CRITICAL tech support
Microsoft / Apple security alert pop-up asks you to call a number
A full-screen browser pop-up or audio alarm claims your computer is infected and shows a fake Microsoft or Apple support number. If you call, the "technician" asks to remotely access your device.
Also known as: tech support pop-up scam, browser locker scam, Microsoft support scam
What to do right now
- 1 Do not call the number on screen — close the browser with Alt+F4 (Windows) or Cmd+Q (Mac)
- 2 If the browser won't close, restart your computer by holding the power button
- 3 Do not install any software the caller requests
- 4 Run SeraphSecure (https://www.seraphsecure.com) to detect and remove any remote-access software the scammer installed.
- 5 Report to the FTC at https://reportfraud.ftc.gov and the FBI's IC3 at https://www.ic3.gov.
Was remote-access software installed?
If a scammer asked you to install AnyDesk, TeamViewer, Quick Support, or any remote-access app, your device may still be compromised.
