Vulnerability protection definitions are not up to date

Norton 360 started breaking Time Machine backup, which is insane itself considering there is still no fix for this!!! Basically, I've lost the backup I had for years, which means I lost some data, which means this thing lead to data loss!

Tried to disable some protection and re-start the backup, which failed anyway. But now even Norton itself can't get back to normal work! I am trying to restore protection and getting this:

(Lol, I can't drag and drop files here, nice too! See attachments, I uploaded them in the order I am seeing them.)

I have just one question – how do you sell this piece of "bug"? Can I trust this protection? I do have doubts already. I sav people are using it for years, how's that? I paid for this, got lots of problems and no solution still!
