i don't know... i just know i clicked on a link to that site from google (and firefox was the only program i had running and that was the only thing open in it) and the yellow bar popped up in firefox saying firefox prevented the site from installing spyware and then some "TSA Installer" appeared in the system tray... and when i killed the process the machine blue-screened... it took me half an hour to get all the junk off that machine... and i know none of it was on there before because i just reinstalled windows the day before and the computer was not used at all until today...
