SCAM EMAIL THAT SOMETHING IS WRONG WITH YOUR COMPUTER

The email shows "Microsoft account team" as the source and the subject line is "Microsoft account unusual signin activity." The text of the body continues with "We detected something unusual ..."

These emails should NEVER be opened. It is a scam and it is "phishing" for your financial information or some kind of payment. The real Microsoft never contacts you this way and is certainly not monitoring your sign-in activity anyway.
