I tried Comodo. I tried Online Armor. I tried PC Tools. I tried Outpost. I tried Jetico. I always come back to Zone Alarm. Doesnt bug you. Doesnt slow your browsing down. It remembers rules and only asks you once. It has gamer mode just for me. The program control is so very simple. Just check off allow. I am using ZAAS actually. It can block known spyware sites which I have seen in action.
