Pkot Hi.
Your problem was that a worm had enterd the back door of norton and made
changes to how it works, I suspect that if you installed 360 straight over the
top of the old norton, you may still have a problem,
You can get a Brute Force Uninstaller from nortons website made by them to
completly remove all norton files from regestry & memory.

P.S..Anyone that Has no C.D.for reinstall should coppy Norton installer App to
desktop before uninstall. People with a cracked copy of norton, Put it in the Bin, it will never work propaly.
Peace.
