I have two computers. One I have Zone Alarm free and my older computer had Norton 2002,which I just removed. The subscription was about to run out. I am trying LnS on the older computer to see how I like it. I may put it on both if all works out. I have some questions. No1. Is LnS better than ZA and how is it better. No2. Is it necessary to load the Internet Filtering Rule Set? I have tried loading it but it said it couldn't open it. I am trying to use Blackspears instructions. Being a NOD32 user I am familiar with his help.
