It appears to be a virus or spyware of some sort, which sucks because I'm guessing you can't even open your anti-virus software in order to scan? In any case I'm stumped. Do you have Windows Defender? Programs like that often run automatically in the background so you might have a chance of catching it with that. Otherwise fiddling with the registry would be an answer, although those
windows might even be closed, so the only other advice I have is to call a specialist.
So sorry I have no other suggestions
