Comodo Firewall Pro is the best firewall that I have found so far.
It has earned a "stealth" rating at Shields Up and has been easy to use.
It has an Application Monitor,Network Monitor,Component Monitor,and Application Behavior Analysis.
The early versions of Comodo were heavy on resource usage. Comodo listened to the complaints and made subsequent upgrades lighter on resources.Very responsive developers for freeware!
This is version 188.8.131.52.This firewall has always been rock solid with no conflicts of any kind.
Version 3.0 is in beta and sounds promising too.
I have tried LookNStop,Kerio,Bit Defender,Sygate,Zone Alarm,Filsec,and a few others and I would take Comodo over any of them!
