Its funny how the three of you posted the same link...LOL, shows how much you read each other's posts. Anyways, Al1, you dont have to download somethign to get spyware. Just visiting certain sites, will infect you or if you get too many popups from a website, they might install something in you PC. Warez sites, porn sites, anything illegal sites are infested with these. Not saying that you go to those sites, but even the innocent looking websites can carry spyware.

Hope this sheds some light onto your problem. And, yeah....follow the advice given to you on how to remove it.

Cheers,
