Major problem with my computer. Need help!

I have just apparently gotten a really bad virus and I don't know what to do.

It has these features:

-It makes startup for the computer extremely slow; when I click login as admin., it goes to the background for 1-2 minutes before the icons load. This never happened before.

-Surfing the internet (with firefox or internet explorer) leads to tons of pop-ups.

-I cannot do a system restore to any day before today.

-I was not on the computer when this happened. My brainless friend caused it while she was looking at some website (she won't tell me exactly what it was).

-Ad-aware didn't remove it.

I want to know what type of virus it is, and how to remove it.

Thank you.

 

I really am not a computer expert, and I have tried many of the tools at my disposal, to no avail.

If I could understand what type of virus/malware/whatever is on my computer, it would make my life a whole lot easier, because I would be able to target it with a specific program.

Thank you for your time, I really am lost here.

I put up SAS and it practically crashed my computer...I don't know if that was due to the virus.

Anyway, the virus ironically downloaded some anti-spyware (or maybe an anti-spyware lookalike) that pops up when I go on.

I don't want to run Mbam because it could cause the same problem.
