That's a fake so-called Tech Support scam alert/warning which you are seeing in your browser.
"Remember that real error messages from Microsoft, or other big tech companies, never include phone numbers for you to call them.
If your screen suddenly fills with scary pop-ups you should immediately close your browser (try pressing ALT+F4 if you can't do it with your mouse). If you can’t close your browser try restarting your computer."
