If you’ve ever seen a pop-up warning that your computer is “infected” and urging you to call Microsoft, you’ve likely encountered one of the most common online tricks: Microsoft tech support scams . These scams are designed to scare users into handing over money or giving hackers access to their computers.
Understanding how these scams work and knowing what to do if you see one can protect your personal information and your wallet.
What Are Microsoft Tech Support Scams?
Microsoft tech support scams are fake messages that appear on your screen. They may:
- Pretend your computer is infected with a virus
- Claim your Microsoft license has expired
- Provide a phone number to call for “help”
These scams often lock your screen with urgent warnings, but they are not from Microsoft.
Signs You’re Dealing With a Scam
- The message appears suddenly while browsing the internet
- A phone number is displayed, asking you to call immediately
- You hear loud warning sounds or see flashing alerts
- The message prevents you from closing your browser normally
Important: Microsoft will never display a phone number in a pop-up asking you to call for support.
What To Do If You See a Fake Alert
- Do not call the number. It connects you directly to scammers.
- Close your browser. Use Task Manager (Ctrl + Shift + Esc) if needed.
- Run a system scan. Check for malware or suspicious programs.
- Call a professional. If you’re unsure, contact Houston Tech Guys to helps your computer is safe.
Verify independently and respond to exposure
Treat phone numbers, sender names and amounts described here as details reported in the source case, not proof of who owns a number or who placed a call. Caller ID and email sender displays can be spoofed. Open the organization’s official app or type its known website yourself; use contact information obtained there, not from the message. Do not share passwords, recovery codes or unexpected sign-in approvals. If you shared access or credentials, disconnect an exposed device, use a different trusted device to change passwords and review sessions, and contact the affected bank or service promptly. Keep evidence and report the message. A suspicious message alone does not prove a device or account was compromised.
