Hmm, makes me think of a remote admin tool, with the way your screen went (that and an infection notice coming up). Maybe try one or two more freebie virus checkers as someone could have trojan'd you with that tool. If nothing comes up check your quarentine logs in Norton, noticed it will sometimes sequester a virus automatically then *hide* it, very frustrating though only has happened once, thought I was seeing things. If you still find nothing, then your probably good and it *could* have just been the worm trying to infect your comp and you have no worries. Though if it happens again (hopefully not) then post here and I can point you to some more intrusion detection, packet sniffers, etc etc that will at least source what's happening by logging it.

PS. don't worry bout the pcanywhere, was just using it for a reference/example to see if it was like that.
