- Device & OS
- not provided
- Scenario
- Encountering a fake technical support scam pop-up while browsing the internet.
- Observed behavior
- A malicious webpage freezes or displays persistent alerts claiming a virus infection, urging the user to contact a fake tech support phone number.
Do not panic or interact with the pop-up. Legitimate technology companies like Microsoft will never lock your computer or ask you to call an unsolicited support number.
Safely Close the Scam Pop-Up
Forcefully close the browser to prevent the scam from progressing and stop the intrusive alerts.
Tech support scams often use aggressive scripts to lock your web browser, making it difficult to close the tab normally. You must use system shortcuts to safely bypass the pop-up.
Do not click anywhere inside the pop-up window, including any 'Cancel' or 'X' buttons within the webpage itself, as this may trigger further malicious actions.
Press 'Alt + F4' on Windows or 'Command + W' on Mac to safely close the active browser window.
If the browser remains locked, open the Task Manager (Ctrl + Shift + Esc on Windows) or the Force Quit Applications menu (Option + Command + Esc on Mac), select your browser, and click 'End Task' or 'Force Quit'.

Run a Full System Security Scan
Ensure your computer is entirely free of malware or potentially unwanted programs that may have triggered the redirect.
Secure Compromised Accounts
Take immediate action to protect your identity and finances if you accidentally interacted with the scammers.

Frequently Asked Questions
Can a website actually scan my computer for viruses?
No, a standard website cannot independently scan your hard drive for viruses or completely lock your operating system. These pop-ups use aggressive browser scripts to display fake full-screen images, creating the illusion of a locked device.
What should I do if I already called the number on the pop-up?
If you called but did not provide personal information or grant remote access, simply hang up. If you allowed remote access, disconnect your computer from the internet immediately and seek professional technical support to clean your system.
Does Microsoft ever send unsolicited tech support warnings?
No. Microsoft and other legitimate tech companies will never proactively display pop-up warnings containing phone numbers, nor will they ask you to pay for technical support using gift cards or cryptocurrency.
How can I prevent fake tech support pop-ups in the future?
To prevent these scams, keep your web browser and operating system updated, use a reputable ad-blocker, and avoid clicking on suspicious links or downloading software from unverified third-party websites.
