Norton is causing 1TB Western Digital My Book World Edition to Freeze

Hello Norton community,

 

I have Norton IS 2010 on my desktop, I am running Windows 7-64bit.  I have noticed something strange lately.  When I go to my network security map to add trust levels to devices on my network, my NAS (stated in the subject line) will stop responding to any requests for anything.  I cannot access it, or even ping it.  To fix the issue I have to unplug the power out of my NAS and plug it back in.  Once the NAS reboots, I can ping and access it.  I have tested out this issue, and it is everytime I open the network security map.  I no longer have any need to go in there as I have configured all of my devices, but if you could possible look into this so that I do not run into this issue later, it would be greatly appreciated.
