I suggest you do a full reinstall of the operating system, using the recovery discs supplied by the computer manufacturer if you have or can get them.

Download this virus remover from here http://www.superantispyware.com/ If possible it is recommended that you load SAS in normal mode but run it in Safe Mode. Safe Mode can be started by continually pressing F8 during the boot sequence. If you are badly infected you might need to run SAS more than once to help clean your system. Afterwards if the only infections now being shown are in System Restore, once you are completely satisfied that you can boot normally, you can either delete the infected restore points manually, or temporarily turn off System Restore to purge the files.

Make sure that you have a good anti virus and anti spy ware program installed on your computer.
