    Installed 8.7, reverted to 8.5 now won't start

      We installed 8.7 through EPO 4 and had lots of problems with speed.

      We decided to go back to 8.5 so issued a remove command for 8.7 and install command for 8.5.

      Now the McAfee realtime service will not start, it issues an error in the event log:

      Could not contact Filter Driver.
      Error = 0x1 : Incorrect function.

      Any ideas?
