Sometimes, almost rarely, command prompt screens began to appear and now, out of nowhere, I see a shortcut of an Adobe express photos on my desktop. When I went to open the file location, I came across so many files that I've never seen in my life, even dated more than a decade ago (I've had the computer for a maximum of 5 years, bought it new). Am I mining bitcoins for someone ? What could I do to fix the PC?
