Are you sure you really got it uninstalled? I think they make those anti-virus programs indelible.
Which remeinds me, I was trying to fix my ability to view my torrents lately, and tried to remove my utorrent, the computer said it was gone, so I downloaded a new one, and funny, all the old settings I had on the previous download of utorrent were in the new one already. Sure, not there, right.
