This question already has an answer here:
Steam, among other annoying things, seems to add games to my library spontaneously. For example, it recently added the game "Contagion - 2 hours left" to my library which I have no interest in installing and I cannot figure out how to get rid of it.
Also, they tricked me by suggesting that there was some kind of "free" deal over the Labor Day weekend for getting a free copy of Call of Duty: Ghosts, but of course, after I spend 4 hours downloading it and try to click the "Ready to Play" button, it announces "Failed to Start (no licenses)".
How can I get this junk out of my library?
