This is beginning to escalate. Now there is a viurs involved.
Believe me, I understand your situation, you are not just playing games online, your computer is essential for your work.
With a virus involved in the restore files, this becomes more difficult to solve.
The only thing that I can suggest at this juncture is to post in the security forum and try to get rid of the virus.
You can keep this post and possibly you will receive some additional help that will assist you in the short term, but that virus must be eliminated.
I will keep your problem in mind and post whenever I come up with an idea, even if the chances of success are limited.
I wish you the best luck with your problem
