I think there is a misunderstanding here. You don't need paranoid mode to get prompts from unrecognized processes. If you are not getting prompts from them, and HIPS is enabled and set to safe mode, then Comodo is broken. Uninstall, reboot, and reinstall. What you are seeing is not expected behavior. The only reason not to get prompts is if the process is sandboxed. Otherwise, you need to get prompts, or else you have almost no protection at all, and most malware will infect your system.
