Tech-Support Scam

A pop-up says my computer has a virus and to call Microsoft, is it real?

By Grandma Pearl · Updated June 2026 · 3-minute read

No, sugar, that screen is lying. Microsoft doesn't lock computers or put phone numbers on warnings. Don't call. Press Ctrl + Alt + Delete, open Task Manager, and close the browser. Pop-up gone, computer fine.

▶ Pearl's quick take (AI-generated). See all shorts →

You're reading your email when, bells! sirens!, a big red screen takes over: "VIRUS DETECTED! Your computer is locked! Call Microsoft at this number RIGHT NOW or your files will be deleted!" Maybe there's a robotic voice, too, just to get your heart going.

Take a breath, dear. It's all theater.

Why it's fake

Microsoft does not lock your computer. It does not put phone numbers on warning screens. And it has never once cared about your cousin's casserole photos. That pop-up is just a web page designed to look terrifying so you'll panic and call.

What happens if you call: a friendly "technician" asks to connect to your computer remotely, pokes around, shows you scary-looking gibberish (it's harmless system text), and charges you hundreds of dollars to "fix" a problem that never existed. Worse, while he's in there, he may quietly peek at your bank login.

Pearl's fix, make it vanish

On a Windows computer: press and hold Ctrl + Alt + Delete together → choose Task Manager → click your web browser → click End task. The pop-up disappears.

On a Mac: press Option + Command + Esc → select your browser → click Force Quit.

When you reopen your browser, if it asks to "restore pages," say no, that would just bring the nasty pop-up right back. If the thing keeps returning, restart the computer. Still stuck? A real local repair shop, one with a door you can walk through, is your friend. Never a number from a pop-up.

If you already called or let them in

It's alright, honey, they're good at this. If you gave them remote access, unplug from the internet and have a trusted local technician check the machine. If you gave any payment or bank details, call your bank, change your passwords from a different device, and report it at reportfraud.ftc.gov.

More from the porch: What is a family safe word, and how do I set one? Is the "USPS package fee" text a scam?
