Norton SUCKS, period, okay?
What does a nosey dog have to do with anything though?
Who put it on there anyway, your parents? If it's your computer, go and find some good antivirus program (Microsoft Security Essentials is good, AVG antivirus free does well in stopping, blocking, and catching viruses, even has a free linkscanner) and grab a free Anti-Spyware to grab the stuff that the antivirus misses and antivirus programs don't always catch or clean tracking cookies.
If it's a computer that is shared by the household, talk to your parents about it, give those examples you just gave.
@Bla, har har, you're not helping dude..... (other than the point that Norton sucks)
