I recently installed Comodo CIS, however occasionally my system locks up since I did.
It completely freezes with a loud beep, and I have to use the shutdown button on my laptop
to reboot. I noticed on a video streaming chat last night after the computer locked up again I could
still hear the audio of the chat going on… I don’t know if this helps in determining what the problem is or not.
I looked in the administrative logs and could see where the system shut down unexpectedly but nothing about what could have caused it in any of the error logs.
Anyone else have this problem they resolved or any idea what could be causing this ? or what program I could run that logs events more thoroughly to give me an idea of what would be happening before the computer locks up ?
It only began when I installed comodo (after uninstalling Online Armor++) I had not had this problem before.
Comodo logs are the place to look. Firewall, defense+, antivirus.
I bet you find the answer in defense+. (If the log wasnt “freezed” too, while creating the entry)
Also make sure that there are no left overs of previously uninstalled security programs around. Not all uninstallers do a proper job. And left over applications, drivers or services can cause all sort of “interesting effects”.
Try using removal tools for those programs to remove them. Here is a list of removal tools for common av programs: ESET Knowledgebase .
Thanks for the help, I had to go back to my former firewall for now, I just didnt have the time to do alot of hunting, I tried installing it twice, had the same problem, a beep with a system lockup.
Maybe its just incompatible with my laptop, I don’t know. Would have been nice though since it was far less laggy than my current firewall when trying to play online games.
A firewall shouldn’t cause lag in online games, maybe indicative of other problems with your system. Bad drivers, bad hardware, file or memory corruption, unstable overclock.
