There are some real baddies out there, folks who can and will turn your hard drives into jumbled nothing until you pay them hundreds of dollars. Protect yourself with offline backup. There are many free alternatives out there, including iDrive, Opendrive, and Google Drive. Syncthing allows you to back up to a friend’s computer, another concept of cloud storage. So there’s really no excuse for losing your files any more. If you need help getting started, contact me.
