Norton is rather a lot like scumware - it's basically impossible to remove.
Chances are, since multiple people are reporting problems, it prolly has something to do with something important getting busted by storms.
go to CMD type ping www.google.com -n 50 (that will give you an idea of how you're doing going west).
Then ping www.whitehouse.gov which should be east bound for you.
You could also do a tracert to a server you KNOW to be in chicago or New York - like the white house website and see if you're getting routed through Florida or some wackiness like that due to broken stuff.
Or maybe a hub you use has been overburdened recently.
