adobe updates. i don't understand your computer/adaptor setup, your computer is off but it's still ticking over data use? sometimes programs like that can only update when the connection is closed/computer is turned off...
Adobe updates was on, but I don't see where I can disable it from starting. I looked for a service but there wasn't any. I ended up closing the process. :: shrug ::
I'm also baffled as to how it could use ~450mb in about 15 minutes.
Updater has been disabled, although it still had updates to download so I'm skeptical that it was doing anything (unless it is just downloading the same thing over and over).
