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 
1. What is voice changer software?
2. Does your wife know about your bitcoin? Is it possible she is involved?
3. Did your run anti-malware and virus scanner software after the loss?
