Windows 10: Virus & threat protection - Setup OneDrive... can only choose "Work or School"

Whenever I open "Windows Defender Security Center" it shows me a warning/reminder under "Virus & threat protection" to "Set up OneDrive". However, OneDrive seems to already be running and syncing. But, what's even more confusing is; When I try to run the setup and enter my email-address, the option for "Personal" is greyed-out. I can only choose "Work or school". Just above the buttons it says: "This email address is used for both OneDrive and OneDrive for Business. Which would you like to sign in to first?" This is very odd, because I don't remember ever creating any OneDrive for Business account.


So, my assumption is: the "Personal" option is greyed-out because it's already running. My question is: How on earth did I get a OneDrive for Business account associated to my email address without ever setting it up? AND, how do I get rid of this annoying warning/reminder. (My OCD teaches me, I have to have all green checkboxes )



PS: Also, why is the OneDrive "Category" for posting Locked?!

Virus and Threat protection not working.

It keeps saying to restart virus and threat protection. When I click on restart, it does restarts, but stops again after a few seconds. I have tried almost everything but nothing worked.
