Question details

The user needs to safely dismiss a fake Windows technical support pop-up that claims the computer is blocked and urges them to call a phone number.

Product: Windows OS
Device & OS: Windows
Scenario: While browsing the internet or using the PC, a persistent and alarming pop-up takes over the screen, claiming the system is compromised and displaying a support number.
Observed behavior: A pop-up warning appears instructing the user to call a provided phone number to unblock their computer. This is a technical support scam, as genuine Microsoft warnings do not include phone numbers.

Before you start

Do not call the displayed phone number, click any links inside the pop-up, or provide any personal or financial information, as this is a malicious attempt to compromise your device.

Solution 1Recommended

Force Close the Browser and Restart Your Device

Use this solution to safely terminate the scam pop-up without accidentally clicking any malicious links embedded in the warning.

Tech support scam pop-ups are designed to lock your browser and create a sense of panic. Because clicking the standard 'X' or 'Close' buttons on the pop-up itself can sometimes trigger further malicious scripts, the safest method is to forcefully end the browser process.

Open Task Manager

Press the Ctrl + Shift + Esc keys simultaneously on your keyboard to open the Windows Task Manager.

End the Browser Task

In the 'Processes' tab, locate the web browser you are currently using (such as Google Chrome, Microsoft Edge, or Mozilla Firefox). Right-click on the browser's name and select 'End task'.

Restart Your Computer (If Necessary)

If the Task Manager does not open or your entire screen is frozen, press and hold the physical power button on your computer for about 10 seconds to force a shutdown. Wait a few seconds, then turn it back on.

Clear Browser Data

Once your computer restarts, open your browser. Do not click 'Restore pages' if prompted. Go to your browser settings and clear your recent browsing history and cache to prevent the pop-up from reappearing.

Official Microsoft Guidance: Always remember that real Microsoft error messages never include a phone number. For further protection, you can visit Microsoft's official guide on protecting yourself from tech support scams.

Frequently Asked Questions

What should I do if I already called the fake Windows support number?

If you called the number, do not grant remote access to your PC or provide payment details. If you have already given them access or paid them, immediately disconnect your computer from the internet, contact your bank to block any fraudulent charges, and run a full system scan using Windows Defender or a trusted antivirus.

How can I tell if a Microsoft security warning is real or a scam?

Genuine Microsoft error messages and system warnings never ask you to call a support phone number. Authentic alerts will only direct you to take action within the built-in Windows Security app or Windows Settings.

Can closing the browser normally trigger a virus from the pop-up?

Yes, clicking the 'X' or 'Close' buttons on the fake pop-up window can sometimes trigger malicious scripts that download unwanted files. It is always safer to use Task Manager (Ctrl + Shift + Esc) to force-close the entire browser application.
