Some people maybe got this problems when they want to lauch Blender.exe.
Every time the launch still to be approuved by Comodo, annoying at least ! :-\
This problems persist even you tell to Comodo that you agree it ???, and this because Blender.exe control another process inside : Blender-app.exe (the real laucher).
For avoid that, you have to put a rules in the Behaviour Blocker :
>>>Lauch the apps you want to rules.
- find Defense+ in Comodo tabs;
- check Define exceptions and go to it >Exceptions (a new window should open);
- RMB (right clic) >Add >Active process ; select your apps in the list – clic OK;
- now your apps is in the Exception window – clic OK
You’re the boss 8)
