Come on buddy, what are you doing with a guest account on?? NEVER, NEVER keep a guest account. Guest and Administrator accounts should be disabled or at least changed names.

What are you doing without a firewall?...

Anyway, you can buy a firewall... I've had good experiences with Sonicwall, or make one yourself with an old box, linux, and a couple of NICs...

BTW, hello again guys, I'm back in antionline after a couple of years!
