Introduction

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:

10/6/2014-Major revisions, re-ordered two antivirus products, and added an additional product to the review.

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.

 
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:

AV-Test

AV-Comparatives

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.

 

 

 

 

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. 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.

Comodo Antivirus
5
 
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

Avast! Free Antivirus
5
 
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.

There is some antivirus which slows down PC a bit as it uses more resource in your system while some don’t. Norton, MSE are such type of antivirus tools which will slow down your system. Immunet Free, Avira, Bitdefender etc. Are some antivirus which does not have much effect on computer speed and performance. Every antivirus tool automatically updates itself but you need to check automatic update box in software’s setting.

I personally use Immunet Free, here is a free download link to it - http://www.immunet.com/free/index.html

Not sure why Avast is at the top, even though Webroot clearly is lighter from the tests and is regarded to be the lightest antivirus of all time, both in terms of installation size and while idle/scanning..

by windyctyprog on 17. May 2013 - 16:45  (107811)

I have decided to change AV software and leave MSE behind.

I've had on-going Windows Genuine Advantage issues when MSE tries to update - every morning this week when I cranked up, I got the warning that I have to reinstall the WGA plug-in for Firefox or MSE won't work.

Regardless of the issues, it's time to leave...

So, a question:

Is it better to go with a new stand-alone top rated AV, or maybe move to a Zone Alarm suite?

By way of a little background on my schema now:

MSE running in real-time

PrevX 3.0 running in real-time

On Demand: Malwarebytes, EmsiSoft Malaware, Hitman Pro 3.7

I have used PrevX since their introduction and like it, so I would like to keep it going and obviously need something compatible.

Thanks, in advance, for your thoughts and input...

by George.J on 18. May 2013 - 0:05  (107818)

I take back my words. I found that Avast flushes memory every 10 sec so the memory consumption will always be back to 5MB during scans (and never above 20MB), which I think is a great feature.

by JonathanT on 18. May 2013 - 1:54  (107820)

I firmly believe with a bit of common sense and safe practices you will be safe with a good free AV (any of the ones listed here). I think it's also important to note without those two things, the best paid security suite wouldn't fully protect you either. You have more than enough on-demand scanners as well. :)

by JonathanT on 18. May 2013 - 1:57  (107821)

Thanks for the heads up!

by AJNorth on 18. May 2013 - 3:35  (107822)

Neil Rubenking has published an article in PC Magazine that some may find worthwhile, "The Best Free Antivirus for 2013" (2013.05.08) -- http://www.pcmag.com/article2/0,2817,2388652,00.asp .

by supanut on 18. May 2013 - 5:14  (107823)

After my try with Avira, I am now considering whether I should change my AV. I like MSE for its non-intrusiveness, but the new versions rarely get released. Avira, on the other hands, has new versions more often, but it may have some annoying popups that I may not like too much.
I'm on a core I5 with 8GB RAM, Windows 7 Ultimate X64, and MSE didn't seem to eat too much resources, but I've heard from some of the comments that Avira doesn't use up as much resources as MSE.

by GizmoJr on 21. May 2013 - 1:01  (107912)

I wish to praise all of the writers on this site. You have a very tough job. because there are people that don't agree with you. Then you have to put up with the criticism of those that don't agree with you. Like me........LOL You all do an awesome job.
Now for my criticism...LOL MSE has really fallen in there detection rates, I have run MSE on my system, and then ran all of the others behind it, to see what it missed. Every time I did that, it had missed something. Ease of use, does not make it a good anti-virus. I rank Avast as the best. That is a good call. It is just too much advertising for my taste though. From my testing, I would rank Avira number 2a, then AVG number 2b. I use AVG on my system. The reason I do is the ability to configure AVG to do what I want it to do. When I configure AVG to do a scan my way, it out performs all of the others. Panda is solid at number 3. MSE comes in at number 4. But MSE has become far to passive for me. At this point MSE does not even make it on my list.
If I could teach people how to configure AVG to scan my way, it would be number 1. God Bless you all for what you do!
Now for a request. It would be nice for this site to give a little lesson on how to use Task Scheduler within windows. I use it for so many things that do not have scheduled task within their programs. Examples : AVG does not auto update enough for my taste, so I use the task scheduler to do more updating. I also use it to run Ccleaner on a schedule. I think you would be doing the visitors of your site a great service, to teach them how to use the Task Scheduler within windows.

