360 blocks dns access

I have a new All-in-one AIO 700 24ISH.  Last week I lost access to the internet and local network.  I ran the Norton help and it loaded the Norton DNS server address in my IP4 configurations.  This let me access the internet but my local services still didn't work.  I contacted Norton and they spent about 3 hours researching the problem.  Finally the tech said he needed to pass this problem up the food chain.  At that point I got disconnected.  I removed Norton 360 and all is well.  I also tried McAfee and it didn't cause any problems.  I would switch but have a subscription to Norton for the other computers in the house(oh they are working fine).  I also don't like the idea of using Norton Safe servers for my internet access and would rather just use my default ISP DNS.  Any ideas?
