Additional Microsoft Defender tools and services that provide security across various platforms and environments
This is a tech support scam, not a real Microsoft security alert. Genuine Microsoft error and warning messages never include a phone number, and Microsoft does not make unsolicited calls to tell people there is a problem with a device.
Do not call the number, do not click anything on the page, and do not give anyone remote access or personal or financial information.
To close it:
- Try closing the browser with Alt+F4.
- If that does not work, press Ctrl+Shift+Esc to open Task Manager.
- Find the web browser that is showing the alert, then select End task.
- If prompted when reopening the browser, do not restore the previous tabs/pages, or the scam page may reopen.
- If the browser cannot be closed, restart the computer.
If suspicious sites appear again in Microsoft Edge, report them from Settings and More > Help and Feedback > Report unsafe site.
The scam can also be reported at https://www.microsoft.com/reportascam.
