I monitor all my installs (and fs usage), and can tell you there are no apps (outside the initial set) that I didn't install myself. I have about 40 apps showing in the app manager uninstall list, and to the one I've asked for each one to be installed. If you're seeing something being installed on your device that you didn't ask for, then something you've put on it is causing this behavior. It's not part of the base image from Nokia or Maemo. If it were, everyone would be seeing it.
