Keeps saying "at risk" though definitions updated

Keeps saying at risk, that virus & spyware definitions not up to date even through it's just been updated.  My date and time stamp on the PC is correct.  When I do the "fix", it updates if another update is there since I just did one, but even then it still doesn't say "fixed".  So it keeps saying "at risk".  As an aside, it's supposed to be on automatic update.  So I don't know why it's not doing it; just started happening other day.
