How to Recognize and Avoid Tech Support Scams

Security / Antivirus scam tech support fraud pop-up fake virus social engineering By Kerry · Updated 03/04/26 10:56 PM
Tech support scams are one of the most common fraud schemes targeting small businesses. They can look and sound very convincing. Here's how to recognize and handle them. What tech support scams look like: Pop-up on your computer: A full-screen pop-up (sometimes with an alarm sound) appears saying your computer is infected, your files are being stolen, or your Microsoft/Apple account is compromised. It shows a phone number to call "immediately." Phone calls: Someone calls claiming to be from Microsoft, Windows support, your ISP, or even us. They say they've detected a virus or hack on your computer and need remote access to fix it. Emails: An email appears to be from Microsoft or another tech company saying your account has been compromised or your subscription is expiring. The truth: Microsoft, Apple, and legitimate IT companies do NOT proactively call you about viruses on your computer. They do not send pop-ups with phone numbers. If you get an unsolicited contact about your computer's security, it is a scam. What they're after: - Remote access to your computer (to steal data, install malware, or lock files for ransom) - Your credit card number (to "charge for the repair") - Your Microsoft or bank account login What to do if you see a pop-up scam: 1. Do NOT call the number shown 2. Do NOT click anything in the pop-up 3. Press Alt + F4 to close the browser window, OR 4. Press Ctrl + Shift + Esc > Task Manager > find the browser > End Task 5. If you can't close it, hold the power button for 10 seconds to force the computer off 6. Run a full antivirus scan after restarting What to do if you already called the number or gave them access: 1. Disconnect from the internet immediately (unplug Ethernet or disable Wi-Fi) 2. Call us at (269) 261-0269 right away — this is urgent 3. Change your Microsoft 365 password and any other accounts you accessed during the call 4. Do not use the computer until we've checked it What to do if you gave them a credit card: Contact your bank or card issuer immediately to dispute the charge and watch for further unauthorized activity.
