I have been Trojanned!!!

and I wish I could say it was in a good way . My question is that norton apparently blocked it since they are supposed to put porn sites in my favorites and reset my home page to something else and none of that has happened. I ran a full norton scan and it found 4 viruses, but said it quarantined (but could not delete) 2-nothing about the other 2. Ran spybot and CWshredder and deleted everything. Also deleted all cookies and files (the button right next to the delete cookies button). I read on norton's site that I had to turn off system restore in windows XP, but even though i was logged on as the administrator, there was no system restore tab (is it different for windows XP home and windows XP pro?).

ok so that is what i have done, my question is, am i safe now? are they gone? or is my computer still vulnerable? I read on Norton's site what each on supposedly does to you computer and none of it has happened to mine. Any thoughts? this is my home computer. Thanks!!!!
