Browser Warning Says to Call Support? Close It Without Calling

A page fills your screen, a voice repeats a warning, and a message says your computer is locked until you call support. Do not call the number on that page. A familiar logo and an alarming sound do not establish who is speaking.

This guide is for Windows users facing that warning in a web browser. The task is specific: close the browser session and reopen without restoring the warning page. You do not need to settle the computer's overall condition before ending the page's demands.

A phone number is a reason to stop

The FTC's tech support scam guidance explains that fake warnings can imitate familiar companies and direct you to a supposed technician. Real security warnings do not ask you to call a phone number. The call can lead to requests for remote access or payment.

Here is an invented example:

Windows security alert. Do not close this window. Call the support number below to unlock your computer.

The instruction to keep the window open is part of the message. It is not an instruction from someone you have independently chosen to help you. Do not type a password, download a repair tool, or let a person reached through that number connect to your computer.

Close the browser using Windows controls

A page can imitate a close button. Use the browser's own controls or Windows, rather than buttons drawn inside the warning.

Microsoft's guide to Windows system tools documents the Task Manager shortcut and its use for ending unresponsive programs.

1. Try closing the browser window normally. Use its window close control, not a button in the webpage. If the page hides the browser controls, keeps returning, or stops you closing the window, move to the next step.
2. Press Ctrl + Shift + Esc together to open Task Manager. This is a Windows tool outside the webpage. Ending the browser can discard unsaved work in other open tabs, so use it when normal closing does not work.
3. Find the browser in Task Manager's process list. Select the browser you were using, such as Microsoft Edge, Google Chrome, or Firefox, and choose End task. Depending on your Windows version, you may need to expand Task Manager to see the list. Do not end unfamiliar system processes.
4. Open the browser from your usual Start menu or taskbar shortcut. If it offers to restore the previous session or pages, decline that offer. Restoring them can bring the warning back.

Microsoft's guidance on tech support scams describes pages that use full-screen displays, repeated popups, and audio to make a warning look like it comes from Windows. Closing the browser ends your interaction with that page; reopening it without restoring the session keeps you from deliberately loading the same page again.

Check the result, not the warning's promises

The observable result is a newly opened browser without the warning page. You have ended that session without calling its number. That is all this check establishes: it is not a scan or a clean bill of health for the computer.

If the warning returns even without restoring the session, stop interacting with it. Use a support route you already know, such as the computer maker's official support site reached independently, and describe when the warning appears. Avoid a support number supplied by the warning or an advertisement promising an immediate repair.

If you already installed software, allowed remote access, shared a password, or paid, closing the page is not enough. The FTC guidance above has steps for those situations. Our guide to what to do after a scam can also help you organize a response. Tell your independently chosen helper what you actually did, rather than relying on what the warning claimed had happened.

Keep the next decision separate
