Ahh, I see
Hopefully your machine will now stay clean of all those viruses and spyware now then. Make sure you keep norton up to date tho, allowing live update to check automatically if you can. You should have free updates for a whole year with norton anti-virus (if i remember correctly). Unless they've updated norton considerably since last time I used it (2003 I think) it wasn't designed to detect spyware so make sure you also run a copy of MicroSoft's Anti-Spyware or Spybot Search and Destroy or similar to keep you safe from those.
my norton antivirus is registered till 2008
