Hi, I used to use sygate personal firewall pro but since they aren't supporting it, I decided to try outpost. It was fine for a month or so, but yesterday I installed netbeans, and when ever I tried to lauch netbeans I got the BSOD. I tried this 3 times or so to make sure it wasn't an unrelated error, but when the problems kept occuring I decided to uninstall outpost and see if I could then launch netbeans. The result was with outpost uninstalled netbeans could be launched successfully. I decided it was time to switch firewalls since I need to use netbeans, so I installed the kerio trial. First thing I did after the reboot was run netbeans, which was fine. Later connected to the internet and opened up some firefox windows and I got the damn BSOD again. This time the error was slightly different. I got the same error as this guy. http://www.wilderssecurity.com/showthread.php?t=122752 I don't know the version numbers, but I was using the most recent non-beta version of outpost and kerio. I really liked outpost, but I require netbeans also. Has anyone had this problem, or know how it can be solved. Agnitum didn't have anything useful to tell me except there have been reports by others of similar problems. Unfortunately that doesn't help me, or anyone else.
