|system restore will NOT remove a virus.|
try safe mode with networking and download malwarebytes, update it and run a full scan removing all it finds.
We have no idea which virus you caught as you didn't say.
The only way to fix system restore is to turn it off and turn it on again. That will reset it but all previous points will get erased.
If you use system restore and a point does not work, you have to undo that restoration before trying another point.
