Windows 10: unusual logins to my microsoft account

I have noticed recently successful logins on my microsoft account using my alias but which have been successful without using the authenticator app i have set up and also using Internet Explorer a browser i never use and which i have done my best to disable. I have had contact with microsoft help but we seem to be going round in circles as no one seems to know why this is happening. I have scanned my pc with Norton, Norton Power eraser and Malwarebytes and it comes up clean other than a query about some native image files which Norton says are ok. I am using two step authentication on all my email and other accounts and I am now removing trusted status to devices everytime i log out of microsoft. Despite this successful logins are popping up from Internet Explorer. Does anyone have any idea what might be happening.

Microsoft account unusual sign-in activity

Since you have checked your recent activity and confirmed that there were no unusual activities made, please provide us the following information:

• Do you have a new phone from a different provider, or any new apps were installed that might try to sign in using your account?

• Some apps that sign in on your behalf including email apps and social media apps tied to a Microsoft account.
• Apps that sign in on your behalf will need to ask for permissions to do so when they are installed, and will prompt you for your Microsoft account and password.

• Do you remember having to enter your password when you set up any Windows Phone or Windows apps?

If you can't think of any reason why a sign in would occur
from a different location, we strongly suggest that you reset your password and check for unusual activity on any other accounts that you might have.

If you suspect that your account was compromised, you can do the following:

• If apps, services, or subscriptions were purchased with this account:

• Sign-in to account.microsoft.com
• Click Review your purchases and make sure there were no new transactions that you didn't make or expect.
• Click Billing info and make sure your billing info wasn't changed.

• If you're using OneDrive to store and share files, photos, or other data:

• Sign-in to OneDrive.live.com
• Click Shared on the side menu
• Review the folders and files that are being shared to make sure files are not being shared with people you don't know or that any shares you made weren't deleted.

• If you're using an Outlook or Hotmail email account:

• Sign-in to outlook.com
• Click the gear-shaped Settings icon, then click Options.
• Check the following settings and restore any that might have been lost or changed:
• Check the deleted mail folder and Contacts lists to make sure unusual messages or contacts weren't added, sent, or deleted.

Please post back with the result for further assistance.
