Something possible happened with the install causing some form of corruption with the installation.
I would consider doing a complete uninstall re-install with a new installer. Download here
You can find some good recommendations in Chirons post here about reinstalling and a good configuration link at the bottom of his post.
seems to be a common error I followed these links from the avira forum. Did you change any settings in CIS?
I would say try uninstalling CIS using revo uninstaller free. Then reboot. After that try running Eusing registry cleaner. Clean and reboot. Then install CIS again and tell me if the error is still there.
Since you’re running 64 bit Revo Uninstaller Free will not be able to uninstall it.
What I would recommend, and I apologize if you have already tried this, is to first uninstall it normally. Then restart the computer. Also, make sure that there are no other security products currently installed on your computer.
Then run the cleanup tool for CIS. Once it’s done restart, then run it again and restart the computer when it’s done.
After that go to here and run the uninstaller for any security products which you have had on your computer in the past. If you installed a security product and it’s uninstaller is not in the list please let us know and we’ll try to find it.
Once you’re done running these restart the computer.
Then run a scan with Eusing Registry cleaner and remove anything it finds.
Then restart the computer. After it starts up again install CIS again. Then configure it as I recommend here. Do not change any other settings.
Okay, I checked with MBAM, Hitman and CCE and I am 100% confident that I have no malware on my system.
I completely followed Chiron’s steps and am still getting the error.
I found out I can trigger the error by simply clicking “check for updates” from the “More” tab.
If I run the actual exe cfpupdat.exe file from the Program Files, it run’s without error. It’s only when I click check for updates from the GUI.
I have temporarily “stopped” the alerts by disabling “automatically check for program updates” so hopefully my Virus Definitions will still update while that is deselected.
Try to turn on Windows Event Logger in your system services. To do that, you can just open the start menu and type in “services”. Select “Services” with the little gear icon. When it opens, scroll down to “Windows Event Log”. If it’s stopped, try to start it.
The 0xc0000409 error may be caused by windows system files damage. The corrupted system files entries can be a real threat to the well being of your computer.
There can be many events which may have resulted in the system files errors. An incomplete installation, an incomplete uninstall, improper deletion of applications or hardware. It can also be caused if your computer is recovered from a virus or adware/spyware attack or by an improper shutdown of the computer. All the above actives may result in the deletion or corruption of the entries in the windows system files. This corrupted system file will lead to the missing and wrongly linked information and files needed for the proper working of the application.
Will disabling “automatically check for program updates” also disable the Virus Definition updates? If that’s the case I’ll just go back to Avast I suppose. Program updates arn’t that important to me and I’ll just check every so often.
Reporting of bugs is strictly moderated to make sure Comodo gets clear bug reports. So, please make sure you closely follow protocol. That way your report will certainly be seen by Comodo staff.
My help topic was closed and I really wanted to share with you how I fixed my issue so I will make this thread. Sorry if this is not allowed.
So it turned out that Comodo’s THEME caused the issue I was experiencing. I was desperate to try anything to fix it so I decided to go thru all the themes since I noticed the issue only happened with the GUI.
Turns out that switching Comodo’s theme to “Windows Default” 100% fixes the issue!
Every theme with “COMODO” in the name gave the same error.
What a strange bug? I wonder why my computer reacted this way?
Anyways, thanks for everyone that tried to help me and cheers for CIS!
