Computer Help and Support

This is a really common thing. Never, EVER call. You CAN turn your computer off - just unplug it if you have to. Start it back up and run your malware and virus software. If you don’t have any, or it’s not up to date, take your machine to a reputable and competent (i.e., not Worst Buy/Geek Squad, where computers go to die) IT person.

Most likely, it’s a browser scam. But you may have a real mess on your computer, so make sure you’re clean if actual threats.
