Ick... this has been one bad month with this infection!
I got infected with Gromozon (aka linkoptimizer) rootkit last month and it has been nasssttyyy... slows down my comp, makes popups...
I recommend to anyone who is having a slow comp to try the removal tool http://www.prevx.com/gromozon.asp
it is free, and really gets rid of the infection very quickly (needs to reboot but it does it all fast)
Good luck guys! And Cheers!
