Okay a list of things kinda came up ALL at once, if anyone knows about XP's ridiculous structure please help!
Norton recently found a virus installed on my computer and deleted it but here are the after affects:

Running Processes:
There's 50 Running processes right now which is WAAAY too much, last week i only had 40.

One program not working:
I use iTunes a lot and for some reason it just won't open. I did Start>Run the works! And it's running on my process box but there is no other signs of it on my computer

Not shutting down:
I click Start>shut down and nothing happens, except Norton closes and that's it.....very strange

anyone got a good program or some way to help me clean up my computer? Or anyone face the same problems?
