I run Zone Alarm as one of my firewalls, I also run the one built into win XP, and my third firewall is inside my wireless router. I also run Norton Antivirus Corporate edition. (I got this from my college for free) I also have the cleaner, which is a program specialy designed to remove trojans. I have almost no pop-ups, and any spy-ware can't comunicate with the internet, because of the firewalls.
