Yes I have Verizon FIOS.
It seems lately that whenever there is a Norton update, chaos! I don't have alot of time to figure this out, so I normally wait a few days and it appears to fix itself. I lost access to everything on Norton (can't go into settings etc) and also access to IE. But I could always use Google. Now I can't access that unless I disable the firewall.
I'm running constant updates, they appear to download and install, and I get that happy green check mark. However, the Norton window never shows that the updates were recently updated - it still says '2 days ago', even though it was this morning.
