I've been using Comodo Firewall for a while no and have been happy with it until about month or two ago. Every time I launched Firefox my processor started going crazy, FF lagged ("Not Responding") for about a minute and then was fine. Thought it was FF at first so I completely uninstalled and reinstalled with no add-ons to no avail. Then I decided to watch task manager while launching FF and was surprised to find CFP.exe jumping to over 56% of CPU and 3-4k memory -- and I'm running a Core 2 Duo T7500 at 2.2Ghz. Before launching and while FF is running, cfp.exe is at 0% and the same about 3-4k of memory. I ran "Diagnostics" from the miscellaneous tab of Comodo, but it says everything is OK.
I've noticed the same problem when launching Pidgin, my Cisco VPN client, or basically anything else that tries to connect to the internet for the first time as launching -- it all just freezes upon launch. I vaguely remember installing a FF update right before this started, but have done new updates since then and all of my other programs are up to date. So the FF update shouldn't have an effect on Pidgin or the VPN client.
Any ideas on whats wrong or how to solve this? The only thing I can think of, and haven't done yet, is to fully uninstall, clear all files, and then reinstall Comodo.
