Is security alert telling to call 855 616 2892 valid

Question

My computer is giving me a security alert to call 855 616 2892.

Is this a real Microsoft number

Answer 1

Can you please hold down Ctrl+Alt+Del, then launch Task Manager, and then end all browser items there to close it. That page is definitely scam, but as long as you didn't call the number and engage in any of the requested activities, your computer is not hacked. It is just a pop up page that can have some audio effect (sometimes) and display in full screen mode, so it appears the computer is locked.

Scammers use various methods to trigger these pop-ups. Pop-ups are a form of online advertising. They are often integrated into websites or applications through ad services. Many websites use third-party advertising services to display ads. Sometimes, these ad services might inadvertently allow scam ads to be displayed. This does not mean the website itself is malicious, but it indicates a lack of stringent ad vetting.

Answer 2

I can't imagine that it is. If you call that number, you will soon be asked to give away all sorts of information you should give to strangers and you would lose money. Microsoft would not put up a security alert to have you call a number.

It looks like you have gotten some malware, and you should run a full scan with Windows Defender or whatever anti-maleware software you are running.
