Need some computer guru assistance here. My wife just got a message on our home pc (Windows 10) that advised her to call 844-393-0481 to resolve some sort of error caused by spyware. This smells of a scam, but need to make sure. There is language in the error that states: "Please do not ignore this safely alert. If you close this page before calling us, your computer access will be disabled to prevent further damage to our network." Any suggestions?
