I just setup a W8.1 system and when I tried to setup Defender I am told in the action center that defender real time protection is not running. When I select the big red button that says TURN ON, the system tries and comes back with "real time protection is turned off, you should turn it on". I checked TURN ON NOW, but it didn't come on. I want to use Defender as my anti-virus but I'm not sure it's on.
