Windows Action Centre

I have 2 hard-drives (C being an SSD, D being the larger HDD) with most stuff installed on my D drive (including NIS). Turned my cpu on this morning and it didnt want to recognise my D drive for some reason, so all the stuff installed on it wouldn't load. No problem - rebooted the computer and all is good. only issue is now Windows Action Centre is telling me i have no firewall, anti-spyware and anti-virus software turned on/installed.

 

I've tried following the steps listed in links like this -> http://community.norton.com/t5/Norton-360/Windows-7-Action-Center/m-p/174416

but no luck. However, my problem seems somewhat different to those in that -

a) those threads seem to be mostly for norton 360 and

b) in those threads most are saying that WAC is telling them that norton is switched off. for me WAC is not even mentioning norton; just that the windows-based anti-virus programs are not turned on.

 

i realise that NIS is running and is secure, but this is still an annoying problem. Any fixes or should i just ignore it and let it be?

 

Thanks
