I shut down all my blockers/firewalls/ scanners and looked at it with "I'm a bonehead" security settings with explorer and didn't see anything.
Try using these three free programs
Spyware blaster ( real time keeps it from being installed/downloaded)
http://www.javacoolsoftware.com/spywareblaster.html also check out ther windows media play script fix to keep it from opening new windows
Spybot ( cleans your infected system)
http://www.safer-networking.org/
or adaware( cleans your infected system)
http://www.lavasoftusa.com/
All three will need to be check for updates when download and weekly just like you virus protection program.
The advantages of using these programs are your computer will become more stable, you should get increased speed and you won't have you resources stolen from you. They try to say you agreed to install all that crap, maybe you did to some
but not all. Its like that line you opted in to every piece of spam you get.
