Hi, I am an Independent Advisor.
Let me help you with this issue.
I understand you got a pop-up on your screen with a Microsoft technical support number.
The number that showed up on your screen is not an official Microsoft support number. It’s part of a tech support scam. Microsoft does not display phone numbers for you to call on pop-up messages.
Scammers often use pop-up warnings to trick people into thinking their computer has a virus or other issue, prompting them to call a fake support number. Once contacted, scammers may guide victims through steps to gain remote access or install harmful software.
Please do not call the number, to close the popup, just hit[ ALT+F4] or [CTRL+ALT+ESC] then open Task Manager, and close all open browsers.
