The Total security 2017 (2016 as well) is blocking different services and does not show any popup or whatever to let you know that something was just blocked and therefore it is just possible to disable different modules one after another to see which one actually blocked the app/service.
I have had that problem for some time and tonight I decided to remove the Bitdefender and bang! All problems gone.
I was trying to enable Chrome remote desktop connection on my pc and the service was blocked with no notice from Bitdefender app. The remote connection service couldn't be established.
Could you guys add any popup that would let us know that an app is being blocked and so we can decide if it should be blocked or not?
