System restore has disappeared

If none of the above suggestions worked, then:

1- Run your Antivirus app.

2- Check for updates
- Start menu > type Updates in the search bar
- or simply go to the following website: http://update.microsoft.com

3- If prompted, restart the pc
- Check in Start > All Programs > Accessories > System Tools if System Restore appears.

IF NOT

4- Check this forum for further advice (referred to XP, but still applicable on 7 as well):

5- If still unsolved, then I 'm afraid you might being experienced a serious virus threat.
