try to find out what the name of the virus is

Norton can usually give you the details

form there you can do some research and find ways to remove it

try emailing Symantec (the company that makes Norton, on another computer maybe) and give them as much detail as you can about your problem

they will give you further advice on what you should do

if you cant remove it then your only option is to wipe your hard drive and reinstall windows
