I saw Bluetooth in startup applications and disabled it, but the process is still run when I boot the system.
Edit 1 i disabled it via BUM, and still appear in bootchart, look at this https://docs.google.com/file/d/0BwS0_GGz-wuDYkc5S2p2Y1JyYnM/edit?usp=sharing and most of services that i disabled via BUM
Edit 2 I uninstalled it before via ubuntu software center, but reinstalled automatically when update system
