computer security

A lot of people like Comodo's free software. I use it on some of my computers.

I'd like to add that that's probably not true nowadays. Comodo firewall used to be the best free software firewall on the market, but just like ZoneAlarm, AVG, and scads of other free security software out there they let their success go to their heads.

The latest revision of Comodo Personal Firewall (V3, I think) was a shambolic mess that refused point blank to remember firewall settings, hogged resources like a fat kid at a cake table, and was singlehandedly responsible for my last system format/reinstall.

Basically, on an automatic update of itself, the firewall decided that a certain file was a danger to my system and decided to forever deny it access to my OS. The problem was that this file was a core Windows file that rendered the machine unusable. Couldn't connect to the 'net, couldn't open Explorer windows, couldn't access the Start menu. I located the file being blocked in Comodo and attempted to unblock it, but it refused to. Couldn't run any Control Panel applet, couldn't uninstall Comodo, couldn't even bring up the Task Manager or kill processes.

And to make things worse, I couldn't even boot into Safe Mode to fix this. Comp was essentially bricked until I could wipe and reinstall. Thankfully, this is why I never keep anything important on the main Windows partition. Still had to reinstall WoW though.

Comodo might have improved back to the standard it once was held at, but pretty much anything that kills a computer in such a blunder is instantly blacklisted to me. Would never use another Comodo product again. A--.
