Comodo Anti Virus Reviewed
Reader Buffet asked what my opinion was of Comodo’s anti virus program, and since I had not tried it, I decided to take it out for a test drive. The first thing I had to do was but my prejudices on the back burner. Last year I tried Comodo’s firewall which completely irritated the hell out of me, when the firewall shutdown my Internet connection. But that is another story. I also personally believe that AVG makes the best free anti virus program. So I entered into this review with an open mind.
I downloaded the Comodo software from their website which is a combo anti virus and firewall program and is about 45MB in size. During the installation you have the option to select just the anti virus or firewall software or both. I selected just the anti virus software. I installed the software on my test box which is a AMD dual core, 4GB RAM running Windows XP SP3. I installed AVG to make room for Comodo and to test it properly.
After the installation I updated the software and scanned my system for critters. Comodo reported my system was clean. I than checked out the Comodo GUI and found it intutive and very easy to use. I continued to oberserve Comodo anti virus for a week and found that the software is light on resources and did not slow down the system.
I am a FREE freak. When possible I only use free stuff on my computers. I believe that the free software are just as good, if not better, than their commercial counter parts. So I give Comodo anti virus two thumbs up. It is a definte alternative to the commercial products such as McAfee and Norton.
But is it better than AVG or Avast free versions? I don’t believe so. But it is another alternative to the paid programs that suck the life out of our computer systems. I’m going to continue to use Comodo anti virus on my test box for the next few months to evealute it further.
Comments welcome.

Thanks very much sir. So far, I’ve had similar results. The auto updater worbks well. No complaints from me, but it’s still comforting to have an expert opinion as well. Thank you again.

I’ve switched over to Comodo Internet Security (freeware) after being a devout user of AVG for a long time. Initially I used AVG and Comodo firewall together with great success but when AVG started having difficulties doing automatic updates and AVG started slowing down my system, I thought I would try Comodo’s antivirus which is included in their Internet Security product. So far I’ve had very good luck with Comodo Internet Security and in fact I have even started installing it on my customer’s systems. When I first started testing Comodo antivirus it surprised me when it actually found a couple of Trojans in my system that AVG had missed. Of course that seems to be the case with just about every antivirus program but still, it helped me to decided to stick with Comodo for the time being. Like you, I was skeptical if it would be as good as AVG but at this point in time I’m pleased with Comodo Internet Security.

I am currently running the Comodo firewall only – I turned the antivirus bit off because the pop-ups annoy me even more than Vista’s UAC! The firewall is good, however. For antivirus, I run Avast, which I love (auto-updates every 4 hours).

To Oliver – It’s been my experience that it is always a balancing act on how tightly to set up antivirus and firewalls. The pop-ups are almost as annoying as dealing with a Trojan so I usually tone down the firewall and antivirus prompts. I must admit that it does take awhile to figure out how to do it on just about any program you use, but once you figure it out you can usually get the pop-ups under control. It all depends on how paranoid you want to be with security. The more paranoid you are, the more tightly you will set up your security which means you will get more pop-ups. You can tone down the Comodo Antivirus program to where you won’t keep getting those annoying pop-ups.

Did you actually test it out to see if it caught any viruses or just basing the opinion on the UI?

Hello Anon,
You must of read my mind. Yesterday I had a friend send an infected email and Comodo stopped it.

i have been using comodo for a couple weeks now. as a gamer, i needed an antivirus that is not a resource hog. this is by far the best as far as what its taking up in the background. i use to run AVG, and Avira (and still put those on customers computers) but as a gamer, i think comodo is very good for what i need as far as performace. also, its nice because it has a 64 bit versiob which i currently run due to using XP 64. i had some issues with AVG and Avira. AVG would run 3 or 4 background processes. and, avira would update mid game, and alt tab me out of game. also, avira was a little trigger happy detecting things i knew were not viruses. comodo does not kick me out of game, and doesnt give me too many false alarms.
i hope they keep up with this product, it can only get better. lets just hope they keep it simple and clutter free.

I have been using Avast Anti-virus after discovering how reliable it was and Comodo for the Firewall. It was becoming more and more frequent that Comodo would cause the customers system to be blocked from the internet. As good a firewall as Comodo was, i had to replace it with a highly rated Online Armor Firewall. I wrote to Comodo trying to get a response to the issue with the firewall problem and have not received a response from them yet. I talked online with a support staff person, but did not expect to get a solution to the issue. The Comodo Anti-Virus was intriguing and would have considered it, but i was already using one of the best if not the best anti-virus program out there, with Avast. Avast has almost every time caught a virus during the initial scan, on customers machines, that McAfee and Norton and AVG did not. It is hard to change from that success. Avast goes on all of my customers machines for protection. With 35 years experience and growing i have learned a lot about bad software. Personally at this point my confidence with Comodo is minimal.

Hi:
I did extended watching on varies antivirus and internet security test videos from youtube from the famous tester mrizos whom is pc tech and test different products against 100s or malwares and etc to see which is solid. here is the link: http://www.youtube.com/profile?user=mrizos&view=videos. He also has a web site where you can read more on the products and test and e-mail him which is: http://remove-malware.com/.
According to his video tests AVAST , Norton and alot of antiviruses and security suits failed big time on cleaning and detecting malwares. Avira, GDATA, PCtool internet security and Comodo internet security wre among the few that passed and detected all malwares .
Anyway I was a long time user of Avira antivir since it had the best and highest detection in all antivirus tests but decided to use comodo internet security and was amazed it detected 34 malwares that the mighty avira antivir missed. Avira always had beated other antivirus products hands down in detection of malwares and now failed against the comodo antivirus. Anyway I am using it as of now and is great.
By the way check those videos from the link and see the tests of different anti-malware softwares for yourself and decide which is best.
Also a tip if you want to never worry about malwares every again then get a sand box like sandboxie, geswal (do an internet search and see why its the future of malware detection) and a hips application. For example I use sandiebox and comodo internet security right now and thats it. sandiebox for safe internet browsing and the comodo internet security for anything I download or install to scan.

I found that comodo av was very effective after testing it. This included disabling the comodo av and hiding some virus’s from eicar.org. Comodo av found the first two just through heuristic scan and the rest after a scheduled scan. Comodo in general is a joke. I have never seen software of a feather clash as with comodo. And I would vote for Avast AV over AVG. The same for me, If its free it’s for me..

In the virus.gr classification (10 august 2009) Comodo arrives in the 19th position:

It recognized 95.7% of the malware

You forgot to mention one important issue, which is actually the reason why I chose Comodo: it is also free for business use.
None of the other free AV extend their free stuff for commercial use…
