Have you gone to Windows update? Are you fully up to date? If so then you have SP2 installed. It should show up but only if you check the box in the Add/Remove programs to show updates if oyu have SP2 isntalled or not.
I would get rid of McAffee and get either AVG or Avast. Defender is just a Anti-Spyware so i would think that it is your expired McAffee that is causing this issue.
