But that is very likely not going to clear the infection anyway because SR only restores the Windows system files and it's rarely those files which are infected. Plus, the restore points themselves may be infected too.
The only sure-fire way of eradicating infections is to restore from a clean disk-image or perform a Factory Recovery (but back up your data first).
When you've got rid of the infection you then need to install some decent online protection software such as Comodo Internet Security which I use. I've never had an infection of any kind whilst I've had Comodo installed.
Whatever you're using now is evidently no good or your PC wouldn't have become infected.
