For the past couple of weeks a red screen takes over my computer with this warning wanting me to call Microsoft Support at a number different from Microsoft's. Microsoft confirmed it was a scam and wanted me to buy a yearly subscription for them to come into my computer remotely and fix it, but I felt the price was ridiculous. I can close the screen by Ctl-Alt-Del, sign out and sign back in fine. But then a few days to a week later, it comes back, Anyone else have this happen? I just dont have a clue how to fix this.
