Be very careful--this one just hit my computer yesterday, and we were told that it's a password stealing virus, very harmful, and works very fast.
I had to end up taking mine to Best Buy. I didn't even download any links--but, my anti virus software wasn't up to date as it should have been.
Also, they said if your computer is infected, contact anyone you do online banking and shopping with, as it has the possibility to record key strokes on your computer, thereby getting passwords.
I'll post back here once I get my computer back, and let you know what else they say, or how much damage it did.
