no you can't remove them. Many of us would like to, and quite a few have tried, and none succeeded, to the best of my knowledge. They are a part of ROM that is loaded, and no file from ROM can be deleted from the device directly. Indirectly I can't comment on, due to lack of knowledge...... sorry, and good luck!
There are no stupid questions, only a whole lot of inquisitive idiots.
Stupidity should be painful.
