Did you post a link to the correct thread, as the software in use by the user, doesn’t list any Comodo products? Although the dump file does mention cmdguard.
Your product seems to work fine with CIS, your company is also on the Trusted vendors list. Personally, I’d suggest the user has a problem with one too many security products installed simultaneously.
In your thread on the Anvisoft forum you also mentioned you have Avira Free and Spybot installed. As CIS works with the Anvisoft application, you’ll have to see which of the others is causing the problem. I’d suggest unistalling them one at a time and testing.
The only way you’re going to find out which application(s) is/are causing the problem is by uninstalling. Disabling applications at a high level doesn’t necessarily unload potentially conflicting drivers.
As you can clearly see from the image I posted above, CIS and the anvisoft product work together. Your problem is likely due to the fact you have several competing security applications installed. If you want to run CIS and the Anvirsoft application you need to find out which of the other security applications is causing the conflict.
From the information you have given I am not clear whether this is a bug/issue.
For the moment I will transfer you to help so you can work through this issue with users and mods in this forum and hopefully resolve it. I hope that is OK.
Please ask any mod to move this report back to the bugs forum if it becomes clear that it is a bug/issue.
