Unsolicited connection attempts by Symantec IPs, my last year

Constant connections from 143.127 and 166. whatever built into Norton software is not desired.

Like RussH in thread http://community.norton.com/en/forums/unsolicited-connection-attempts-symantec-ips?page=1#comments 

I am on my way out the door if "I" cannot control 'my' connections.

What is keeping this constantly connected and how do I shut it off? NIS 22.5.2.15
