Hi my name is ***** ***** I will be the expert working with you today to help and resolve the problem you have posted.
I am sorry to hear that you are having such trouble. I will try my best to help you answer your question.
Microsoft or any computer company never calls any customer and if you want to verify you can open google and check for Microsoft toll free number or the number you got on the pop screen. The email or the popup message you got may have a different number where you can call and they will lure you and make you understand the your computer is at risk and they can extort $300 to $500 from you and will disappear.
if it in your email mark them as spam and block.
check out the link i attached.
