Strange MySQL Popup "Mysql Installer is running community mode"

I have installed a recent community version of MySQL from MySQL site. The version is `5.6.x`. It was done using an installer and I also chose the option to create a MySQL service on Windows so that I can simply start the service. The service was set to not start automatically. Although I am not actively using MySQL, while I am working on my PC on something else, a strange pop-up displays, > MySQL Running in community mode. Does something, prints on screen, and closes:  I am surprised to see this and wonder: what is it doing - connecting to a remote server and doing what? Does someone know the internals and how to prevent it from connecting to a remote server? Could this be a security issue?
