If you opened any of their pop-ups I can't help.
Once I got the pop-ups I couldn't do much of anything even in safe mode....except...
If you have Vista, hit the start icon on the bottom left.
Go to backup & restore system.
Follow the instructions that come up.
I got nailed on Dec 26 (Merry Christmas MFer) but restored the system to Dec 1.
It apparently buried the SOB. It takes a couple hours to run.
Good luck.
