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 
Sorry for your lost OP. That number of bitcoin should be kept in a hardware wallet or in a cold storage wallet and not on an online wallet. Next time don't share your computer or phone that you have your bitcoin wallet in with anyone even with your wife, because you might understand how you watch and restrict your activities online but the other person might not, and it will make they will make you vulnerable to attack from what they intend to do with your PC. This is a sad news, you have learnt a hard lesson to keep your coins from online wallets.
