well have used Kaspersky Anti-Hacker ..and frankly i was totally disappointed....how can pple behind such a great Av make a Pathetic product like this..
..during the 2 1/2 Months usage..all it did is notifying me about how it stopped helkern Attact from certain IP...where this attact is ment for machines with SQL server.......so i wud suggest go 4 NAV if u have loads of resources to spare...else u can try Sygate/zonealarm/Look n stop etc ....
