Anyone else have this issue on a clean install of the latest build of Windows 10?
Clicking on "Yes, I trust this publisher and want to run this app" does nothing and the app never gets market as trusted, hence Anti-Malware can't update.
What version of Endpoint Security?
What build of Windows 10?
It's Endpoint E80.90.5592 and Windows 10 version 1809.
SmartScreen is disabled. No other AV to effect.
I'm thinking a TAC case might be in order (for this and the other issue you've started a thread on).
I would recommend upgrade to Endpoint Security Client E80.90. I think this is supporting Feauture update for Windows 10 ver 1809.
