Your screen freezes. A loud alarm sounds. A pop-up reads: "VIRUS DETECTED — Call Microsoft Support Immediately: 1-800-XXX-XXXX." This is a tech support scam, and it cost Americans $924 million in 2024 (FBI IC3).

How It Works

  1. A pop-up, browser redirect, or phone call triggers alarm about a "virus" or "security breach."
  2. The victim calls the provided number and reaches a convincing "technician."
  3. The technician requests remote access to the computer to "fix" the problem.
  4. Once connected, they demonstrate fake "evidence" of infection (normal system files, logs).
  5. They request payment for "support services" — ranging from hundreds to thousands of dollars.
  6. Some then steal banking credentials, install actual malware, or request gift cards for payment.

Key Facts That Expose This Scam

  • Microsoft, Apple, Google, and antivirus companies never call you unsolicited.
  • Legitimate companies don't use pop-ups with alarm sounds to alert you to viruses.
  • Real tech support never requests gift cards, wire transfers, or cryptocurrency as payment.
  • Real tech support never needs to access your banking or financial accounts to fix a computer problem.

If You See a Tech Support Pop-Up

  1. Do NOT call the number on the screen.
  2. Close the browser tab or window. If the browser is frozen, force-quit it.
  3. Run a legitimate antivirus scan (from software you already have installed).
  4. If you've already called and given remote access: disconnect from the internet, change all passwords, and call your real bank immediately.
