preventing rygel from starting at boot time

[Udvarias Ur <udvarias1 gmail com>]

1. I like the 'Gnome' desktop. Especially 'gnome-flashback', because of
    it's small memory foot print.

2. I installed the entire 'Gnome desktop' on my system, mostly for the
    applets and a few of the utility applications.

3. Unbeknownst to me 'rygel' was installed and set up to start at boot
    time.

4. I use my system for communication and research, NOT entertainment.

5. After installing the 'Gnome desktop' on my system I noticed a
    significant decease in performance, and a huge amount of IO
    activity that I had NOT initiated.

6. I started investigating that performance degradation and
    unauthorized, by myself, IO activity, as it seemed that, in spite
    of all my efforts and clamav, that a virus had infected my system.

6. My investigations found that'rygel' is using an enormous amount of
     IO, and possibly other resources as well.

7. I do NOT have a great deal of bandwidth.

8. Even if I had an unlimited amount of bandwidth, my preference would
    be to allow SETI, or some scientific project inspired by it, to use
    some of the bandwidth, NOT some sort of seemingly entertainment
    oriented software. (Which, if necessary, I would want to be able to
    start and stop as needed. i.e. Load, when needed, and entirely
    remove from memory, when no longer needed.)

9. Removing 'rygel,' via Synaptic, will result in the removal of the
    entire 'Gnome' desktop.

10. The'rygel' man page contains *nothing* about how prevent it from
    being loaded at boot time.

11. Even 'rygel.conf' merely states …

        [general]
        # Set it to 'false' if you want to only use the streaming
        part of Rygel and/or don't want it to advertize itself
        on the UPnP network. If you want to completely disable
        rygel, just don't run it then. :)
        upnp-enabled=true

    However, the neither the man page nor the 'rygel.conf' file states
    HOW to '… just not run it …' even though the mere installation of
    it, sets it up to automatically run at boot time.

Why am I being forced to either stop or get rid of something that sets 
itself up to run at boot time, every time I start up my system, which I 
do not want running on my system at all. Was installed without my 
knowledge and hides. (Neither 'ps -A' nor 'top' show a process called 
rygel or containing that string.)

How can I stop 'rygel' from running at boot time without putting 'rygel 
--shutdown' into *startup applications*, which doesn't seem to work anyway.
