Hi street_lethal, regarding yr buggy ref to Privatefirewall, I had the identical issue.
Due to very helpful support from them we resolved it, the problem is the current version of Avast. I went so far as uninstalling quite a few progs and changes I made to my system (W7 Pro 64-bit) the past month but all to no avail, PF remained "buggy".
Eventually uninstalling most of my security progs and slowly rebuilding all it surfaced that Avast v6.0.1000 the cause. I've now reverted to Avast v5.1.864 and will make contact with Avast regarding this.
Avast is a super product, have been using it many many years, and I'll stay with it but I will not downgrade to any other firewall, PF doing an excellent job and very user friendly.
