Also, download Spyware Blaster from the Dream Machine IBox. It doesn't actually run per se. It sets kill bits that cause trojans and worms to think they have already been installed so they don't install themselves again. Neat little program. Updates out weekly.
cintrix, I've run Gibson's 'leak test'. All it does is try to access his site from inside your computer. A good firewall like ZA will prevent that. A hardware router alone won't - as far as I know. You need ZA!
