If System Restore could not restore your computer to a previous state, and you suspect that one or more restore points contain infected files or have had infected files removed by the antivirus utility then you need to turn it off then back on again. You will lose all current restore points but if they are corrupt anyway then it doesn't matter.
Right click [My Computer] [Properties] then click on System Restore tab.
Put a check in the box for Disable Restore on all drives.
Click apply, then Reboot your PC.
After the system reboots, navigate to the System Restore tab and turn it back on. Click apply.
Navigate to [System Tools] [Restore...] and choose [Create a Restore Point]
Provide a name for the new restore point.
Try and restore the new point just created. It should work properly.