Thank you ALL so much for what you do!! I LOVE you all!!

by MidnightCowboy on 21. May 2013 - 1:30  (107913)

It's a risky business looking at the various test results and then choosing an antivirus based solely on them. I'm in regular contact with many users of MSE, some in a businesses environment, and none are getting infected. The fact is that if your surfing and general PC usage habits are "infection prone", then you will be sooner or later no matter which security products are installed. It is also only of benefit to the community if you provide details about the "something" MSE supposedly missed, including the file path, and/or if like many Windows users, you have UAC disabled. :)

MSE is designed to work as an integrated solution alongside other Windows security services so it will always give weaker results when tested as a single entity.

In theory, MSE will always perform at a lesser level, especially where heuristic detections are concerned. There are however so many other ways to avoid zero day infections that blaming your AV for this is a poor option.

Certainly for the more tech savy, a program such as AVG offers the possibility for greater overall protection. This can also lead to a false sense of security however for the reasons stated above. For average users though who have only basic PC skills, MSE remains a solid choice for it's simplicity when employed with safe surfing practices.

Also, browser extension choice IMO plays as important a role as choice of AV and/or firewall.

by GizmoJr on 21. May 2013 - 2:30  (107914)

MidnightCowboy you are absolutely correct.

But if I were to give you all the technical aspects of how MSE fails on so many levels, it would take up this whole page and more. It is a mistake to disable UAC. Do NOT do that. I confess that I am not an average user. My rating system, that I gave, took the average user in mind. Otherwise, I would have put AVG as number 1. My parents are average users. They don't even know what a file path is. They have a false sense of security, because of their lack of knowledge about the Internet and the computer that they use. Every time I go to there house, I have to go through a whole cleaning process of there computer. They have one antivirus, I have six. AVG being the main one, then five scanners. AVG is NOT perfect, but none are perfect.
My point in responding , is to educate the average user without overwhelming them with to much of the technical aspects of using an antivirus program. But also to inform the more technical user of what might be a better choice.
I would advise anyone surfing the net to never feel secure. Just learn about the tools you are using to protect yourself.
MidnightCowboy, you are the best of the best. All my respect goes to you.

by MidnightCowboy on 21. May 2013 - 4:18  (107915)

Thank you for responding. You are correct that our comments sections are reserved for just that and we always request more in depth discussions and other data to be posted in the forum. Many of our editors, including myself, do have direct contacts with vendors however and are more than happy to follow up information whenever possible. Please do post your scan results in the forum and we will then attempt to find out why MSE failed to detect them.

by JonathanT on 1. June 2013 - 12:03  (108197)

Thanks for the link, always appreciated!

by JonathanT on 1. June 2013 - 12:05  (108198)

Avira generally is lighter on resources than MSE, but I don't think it's a major concern with your computer. Using frequency of versions as a basis for judging AV's is probably not the most reliable. :) If you find the pop ups too intrusive, Avast or MSE are both good choices.

by Rolandkeys on 2. June 2013 - 16:45  (108219)

Thanks all have got Avast 8 working fine with malwarebytes free and zone alarm firewall

Re: Avast (not sure the correct section to post this)

Affects ADSL connection, tested a few times (uninstalled/installed)

Prior to install - http://speedtest.net/result/2765784164.png

After Install - http://speedtest.net/result/2765790646.png

No such issue with MSE

Update! After many attempts, searched solutions etc, for some reason I'm now not able to reinstall MSE, Grrr
Error Code: 0x80070643

by rroberto on 18. June 2013 - 12:31  (108579)

Of course it's asking for trouble to install 2 or more AV apps. But it can be done safely if one can be set to run in real time, the other to run only on-demand, as a cross-check of the realtime app.

