Full-Screen 'Microsoft Support' Scam? Escape and Clean Up

Loud warnings, locked browser, a phone number to call — the 60-second escape plus post-call damage control.

  1. 1. Don't call, don't click — kill the browser

    Microsoft never shows phone numbers in browser warnings. Press Ctrl+Shift+Esc, end the browser task. On Mac: Option+Cmd+Esc → Force Quit. Reopen WITHOUT restoring tabs or the trap reloads.

  2. 2. If you called: assume full compromise

    They likely installed remote-access software and harvested passwords and cards. Disconnect from the internet, call banks from another phone, and get a pro cleanup — this is now incident response, not a pop-up.

  3. 3. Clean and harden after

    Clear browser data, run a full Defender scan, change banking and email passwords from a clean device, and enable authenticator MFA. Then tell your team — scammers sell 'willing caller' lists to other scammers.
