Download the following: A-aware.. Spybot search & destroy, and Ccleaner. All free. These will clean all dodgy stuff spyware etc. from your pc. Remember to turn OFF system restore whilst doing this, as people clean their puter.. just to let system restore put it all back by "restoring" it. good luck!.
p.s.
I found Norton to be cumbersome and slowed my puter, I'd give AVG FREE a try Works great.
