I can't be really sure whether what I'm saying is correct or not, but
personally I'm inclined to think that perhaps Windows did not recognize
Norton, or your version of Norton anyway. However, this is pretty weird
because I believe that Microsoft made it so that Windows could recognize most
"mainstream" protection softwares, and Norton is pretty well known.
As for Windows Defender, have you tried turning it off and on again? Unlike
firewalls, turning an anti-spyware program off for a jiffy wouldn't
jeopardize your computer's safety. But if you don't want to take the chance,
you could get anther anti-spyware program, and then play around with Windows
Defender while the other program is doing it's job.
As for your Network and Sharing Center problem, I did a google search and
this is what I found: http://forums.techarena.in/showthread.php?p=3104870
