Spotting the Red Flags: Protecting Missouri Seniors and Small Businesses from Tech Scams

A comprehensive survival guide for recognizing fake pop-up warnings, Microsoft impostor phone calls, and phishing threats targeting residents in Saline, Pettis, and Henry counties.

Every week in Saline, Pettis, and Henry counties, dozens of residents and small business owners encounter alarming full-screen warnings claiming their computer is “infected with a Trojan” and ordering them to immediately call a toll-free 1-800 number.

These warnings often emit loud robotic sirens, lock the mouse cursor, and display official-looking Microsoft or Apple logos.

It is 100% fake.

Anatomy of the Fake Tech Support Scam

Here is how the scam works:

  1. The Trap: While browsing a news site, recipe blog, or clicking an errant link in an email, a malicious web script launches a full-screen browser window that prevents you from easily clicking the “X” button.
  2. The Panic: The screen claims “YOUR COMPUTER HAS BEEN BLOCKED. CALL MICROSOFT SUPPORT AT 1-888-XXX-XXXX TO UNLOCK.”
  3. The Extortion: If you call the number, an overseas call-center agent answers pretending to be a senior security engineer. They ask you to install remote software (like AnyDesk or TeamViewer).
  4. The Theft: Once inside, they open confusing diagnostic screens, claim your network is hacked by international criminals, and demand $300 to $1,500 via credit card, wire transfer, or gift cards to “clean” the machine.

What Real Tech Companies NEVER Do

Remember these golden rules:

  • Microsoft, Apple, and Google NEVER display phone numbers on error screens asking you to call them.
  • No legitimate tech company will ever ask you to pay with gift cards (Target, Apple, Walmart).
  • Antivirus programs will never lock your screen completely and demand an immediate phone call.

What To Do If You Encounter a Scam Screen

If a scam screen pops up on your monitor:

  1. DO NOT CALL THE NUMBER ON THE SCREEN.
  2. DO NOT ENTER YOUR CREDIT CARD OR SOCIAL SECURITY NUMBER.
  3. Force close your browser: Press Ctrl + Shift + Esc on Windows to open Task Manager, right-click your browser (Chrome, Edge, Firefox), and select End Task.
  4. If the screen is completely frozen, hold down your computer’s power button for 10 seconds until it powers off completely, then turn it back on.
  5. If you already allowed someone remote access to your computer, immediately unplug your router / disconnect from the internet, power off the machine, and call a local professional.
