First, it’s a scam. Microsoft doesn’t make calls like this.
If you call them, they charge by the minute to help you, but it is a call that you initiate.
Secondly, don’t trust your computer to someone you don’t know.
These people want to gain access to your computer to plant viruses.
The viruses may lay dormant for a time but they will eventually lock your computer fully.
Then you will receive another call or they may have given you a call back number in case you have problems, and at this time they will instruct you that in order for you to get your computer cleaned up you need to get a prepaid card for up to $300 to give them to fix the issue.
