Auto Update has not worked for 2 weeks with no notifications!

I signed onto my computer tonight to see "Your computer is at risk" - virus & spyware definitions are not up to date and last update was 15 days ago. Immediately went to check settings and it shows auto updates and pulse enabled. Ran live update which said it was complete - still get the error message. 

It shows virus & spyware scan as complete and up to date

definitions update show last update 4/5

when I click on fix it tells me I have the latest version - I am going around in circles!

ALSO - when I tried to do a quick scan of the pc - left and came back to it after about 30 minutes - shows 0 files checked.

How can it be that the setting are right for auto updates and nothing is being done automatically?? I have never had this issue before.
