many people who have norton will have the same. it is the most annoying, invasive and crappiest piece of commercial anti spyware around. they are false positives.
I've had it once or twice, and the second time i realized why I did without it and went to not having it!
Ever since I installed the second version, I've had a pop-up upon start up for the damn Norton system and I can't get rid of it (I googled it, but the way I read was above my head and I don't trust myself). I also got another pop-up that says "Rundll" and that won't go away either.
I hate Norton!!!
