Thanks for the reply kinemitor.
The thing is that in “Execution Control Settings” I have chosen to have all unrecognized files blocked. This means I could not even run Notepad before adding it to Trusted Files (which then is added to the Computer Security Policy I suppose).
So nothing can run without my approval, period. That’s how I like it.
What I don’t get is why the Comodo installer is not prevented from running when everything else is.
Thanks again, that could explain it. Except I have just deleted Comodo from the list of Trusted Software Vendors and tried the installer again. It still runs!
I have also previously deleted every single entry on the list of Trusted Software Vendors but for some reason they are automatically added again without my approval.
EricJH has previously stated that to disable all whitelisting I simply need to use the Paranoid Mode: https://forums.comodo.com/empty-t59650.0.html
But I guess that was for the previous version. Perhaps I should simple continue that thread. I really hope the possibility to disable all whitelisting still exists.
