Fake virus warnings are designed to create panic. They may fill the screen, play an alarm, show a countdown, use Microsoft or Apple branding, claim your computer is locked, or warn that your bank information is being stolen. The goal is usually to make you call a scammer or install remote-access software.
Do not call the number in the warning
The Federal Trade Commission says legitimate tech companies do not put phone numbers in pop-up security warnings. Do not click the message, pay a fee, buy gift cards, send cryptocurrency, or allow remote access.
Signs the warning is probably fake
- It tells you to call a phone number immediately.
- It claims Microsoft, Apple, your internet provider, or a security company detected a problem through a random webpage.
- It uses alarms, flashing colors, a countdown, or threats that your files will be deleted.
- It says closing the window will damage the computer.
- It asks you to install AnyDesk, TeamViewer, UltraViewer, Quick Assist, or another remote-control tool.
- It demands payment by gift card, wire transfer, cryptocurrency, or a “refund” transaction.
- It asks for banking passwords, Social Security numbers, or unrelated personal information.
What to do right now
- Do not interact with the warning. Do not click its buttons, links, or phone number.
- Close the browser. Try Alt+F4 on Windows or Command+Q on a Mac. If the browser will not close, use the operating system's task manager or restart the computer.
- Do not restore the suspicious tab. When the browser reopens, decline any option to restore the previous session if it would reopen the warning.
- Run updates and a trusted security scan. Use the built-in Windows Security tools or another security product you intentionally installed.
- Call someone you trust using a number you already know. Do not use contact information displayed by the pop-up.
If you called but did not give access
Hang up. Block the number if practical. Do not answer return calls. If you gave only your name or phone number, be alert for follow-up calls and messages that reference the incident to sound convincing.
If you allowed remote access
Disconnect the computer from the internet and stop using it for banking, email, shopping, or password changes until it has been checked. From a different trusted device, change important passwords—starting with email and financial accounts—and enable two-factor authentication. Contact your bank or card issuer if payment information was exposed.
Remote-access software may still be installed after the call ends. Simply closing the visible window may not remove it.
If you paid the scammer
Contact the bank, card company, wire service, gift-card issuer, or cryptocurrency exchange immediately and ask whether the transaction can be stopped or flagged. Report the incident to the FTC at ReportFraud.ftc.gov. If identity information was exposed, use IdentityTheft.gov for a recovery plan.
Could a real infection still cause pop-ups?
Yes. A malicious browser extension, notification permission, adware, or malware can create repeated pop-ups. The warning itself is not proof that the dramatic claims are true. A proper check looks at browser settings, installed programs, startup items, security logs, extensions, notification permissions, and scans from trusted tools.
