I have the same problem.
In my taskbar and in the program, i can see that the virus database is 12383 from 20151009.
But my eset nod32 icon has a red triangle, and in panel i can see the red message :"The virus data base is old, it must be update".
And when i try to update the virus data, it says that i have the latest version...
PS : Sorry for grammar mistakes, i'm french.
