I just keep on my old XP sp2 computer a sample of Comodo3Firewall Pro and after a month of inactivity I had to update it. It went good but took half an hour. It scans now your PC for nasties and offers you technical help to remove it for $79 US. Same old story about all the warning pop-ups you never get with PCTools Plus Firewall. It is the firewall I use on my new Vista PC. I only guess that for the same defense strenght I am less annoyed by my software, and I swear it kills an internet session real fast. So, without being a psychiatrist, I still wonder why people prefer Comodo. I have the answer:it’s free! 
Hi gdiloren,
But the future is for what is inside your avatar. We all are waiting for the new avast firewall to be launched and then we can combine the goodies of both avast av and avast fw. Wouldn’t that be really nice?

I still wonder why people prefer Comodo. I have the answer:it's free! SmileyEven free it's not for me. The Comodo dragon and my system don't get along together..... :( Comodo is also hard on system resources.
Hi bob3160,
I have Comodo’s and BoClean, it is good but rather heavy on the old cycles. I think it makes a mediocre XP a slow starter. On the other hand it is secure, checks all and everything, and for the paranoid it gives you something to contemplate on every now and then. I also wait anxiously for what avast has in store for us.

Hi Damien,
When the Comodo dragon turns the hare into a tortoise, then there is a problem… ;D ;D
I’ve banished the dragon to a distant land since I didn’t have the heart to slay it.
Yeah, well, I’m not a paranoid, life is easier without Comodo 3 Firewall Pro on my PC for that small much it gives you in added protection. :
I use COMODO FW and BOClean without problems. Well, when i start the PC, it starts slow. But after, runs like a charm.
I’m waiting for COMODO AV and AVAST FW. I’ll test them, and then i’ll choose.
God is with AVAST!!
