Possible Norton Update Problem?

When I went to get my email this morning, I couldn't get the email. A page came up that said {"res":{},"error":{"code":"3002","msg":"3002"}}  I called Verizon and they got me on the old email page until they figure out if it's their problem. However, a few weeks ago we had a problem with our Verizon internet due to a Norton update. We called Norton and they fixed the problem when they uninstalled  Norton 2010 on our two computers and installed Norton 2011.  Also last night we had Internet Explorer not responding message when we were trying to send or receive our Verizon email. That Internet Explorer not responding message is very similar to the one we had a few weeks ago, but it was related to getting on the Internet and if we did get on everything was freezing. Is anyone else having this problem?
