (116758)

I've always been concerned about reliance on test results when choosing an antivirus solution but at least with the reputable labs you have access to the methodology. MC - Site Manager.

by MidnightCowboy on 4. June 2014 - 9:56  (116613)

I've had the latest FortiClient running on several machines for a while now, one of which is mine, and everyone including me is very happy with the results.

It's getting good results from AV Comparatives and VB for those who follow such things.

Be aware that the update process will kill you if you have a slow connection, but it's no worse than a lot of others.

Also, the stated Application Firewall is disabled unless you are registered into their FortiGate system.

The parental control/web filter is truly class leading and the configuration options are many, allowing for a considerable amount of fine tuning if needed.

IMO in combination with WinPatrol and say ZoneAlarm free firewall for those who must use something other than Windows, this is an efficient solution. MC - Site Manager.

by Chiron on 4. June 2014 - 13:53  (116619)

Thank you for pointing this out to me. I will evaluate this AV and consider it for my next re-write.

Thanks again.

by MidnightCowboy on 10. June 2014 - 6:25  (116704)

The updates for FortiClient are on demand (manual) which won't suit everyone but if your habits are such high risk that you need updates every hour then IMO you should be using Linux anyway. MC - Site Manager.

by andrew1879 on 1. July 2014 - 6:04  (117050)

I switched to FortiClient a few weeks ago too. The signature updates are automatic.
By default the software itself will only display an alert when a software update is available, but there is an option in File > Settings "Automatically download and install updates". Note that this option does not refer to the signature updates--which are always automatic in my experience--but to FortiClient itself.
So far I think FortiClient is worth a look - high detection rates, fairly lightweight and needs virtually no user interaction. The web filter is a nice bonus too. But I would like an option to not install its VPN component because it's useless for an average home user and it installs unnecessary virtual network adaptors.

I'll need to take another look at this as soon as I have the time but the updates were certainly not automatic on my machine. Furthermore, the FortiClient 5 documentation (page 69) refers only to the use of the manual "update now" button, unless the software is being used in conjunction with their commercial FortiManager.

In the current version of FortiClient ( the UI has been changed so that there is no longer an "Update now" button. Version 5.0 also updated automatically for me though, except when my firewall (Privatefirewall) blocked it and needed some configuration to allow the various FortiClient processes.
