"Works Perfect" Best Internet Security with great updates and a complete firewall. No requirement

"Works and it's free" Once installed, runs quietly in the background. Update notifications are automatic. I feel safe knowing that the program is protecting me. Numerous false positives. Constant asking for confirmation to allow installation of software can be a hassle. Works well; is free, but false positives are numerous. Guess it's better to be safe than sorry.

"Not for Version 3 - Tries to Install Version 4.0" Nothing at all! This downloader does not install version 3.14 at all - it attempts to install version 4.0.Required uninstall of version 3, Then it wouldn't install, and prevented the re-install of version 3.14! As stated above this does not install version 3.14 - instead it attempts to install version 4.0!

"If you only want the Firewall, you're out of luck!" I have used the Comodo Firewall for years, without a problem. It was good. With Comodo Internet Security, it says you can get only the firewall, but that is not true. You still get the anti-virus. BOTH PROGRAMS SLOW DOWN YOUR COMPUTER--and you lose your roll-over feature. It no longer functions. Hey, Comodo, help us simpletons out! If I just want the firewall, let me have JUST the firewall! For the time being, I'm going to find another.

"Very good product for free." Excellent firewall. The firewall sometimes does not let certain games run on the computer.

Dependable firewall. I feel much safer being connected to the Internet with Comodo Firewall protecting my system. Beware of false positives when using this product. Constant warnings and confirmation requests slow down installations. If you surf the Internet and want an alternative to AVG, you might try Comodo. It's free firewall and anti-virus are dependable, but not perfect. They offer decent protection at no cost to the consumer and you are alerted to updates as they become available.

"This is the best firwall" Free or otherwise, this is the firewall you need. Easy to understand, easy to use and good at what it does. What more could I ask for? "Defense +" module is a bit too active.

"Best free firewall out there, anti-virus is decent" The firewall is the best free firewall available. You can choose whether you want the firewall/anti-virus protection, or both. None that I noticed. Must-have free firewall for your PC, and anti-virus protection is good, but not the best.

- Robust suite of software - Excellent firewall, good heuristics and HIPS - Relatively quick on-demand scan - Has made significant progress in a short period of time, and next version (v4.0) shows great promise - No annoying advertising - Average (at best) on-demand AV scanner - Awkward/unpolished UI - Very few formal tests of AV components and no apparent will be developers to rectifiy this - Pop-ups are puzzling and annoying for average user - Seems to forget settings at times Comodo Internet Security is based in the right mindset - to proactively protect your computer from zero-day malware, rather than tilting more toward a signature-based approach. Though it's been the trend for a little while to try to focus less on specific signatures for each variant and instead use heuristics and HIPS, Comodo goes a step beyond most free packages and combines a good anti-malware component (formerly BOClean) and excellent (if noisy) firewall to the mix. A good, integrated defense-in-depth solution is hard to find in the free domain, and I'm glad to see this fits the bill in one package. However, for all of these layers of protection, quality independent information about each component seems to be sparse. With the handful of fairly recent information ranging from fairly impressive informal tests by end-users to pretty poor reviews (even if they are Russian), more needs to be done to help prove Comodo's real-world capabilities. Though I understand Comodo's desire to wait for more accurate testing procedures as their approach doesn't translate well to the current archaic testing regimen, they need to mobilize some sort of third-party organizations to test the capabilities of these components in earnest before it can really be trusted. This, combined with the awful and cheap-looking interface (version 4 is as much a sidestep as it is a step forward) and flood of poorly-worded informational pop-ups, does make me often wish that Avira Antivir wasn't ad-supported. However, with v

It's free, that's always nice. I guess the secure DNS thing is good to use, right? Loads much quicker than Kaspersky Internet Security. They say its firewall is pretty good, and that's all I really care about. The interface of Comoda throws me off. Maybe because I'm using their secure DNS, but I can't communicate with my wireless Canon printer. I need to exit Comodo in order to print. I finally uninstalled and reinstalled it to be able to give up their secure DNS; I couldn't find how do it on their forums or anywhere. Sure, I's is stupid. I'll nip that in the bud right there. Now that I'm just using my "normal" DNS, the printer is communicating again, and everything is fine.

When I got it to work, it was fast and intuitive. See bottom line summary for details. See bottom line summary. Installed and ran fine on XP SP 3 at work, however it does not play well with other firewalls. Our company is using SonicWall and I got frozen starts until I logged in under a local admin acct. Then, it was fine. It acted as the PC's firewall while still connecting to the Internet, but I had to be logged in so that I no longer was in the company domain. That was my XP experience. Back home I decided to try it on my Vista Home edition laptop. I uninstalled PC Tools FW Plus and installed this one. Frozen start up ("Welcome" wheel and nothing for > 5 mins.) with no domain other than the default WORKGROUP is on my machine I booted into Safe Mode and disabled the COMODO service in the Services panel. I then tried starting up again in Normal Mode and got the same frozen start at "Welcome". I booted again into Safe Mode and uninstalled the Comodo Firewall. (Thankfully Vista allows this; in XP, you cannot uninstall apps in Safe Mode.) Anyway, I then rebooted into Normal Mode and "I got my laptop back" as one might say. I then reinstalled PC Tools FW Plus and I was back to my usual uses for the machine. Others may have had different experiences, but this one was mine.
