Have been trying to understand the difference between Norton for small business and Norton 360 Premier 5.0- I am currently using for 1-3 PC's. My subscription expires in 3 days. Issues: forced to disable Smart Firewall permanently (for now) as it constantly interfere with home network on Win 7 Home Pre. 64 bit. s not possible to compare Norton home products to Norton small business products sidexside. I run a small business from my home using a Sony PC aio, a Dell laptop, an HP AIO photosmart Printer which has also been problematic w/network issues I upgraded to Win 7 Home Pre 64.bit (from Vista 2+ years ago). Apparently the only difference between Internet Security 2012 and 360 is the larger mg off site backup size. I posted this privately -thought no one else wd. care about my very specific problem but was advised to post here as more appropriate, sorry other users.
