We would not be able to confirm nor deny this because we do not have access to data about the application. However, one thing we can say is that it does open a window ahead of time and asks for permissions. If you are suspicious, close the software and ask yourself if your machine was really infected before you opened Steamunlocked again. Additionally, when exploring an executable file in your browser, look at the settings tab (usually in Adobe’s PDF reader) -you’ll see execution limitations which explain how certain functions are restricted in order to reduce vulnerability. These settings were made by developers as a way of opening secure executables on certain applications without allowing them any control or interaction on your computer beyond pre-determined restrictions.
