Dear Al Shane
Welcome to Microsoft Community.
I know you're having trouble with Comcast account security,and I understand your confusion!
Can you confirm whether the account you are experiencing is registered as a Microsoft account?
We are unable to confirm the status of your account, but in the case you have told us,it is possible that your account has been compromised by logging in to a dangerous website or by a virus on the device itself,so you can check if there is a problem with your account by clicking on the link:How to recover a hacked or compromised Microsoft account - Microsoft Support
We look forwared to hearing back from you.
