They claimed to be from Microsoft saying that they got an alert that your computer has an error. Microsoft has a free scan you can use on their own website (microsoft. Com) if you’re really worried use that but I searched and Microsoft doesn’t call you about problems on your computer.
Just received call from the above number, No idea who they are but I refused to answer. Received 7 calls at intervals within 3 hours from another strange number +119175623846.
