- Product
- Windows
- Device & OS
- not provided
- Scenario
- Encountering a suspicious voice message or browser pop-up claiming the computer is locked.
- Observed behavior
- A fake warning message appears or plays, falsely stating the system is locked and urging the user to contact a fraudulent support number for remote access or payment.
Do not panic, and absolutely do not call the phone number provided in the message or pop-up. Remember that official Microsoft support will never proactively contact you with unsolicited warnings requesting remote access or payment.
Safely Close the Scam Warning and Scan for Malware
The most effective way to deal with a tech support scam pop-up or voice message is to force-close the browser and run a security scan.
These fake warnings are often designed to lock your browser in full-screen mode or generate endless pop-up loops, making it seem like your computer is genuinely locked. By forcing the application to close, you can bypass the scam interface entirely.
Do not click any links, buttons, or call the phone number displayed on your screen.
Press 'Ctrl + Shift + Esc' on your keyboard to open the Task Manager. Locate your web browser (e.g., Chrome, Edge, Firefox) in the list of active processes, right-click it, and select 'End task' to close the scam pop-up safely.
If your computer is completely unresponsive to keyboard shortcuts, press and hold the physical power button on your device for 5-10 seconds to force a shutdown, then turn it back on.
Open Windows Security or your trusted third-party antivirus software. Navigate to 'Virus & threat protection' and perform a 'Full scan' to ensure no malicious files were downloaded to your system.
Work Safely with WPS Office
While protecting your computer from online scams is crucial, having a secure and reliable office suite is just as important. WPS Office provides a lightweight, highly compatible, and free alternative to Microsoft Office, ensuring your documents remain safe and easily accessible.
Frequently Asked Questions
Will Microsoft ever call me to say my computer is locked?
No. Microsoft and other legitimate tech companies do not send unsolicited email messages or make unsolicited phone calls to request personal or financial information, or to claim your computer needs repair.
What should I do if I already called the scam number?
If you called the number and provided payment information, contact your bank or credit card company immediately to block the charges. If you allowed the scammers remote access to your PC, immediately disconnect your computer from the internet, run a full malware scan, and change your important passwords from a different, secure device.
How did this fake warning get on my computer?
These warnings are typically malicious advertisements (malvertising) or compromised websites that hijack your browser's display. They are designed to look like legitimate system alerts to panic you into calling their fraudulent call centers, even if your computer is actually free of viruses.
