I'm talking about the Firewalls, of course. Also, why you think PC Tools Firewall Plus is the worst? It passes ShieldsUP testing and is a leader in Matousec's tests. PC Tools Firewall Plus is a freeware Windows personal Firewall. It's very lightweight and unobtrusive, as it is built using the new Windows Filtering Platform (WFP) - therefore offering great and precise support to newest versions of protocols (IPv6) and Windows OSes, both 32-bit (x86) and 64-bit (x64) versions of: Vista, Server 2008, 7 and Server 2008 R2. They still support XP as well, but only the 32-bit (x86) version.
