Sunbelt Personal Firewall used to be called the Kerio Personal Firewall (KPF). Kerio was going to discontinue it, but Sunbelt acquired it from Kerio to save the product from "going under". We needed a new name, and changed 'KPF' into the new 'SPF' ! (so much for software geeks being creative...) And here is a special, limited time offer. This US$9.95 offer is only valid for a short while, you have to BUY IT NOW to be able to benefit! (Tell your friends right away)
