If your PC is running windows XP or newer you should reboot the system into SAFE MODE (with NO NETWORK) as the administrator.
Then use the system restore to restore your system to a time before you acquired the virus. Hopefully, this virus did not delete the restore files and this method will work for you. If your restore files are gone, there is a free program called RECUVVA which will hopefully reinstate the restore files. Again, you will need to reboot into SAFE MODE as the administrator and then run recuvva to reinstate the restore files. Then, while still in safe mode, restore your system to an earlier time.
Good luck. This works for the majority of viruses that are out there but it will not work for the truly nasty ones.
Good luck.
