What is Kaspersky Anti Hacker?

[PhiloVance]

It's somewhat explained here (http://www.kaspersky.com/antihacker) but I still don't know if I need it. Running Windows XP Home with NOD32/Kerio.

It's a personal firewall. Since you already have Kerio installed, you will be covered in the firewall department, so you don't need Kaspersky Anti Hacker.
