never use windows firewall, its good for certain things but unprotects way too many things, use nvidias firewall since its not so bad, but id still recommend zonelabs or sygate personal since they are both more powerful
Kerio firewall is also good. I use Zonealarm but other firewalls have been good. The windows firewall will prevent most incoming connections but doesn't usually stop outgoing ones. The best firewall would be a hardware firewall router.
agreed it doesnt label your computer as a pc but turns it into a piece of hardware that hackers dont aim for i recomended those two firewalls because they're free, but if you have the money id say agreeing with addis, go for kerio, one of the best around
Well I have a router with a quite good firewall so I use Windows firewall. But I have checked and all of my ports are stealthed by my router, so it doesn't matter what my software does.
