I love Sygate Personal Firewall, but it doesn't work with Windows Vista. So I need a new one. I use Windows Defender for my anti spyware, which works great. I use NOD32 for my Anti Virus, which is simply amazing. But I am using the Windows Firewall and, well....it sucks. So, I don't care if it is free or not(although the less amount of money the better) but I need a good firewall that has a good amount of customizability so I can tweak it to do what I want.
