The fake tech-support pop-up

A fake warning pops up on your screen claiming your device has a problem and urging you to call a number or click a link—but it's not real.

Documented by the FTC & FBI IC3 · reviewed 2026-07-06

How it works

While you're browsing or using your device, a colorful alert suddenly appears saying your computer or phone is infected, locked, or in danger. The pop-up uses urgent language and official-looking logos to create panic, then pressures you to call a phone number or click a button right away. If you call, someone posing as tech support will try to gain remote access to your device or convince you to pay for fake repairs.

Red flags

• A pop-up warning about a virus or security problem appears without you requesting a scan
• The message uses scary language or urgent tone and pushes you to act immediately
• A phone number, chat link, or download button is prominently displayed in the pop-up
• The logo or branding looks similar to a real company but something feels slightly off

What to do

• Close the pop-up by clicking the X or pressing Escape—do not click any buttons or links inside it
• Restart your device in Safe Mode or use your legitimate antivirus software to scan if you're genuinely concerned
• Report the scam at reportfraud.ftc.gov so authorities can track and stop it
