I just had to rebuild my system. I installed Windows XP, then downloaded all the Windows updates, include SP2.
After that I installed Norton Systemworks with AV.
Since then, MS Security Center remains red and refuses to grips with it. It says that it recognizes that Norton AV is installed, but says that its status is unknown. It provides no way to resolve this, and simply stays red, which is simply wrong.
Isn't there some way to get Windows Security to determine Norton's status and be happy (go green)?
