Back Orifice is a remote administration tool, which gives the system administrator privileges to remote attackers and allows them to do whatever they want on the affected PC. Back Orifice can hide itself as a component of any program installation and enter the corrupted PC without a computer user's permission and knowledge. Back Orifice can be attached to other system files or applications or run on its own. Back Orifice must be run by itself or by another software program. Back Orifice then installs itself and deletes the original application, then may run a specified program. You should uninstall Back Orifice as early as possible.
