Hi 126,7,
As Robontweb has said, that particular virus is safely tucked away in a restore point. By it's very nature a restore point is locked away from any program, in case you need to restore to a previous point in time. The only way to kill off the virus is to switch off System Restore, run your AV and then create a new restore point.
See
here for info on how to do this.
