    "Your Computer Has a Virus!" Pop-up

    Scary pop-up. Loud sirens. Phone number. It's all fake.

    Don't call the number.

    No matter what the pop-up says, do not call. The number is NOT Microsoft, NOT Apple, NOT McAfee. It goes to a scam call center where they'll convince you to install remote-control software, then drain your bank account.

    Microsoft and Apple never show pop-ups telling you to call them.

    First — close it

    If the pop-up locks the browser:

    • Mac: Press +Option+Esc → pick the browser → "Force Quit".
    • Windows: Press Ctrl+Shift+Esc → highlight the browser → click "End Task".
    • Last resort: Hold the power button to turn the computer off. Wait 10 seconds. Turn back on.

    When the browser opens again, it might offer to "restore tabs" — say NO. That re-opens the bad page.

    Second — clean up the browser

    Chrome / Edge:

    1. Click the three dots (top right) → Settings.
    2. Privacy and security → Clear browsing data.
    3. Time range: "All time". Tick everything. Click "Clear".

    Safari:

    1. Safari → Clear History → "All History".
    2. Safari → Settings → Extensions — remove anything you don't recognize.

    Third — run a free virus scan

    In most cases, this kind of pop-up is just a scary website — your computer doesn't have an actual virus. But run a scan to be sure.

    Mac:

    • Macs have built-in protection. Often nothing more is needed.
    • For a deep scan, install Malwarebytes for Mac (free) — well-trusted.

    Windows:

    • Click Start → type "Windows Security" → open it.
    • "Virus & threat protection" → "Quick scan".
    • Or for a deeper scan, install Malwarebytes (free).

    If you DID call the number

    1. If you let them remote-control your computer: Disconnect from the internet (unplug Ethernet, turn off Wi-Fi).
    2. Restart the computer. The remote-control software is usually a stand-alone program — uninstall anything they had you install.
    3. Change your important passwords from a DIFFERENT device — bank, email, Apple ID, Google.
    4. Call your bank. If they had you "verify" anything, treat it as if your account was breached.
    5. If they charged your credit card — call the card company; reverse the charge.
    6. Take the computer to a real local repair shop for a full clean (around $100-$150).

    Prevent next time

    • Use a free pop-up/ad blocker like uBlock Origin (Chrome, Firefox, Edge).
    • Don't click on tempting links in random emails — most of these pop-ups come from sketchy sites.
    • Real Apple, Microsoft, and your antivirus will not pop up a giant warning. They quietly notify in the system tray.
