i have a good recommendation, download http://www.combofix.org/
- combofix, probably removes ANY virus..boot into windows not safe mode or anything of the such..go to that website and download it..save it as like 123.exe but not combofix because most trojans/viruses disable it. after you save it, run it and let it finish, may take ten minutes to two hours, do NOT open any other programs while running, your screen will flicker and the computer will act like its goign al funky, this is normal, after its done running it will clsoe and a log will pop up. This should fix your problem.
also system restore most likely will not work because half the time viruses infect your system restore files.
