You're right, Clinton. It just clicked the mousebutton on the computer while I was away and installed it with my unconscious permission... yeah...But seriously - all I knew was I'd left it running a search for 20 minutes, came back and closed it (and it'd been the ONLY thing running besides my firewall and net connection since startup), and when it shut down there was a popunder saying "Thank you for installing 3D Bubbleviewer". That was the last time the computer worked until we reformatted.
