I've been using Sunbelt Kerio 4 paid version again this past week. My license has expired today, and it's $19.95 to renew for the year. The only thing that the paid version has over the free is, that it includes HIPS and Web Filtering. I don't use the Web Filtering. I'm thinking of just using it as a free firewall, but I do like the idea of the paid version having NIPS. The possibility of getting nag screens all the time to purchase a new license is not a pleasant thought. So what do the experts think. Should I go with a free firewall, Kerio4 or any other, without NIPS, or pay for the one year license and have a firewall with HIPS? If it matters any, I'm using AntiVir PE Premium antivirus.
