Your .BIN file is associated with VLC (an awesome free video player, for those who are unaware) because you chose VLC as the default program for .BIN files when you installed it. That's the default choice during installation b/c some .BIN files are video files. But you don't want VLC to open this file b/c it's an archive and not a video.
The easiest way of correcting this is probably to just uninstall VLC and then reinstall it, taking care to deselect .BIN files from the list of files that VLC will associate itself as the default program. Actually, it makes the most sense to update your firmware in between uninstalling and reinstalling VLC.
