Just a warning. If you ever get a pop-up on your computer claiming to be from Microsoft (or any company) saying that you have a virus and need to call them or visit their website to get it removed, it is a scam. Microsoft does not do this.
Here is a link from the Federal Trade Commission about this: https://www.consumer.ftc.gov/article...-support-scams
Microsoft would like you to report these scams to them at: https://www.microsoft.com/en-US/reportascam//
