Microsoft tech support scam: is that call real?
Editorially reviewed · Last updated June 16, 2026
Yes — this is a scam. Microsoft never calls you out of the blue about a virus on your computer.
“This is Microsoft technical support. We have detected a serious virus on your computer that is sending out your personal data. To prevent permanent damage, do not turn off your device. Please stay on the line so a certified technician can help you remove it now.”
Other versions you might get: A pop-up that fills your screen with a warning and a "support" number to call, an email "renewal receipt" for antivirus you never bought, or a follow-up call asking you to install remote-access software like AnyDesk or TeamViewer.
What to do right now
- Hang up. Don't stay on the line, don't call back, don't follow any instructions they give.
- Never give remote access. Don't install AnyDesk, TeamViewer, or any app a caller asks for — that hands them your computer.
- Don't pay anything — no gift cards, wires, or crypto, and never read out card or bank details to a caller.
- Report it. File at reportfraud.ftc.gov and report the scam to Microsoft.
- If you already let them in or paid, disconnect from the internet, run a security scan, change your passwords from a different device, and call your bank to stop or reverse the payment.
How to make sure it never bites you
If you gave a scammer remote access or money, act fast: disconnect the computer, change your passwords from another device, and call your bank now to flag the charge. Then lock down your devices so the next call gets nowhere — see how to protect yourself.
Help protect someone else
Scams spread because people stay quiet about them. If this could have fooled you, it can fool someone you know — a parent, a friend, the family group chat. Passing it on is the easiest good thing you'll do today. It's safe to forward, and stands on its own as a record for a bank or the police.
