It isn't so much the program that doesn't work, the problem is any program that attracts the attention of the Hardened Mode (HM) - when you click the Add an exception, it isn't being added to the Hardened Mode exceptions.
In my case it is an executable within the Outpost Firewall Pro 9.1, feedback.exe which is getting constantly pinged. See image of HM alert popup and note the path format the old 8.3 file/path format style. I'm not sure if this would have anything to do with it, but I rather doubt that.
Previously manually adding the full path didn't work, as soon as you added it and closed the interface (it was gone when you opened the exceptions again). This part action now appears to be working - but for obvious reasons, I don't want to do that as I'm hoping that eventually the Add an exception in the alert window functions as it should.
Shouldn't all of these HM alert popup stats/information be being uploaded to avast under the Community IQ ?
