What is the best firewall for Windows 7?

Its rule based. Its not a HIPs, it has no signatures. It doesnt need updates like most traditional AV's with HIPs and FW's built in.

 

outpost was best before that Sygate was my go to firewall until it was bought and sunk

 

As a dogged, stubborn, persistent user of Win7, I am presently using PCTools FW PLUS. However, I just gave Evorim a brief test run and was very impressed. I have it in my scope as a possibility because it includes Win7 & subsequent Win versions, PLUS it is CURRENTLY being vigorously maintained & updated.

 

Jetico 2 Free.

 

Dunno which one is a best but for casual home user enought can be NetLimiter
