I think I got the defender pop up scam and gave the person remote access to help me run diagnostics because I believed they were from Microsoft.

Hi, I am Dave, I will help you with this.

1
If you logged into accounts while they had access to your PC, you should immediately change the passwords on all your accounts to a new long and strong password, and on your Microsoft account enable two step verification.

2
If they had access to your PC, that indicates you installed a utility like TeamViewer or some other remoting utility, you need to uninstall that completely from your PC.

The option is to open the Settings App, then go to Apps - Installed Apps.

Set the sorting by Date Installed On and uninstall any strange app that may be a remoting app you do not recognise that was installed on the date they had access to your PC.

3
Then run a full scan with the Microsoft Safety Scanner:

Then, run a full scan with the free version of Malwarebytes.

Do either of those report malware on your PC?

Thank you DaveM121.

I sent this message from my phone but I will want to follow your instructions at home later on my PC.

I stopped and spoke to a geeksquad rep and they suggested both steps 1 and 3. Thank you for the extra suggestion. I will follow up with an answer when I'm finished looking for the remote utility and running Malwarwbytes. It's alot. But thank you for the help. I feel much better.

Glad to help!
