Point being, you suspect that a virus messed up your system restore, therefore, until we can safely believe that the system is clean, we can't really try and fix system restore.
This would be 'my' first step.
My son was on the internet and I think he downloaded a virus or some other malware. I have avg running and its not showing any viruses, but i can no longer use my system restore.When I open it up it says "no restore points available", and you can not select any dates. If anyone could help me out it would be appreciated alot.
