Talked to my wife. She tried to install a voice changer software yesterday from a link on twitter and it didn't install. This is a windows 11 PC. I see something new called WingFtpServer as a startup program. That has to be it. C'est la vie 
I'm very sorry for you, I can't even image how you feel right now. I don't store any bitcoin information on my computer but if I were, I would never let anyone use it, not even to check his/her Facebook or email. A friend of mine lost a few bitcoins because his mother used once his computer, I don't remeber what se did, I think she clicked on some link she wasn't supposed to and they stole everything.
