"I think it was the Shockwave Player update I downloaded and had an option for Norton PC Checkup, I did the checkup thing and used it’s uninstaller which worked, But every time I restart my computer it opens and downloads again. I have used the built in uninstaller and windows remove programs. Do I have to find the directory on my hard drive to delete it? Anyway Norton Anti-virus is acting like an annoying virus itself!"
