Desktop freez with Comodo firewal 5.x und Windows 7 Ultimate x64
What you did:
When an application is run for which no firewall rule exists the firewall freezes the desktop on the 4th or 5th popup
What actually happened or you actually saw:
A frozen desktop without an alert box
What you expected to happen or see:
An alert box
How you tried to fix it & what happened:
Removed the predefined “trusted vendors” list → turned down the frequency of freezes. Tried to define rules for every app before i run it → less freezes. Turn off the Defense → almost no freezes
5-6 don’t apply
Whether you can make the problem happen again, and if so exact steps to make it happen:
At least i think the problem is associated with “unknown” applications. Coded an app with defined behaviour that steps through the different defense mechanisms/subrules (keyboard access, protected registry-keys, etc.) The logs show that the application can do 4-6 pop-up generating tasks before Comodo Firewall freezes the system.
Any other information (eg your guess regarding the cause, with reasons):
Crash or freeze dump file: The firewall logs are missing the last 10 minutes before a freeze. W7 doesn’t generate logs.

We would very much appreciate it if you would edit your first post to create an issue report in line with the bug forum guidelines and format here. You can copy and paste the format from this topic.
To understand the reasons why we ask you to follow these guidelines please see below.
WHY WE ASK YOU TO FOLLOW THESE GUIDELINES
Bugs/issues can be impossible or very time consuming to fix if developers don’t have enough information to reproduce them. Since CIS is free, development time is limited. So if you want your issue fixed, please use the format below to describe it.
To avoid clutter, issues not described in the format below your post will not be moved to the ‘moderator verified’ issues topic. This means that the developers may not look at it.
Some of the features just cannot simply turn OFF like “Sandbox” and “Defense+”. They will hang the computer also whenever I run some of my games.
That’s so terrible BUG in the x64 edition on x64 Windows 7. But still never happen to Comodo Firewall 4.1.150349.920_x64 WHY ??
Currently I removed version 5.0.163652.1142_x64 and installed back the 4.1.150349.920_x64 on my Windows 7 Ultimate x64 edition. At least now my PC back to normal, no more hang no more abnormal behavior. Although there are some minor BUG available, but this can be easily counter. So it’s not a matter for me.
Will wait for at least 2 updates on the version 5. Then I will only install on my PC.
I’ll test a system run without eset on weekend (as i remember there has been a bug in the 3.x version of eset with the old version of the Comodo Firewall - but that caused a total block of internet connectivity on the local machine).
The test-application is based on some internal routines which i’ve developed in a team. When the other team-members agree i’ll post it. In more detail: you can tell the app which special action it should perform on a windows system, i.e. “get access to a registry key” or “try to resolve a domain name”. And then it does
I know it can be turned OFF. But when I turned OFF those 2 features and I run my game, my PC freeze.
So I have to let the features turned ON and then run my game. In my case, I’m seems being forced to use "Sandbox" and “Defense+”.
Unfortunally i’m not able to supply the test app. If there are questions for functionality (it functions the way that you can specify an action like “access a registry key” or “access memory”. Modified that to provoke several firewall/defense-popups for this app)
Tested this on a clean system, after reinstall on my computer, another computer x64/W7Ult. No change.
Unfortunately we do need this issue to be reported in the right format, and with all the information we have asked for, if we are to forward it to verified issues.
For the moment I am going to move it to the Orphaned/Resolved child board. If you do manage to edit your post to create a complete issue report in standard format, and PM an active mod, we will of course consider moving it to verified reports.
The devs only look at the Orphaned/Resolved board if they have time, so please do edit the post and PM an active mod if you want it fixed.
I had this same problem a couple of weeks ago. A keypress could take a few minutes to be recognised. I eventually spent about 4 hours waiting for key presses and mouse movements and eventually killed as many processes as possible until only cmdagent was still running, which I obviously couldn’t stop. I was unable to use the computer enough to uninstall Comodo so I did a fresh install of Win 7 Pro x64. Ran it for two days without Comodo with no problem, installed Comodo and was back to square one. I went through installing Windows and Comodo again to satisfy myself that Comodo was causing it. I have now been running Agnitum Outpost for two weeks with no problems. I’ll come back to Comodo when this problem is fixed.
