Tech Support Scam Calls and Pop-Ups Explained
Launch library · evergreen read

A pop-up suddenly fills the screen with an alarming warning, a virus count climbing rapidly before your eyes, and a phone number to call immediately for urgent help. Or perhaps the call comes first instead, from someone claiming to be from a well known technology company who has supposedly "detected" a serious problem with your computer from somewhere far away.
The underlying goal in both situations is remote access to your device. Once you install the particular software they suggest, they can see your entire screen, move files around, and in the worst cases, quietly watch and record while you log into your own banking apps, believing the whole time that you are simply being helped along.
Real technology companies do not proactively monitor your personal device for problems and then call you completely unprompted out of the blue. A locked or frozen screen paired with an urgent phone number is a deliberate scare tactic rather than any genuine diagnosis, no matter how official the surrounding branding and language happen to look on screen.
If this ever happens to you, close the browser without calling the number shown, or simply restart the device if the screen refuses to respond normally. Never install remote access software at the specific request of an unsolicited caller, however calm, patient and technically knowledgeable they might sound throughout the call.
