  • When a “Microsoft” alert hijacks your screen after a spoofed Facebook call

    Tech-support scam pop-up mimicking Microsoft Defender with a bogus support line 877-415-4519DO NOT CALL.

    Intro

    Tonight’s “video call” looked like it came from a friend. The moment you tapped Accept, your browser flipped full-screen: “Microsoft has shut down your internet. Do not turn off your computer. Call now.” That’s a classic tech-support scam—built to scare, not to help.

    ─────────────────────────────────────────

    What’s really happening

    • It’s only a web page (often opened by the call link) that abuses pop-ups, full-screen mode, and fake Windows/Defender art.
    • Microsoft/Apple/your ISP never lock your device through a browser or post a phone number to call.
    • If you call, they’ll try to remote in, install “fixers,” and charge you—or steal data.

    ─────────────────────────────────────────

    Do this immediately (quick exit)

    1. Do not call. Do not click.
    2. Kill the browser.
      • Windows: Ctrl+W (close tab). If stuck, Alt+F4 or open Task Manager (Ctrl+Shift+Esc) and End task on the browser.
      • Mac: +W (close tab). If stuck, Force Quit with ++Esc.
      • iPhone/iPad/Android: swipe up and force-close the browser app.
    3. Reopen safely (prevents the bad tab from restoring):
      • Windows/Mac: hold Shift while launching the browser to block session restore.
      • iPhone Safari: Settings ▸ Safari ▸ Clear History and Website Data.
      • Chrome mobile: Chrome ▸ ⋮ ▸ History ▸ Clear browsing data (Time range: All time).

    ─────────────────────────────────────────

    Clean up (2–5 minutes)

    • Run a scan. Windows: Windows Security ▸ Virus & threat protection ▸ Quick scan (then a Full scan later). Mac/mobile: update OS; run your trusted AV if installed.
    • Remove permission junk.
      • Browser Notifications/Permissions: Settings ▸ Privacy & security ▸ Site settings ▸ Notifications ▸ remove unknown sites.
      • Extensions/Add-ons: remove anything you don’t recognize.
    • Messenger/Facebook safety.
      • Tell your friend their account may be compromised.
      • Facebook ▸ Settings ▸ Password & security ▸ Where you’re logged in ▸ Log out of unknown sessions; Turn on two-factor.
    • If you entered info / installed software / called them:
      • Disconnect from the internet.
      • Uninstall any remote tools they had you add (AnyDesk, TeamViewer, Quick Assist sessions).
      • From a clean device, change passwords (email first).
      • Run Microsoft Defender Offline scan (Windows Security ▸ Scan options).
      • Contact your bank if you paid or shared card info.

    ─────────────────────────────────────────

    Prevent the next one

    • Treat surprise video calls as suspect. Decline and message the friend to confirm.
    • Lock calling down in Messenger: Settings ▸ Privacy ▸ Message delivery / Who can call you ▸ restrict to Friends.
    • Keep autosaving tabs off if you don’t need it.
    • Update OS and browsers; updates close the tricks these pages use.
    • Never let strangers remote into your device. Real companies don’t cold-call you for support.

    Final Reflection

    Scams run on panic. Breathe, quit the tab, then clean up. A browser page can’t “brick” your computer—but fear can make us hand over the keys.

    ─────────────────────────────────────────

    What I hear now

    • Close first, investigate second.
    • Call no numbers that pop up on a web page.
    • Verify with the friend; secure your accounts; turn on 2FA.
    • Slow is smooth, and smooth is fast.
