It depends what you mean by "Restore PC". If you mean Windows built in
System Restore feature then no it won't contrary to what someone else
posted. If you have a Dell/ HP/Compaq/eMachine/Gateway or other large
OEM pc with an option to restore it to the factory setup then that
may. Some of them give two options, a full restore which erases
everything, and a repair option which doesn't. The repair option
won't remove a virus. The full restore option will. It will also
erase everything that is on the computer so make sure you have any
important data backed up first. e.g pictures, music, email,
documents, etc. In any case backup your data before trying to remove
the virus.
