I was looking for information on rooting the Canvas and all of a sudden found that I had 7 new apps...surprise! They were Apple Music, some game called Empire (huge at 101 mb), Yahoo Finance, Huff Post, Newsroom, Security Master (Cheetah Mobile, perhaps), and Yahoo Mail. How the heck did that happen? Right about the same time, Google was trying to force an unwanted update which I hope I was able to cancel in time. Are they somehow related? I deleted them, but I how can I make sure they won't reappear?
