Which means there was some intended way to trigger running it. Perhaps Samsung's instructions or their menu system weren't clear and they managed to hide it from him. But there most definitely was an uninstall script, and if he had managed to find the intended button in the interface, it would have asked for admin permissions and then done all the cleanup for him. The very cleanup that he complained about having to do by hand.
I think you are probably right. Although, with a name like that it could be some post-install cleanup of temporary files (which would explain why it was doing chown, rather than rm, although there are certainly other options!).
