I have a similar problem with KIS 2013. Win 8 Pro - Action Centre is telling me that the Firewall, AV & anti-spyware software is all turned off. I go into AC and select the button to select the software and although it obviously sees KIS as being installed selecting the option to turn it on has no effect. All the checkboxes are checked in the AC setting.
I also have the WHS (2011) connector telling me these are turned off.
KIS is telling me all the main components are enabled (Safe money is turned off).
This only started in the past week.
Thanks, Simon
