What is more concerning is that the actual executable is not made by me and has nothing to do with Adrorium as it is the official Unity player. Adro related code is in the folder Adrorium_Data/Managed/some dlls. Seems like Unity has some answering to do :). Try using some online site that scans executables with many antiviruses to see if it is a norton thing. And if you still have doubts (as you should, online executables should only be run if obtained from official sources) run it in a vm or windows sandbox or under a burnable account.
