Kaspersky Anti-Hacker by Kaspersky Labs eliminates common firewall woes with their anti-hacker control panel. Though the design is simple, this firewall lets even beginers fine-tune protection settings.

The application rule setting feature is easy to configure.

Kaspersky Anti-Hacker can stealth (hide) your identifying computer and ports, block Trojans (dangerous software) and exploits (attempts to steal your data)

On top of that it's low on system resources which is very important if you are a hardcore gamer or u have a PC with low memory. On my machine it's taking around 400KB while most firewalls consume 18Mb or so... So better check it out!