I currently have Avast Free as my real time AV (quite happily) and Avira AntiVir on-demand because it has very strong detection rates with few false positives. But Avira's nag pop-ups are unstoppable, even after following many "proven" methods for getting rid of them that one can find on safe 3rd-party sites.

Now my questions. If I update Avira from AntiVir to the 2013 Personal edition:
a) can I still set it to run non-resident/on-demand only?
b) will the pop-ups stop?

by Fixer_MED on 27. June 2013 - 21:56  (108761)

a) Yes. You can disable the Real-Time Protection option in the main window.
b) Only the update/virus found pop ups. You can disable most of them in Options(Extras/Config/General).

I'm using Avira Internet Security 2013 13.0.0.3640, by the way.

by godel on 4. July 2013 - 22:14  (108981)

Anyone considering AVG as their antivirus program of choice should read this article from earlier this year regarding malware-like behavior from an AVG product. The associated comments provide a number of solutions to the problem.

http://dottech.org/101609/avg-secure-search-toolbar-is-malware/

I also believe AVG has slipped down the ranks in the ratings of the testing authorities such as av-test and av-comparatives.

by Burn-IT on 9. July 2013 - 11:12  (109072)

Can you add a warning about Avast.
It tries very hard to install Chrome browser on install. You only get the option NOT to on Custom install
It also sneaks an attempt after restart after program update (this one has caught me several times)

by George.J on 9. July 2013 - 14:52  (109075)

Many freeware programs have their installers like this, where they try to sneak in the adware, and this is where Sandboxie and Winpatrol comes useful.

by Burn-IT on 9. July 2013 - 15:09  (109076)

That is NOT what I expect from an AntiVirus product though.

Sandbox av??

by MidnightCowboy on 9. July 2013 - 15:52  (109077)

I think George.J makes a valid point irrespective of the software type and especially where something as expensive to maintain as an antivirus product is concerned. These costs have to be funded somehow and vendors will use whatever means to do so whether end users find these sneaky or not. Also, the rise of this program type from countries such as Vietnam where costs are considerably less is putting further pressure on American and European producers in a highly competitive market.

We try on a product by product basis to advise about wrapped installers and bundled toolbars but these are almost impossible to keep up with as vendors tend to swap and mix components regularly.

In the end though the addition of WinPatrol will help users to avoid most of it as will a simple Google search of the product name beforehand followed by "toolbar bundled components". This will forewarn users about what they are likely to encounter and enable them to take the necessary steps to avoid it. MC - Site Manager.

by Burn-IT on 9. July 2013 - 16:12  (109078)

I don't mind the attempt at inclusion on install, that one expects.

But having declined, I do think it is extremely immoral to allow automatic updates and to say restart to finish install and then sneak it in again on the notification of completion screen after the restart.
If you just click to clear this message ! BANG ! you get Chrome installed and set as default.

by Anupam on 9. July 2013 - 16:52  (109079)

Yes, that is sneaky, and users have raised this issue over there in Avast forum too. That's why I avoid updating from within the program. I download the setup and then update it.

Would also like to point out that home page change, startup entries, toolbars, etc. can be avoided by WinPatrol, but not these installations like Chrome with Avast. Also, you cannot install an antivirus in Sandboxie. General users avoid Sandboxie anyways.

by Sahil Waste on 12. July 2013 - 13:45  (109167)

Hi JonathanT,

Can you please share your views on Bitdefender free and Immunet free with me. i want to know how good they are.

thanks :)

by cavehomme on 12. July 2013 - 21:35  (109180)

Another "warning", and I've tried Avast on and off for at least 10 years, is that it is surprisingly resource-heavy. The latest releases during web browsing are especially slow.

by George.J on 13. July 2013 - 2:13  (109183)

Really? Avast came out as the lightest antivirus among the 20 products that have been tested at Raymond

Memory Usage Test to See Which is the Lightest Antivirus Software

Although there is no CPU usage considered in the tests, I wouldn't be surprised even if it was low. Avast is a lightweight antivirus.

I've no slow downs while browsing too, but if you feel there's any slowdown, you could disable streaming and reputation services. I have switched it on and my web browsing speed is normal.
