With the newest version of Comodo Firewall, a user cannot import a configuration file (.cfgx) or remove it. (General Settings/Configuration).
So if something happens to a person’s settings, they will not be able to import the file and fix it, instead one would likely have to uninstall, reinstall an earlier version of Comodo.
Message: ‘You cannot remove active configuration’.
I used to be able to import the configuration with an earlier version without that message.
Also the installation changes the registry key (LoadAppInit_DLLs) below from 0 to 1 which prevents some other software from running. I have to change it back to 0 to get the other program to work.
