Unable to OPEN or UPDATE Defender

I am in the same boat, ie, unable to update and Defender keeps closing, when I close the computer. It does NOT run every day as I requested either.

To run a scan took a few hours but 5 & 12 seems excessive, probably the programmes you have running.

I'd love to be able to keep Defender running all the time and be able to update. Perhaps a Microsoft can tell us why we can't do these things!
