I installed battle.net a long time ago.
Every now and then I use spotlight to invoke it by pressing ⌘ + space + space and I start typing "battle" every time, the top hit is "Battle.net Beta Setup". I do not want to invoke the beta setup, in fact, I am not aware of the existence of these files on my computer, not sure how to search for them except by using spotlight, but there doesn't seem to be a way to find out where they are, and I am reluctant to click on them in case it starts up a setup program and interferes with my existing installations.
