I have been using Comodo Firewall for about 5 days now and it hasn't given me any problems. I guess nudone that it's one of those problems that happen to people because of there setup - installed things, maybe hardware, previous installed things, etc.
It's quite annoying to be 'a (bad) statistic' when trying software/anything when you hear so much good stuff about it.
From what I can say of trying Comodo Firewall the last 5 days is that
it's very light on system resources - the interface/program it self is very fast (which doesn't look like it at all since it looks like it uses a heavy skin)
it's defiantly not for newbies - this is for sure.
it's really different from Outpost (which I like) - Comodo Firewall, is just a firewall - it does not have any plug-ins, so some one using Outpost may not like this if considering moving over to Comodo (or at least trying it), that is of course if you like the plug-ins at all and use them.
Any way I haven't really played with Comodo as much as I should before considering using it from now on. Guess I should do that very soon.
