We're they free or bought? I'm not 100% certain but I believe if someone bought something on your account without your knowledge you could request a refund for them (this is off the top of my head if I am incorrect please correct me). If its free then you should be able to hide or remove the games by right clicking, going to manage and then choosing "Hide this game" or "Remove from account".

Did they download a game, or purchase it?

You can always just deinstall a downloaded game. You can get rid of a purchase only via refunds. You can get rid of F2P license by removing it from your library. You cannot get rid of a free promotion, or a redeemed key.
