Norton was on my hit list as well for being such a resource hog. However it was suggested to me to try norton 360 3.0. I can say I was very pleasantly suprised. It does all its own stuff when the computer is idle and stops what its doing when you sit down and move the mouse. Downside to that is you have to leave it going at some point to let it do its thing.
