Cleaning hybris.worm-aka Snow White

Does anyone know how to clean the win32.hybris.b.worm? ( snow white ) This is my second infection. So far the only way we’ve found is format. Protector Plus Anti-Virus will detect it, but not disinfect it. Niether Norton nor McAfee will even detect it w/the updated DAT files. If anyone knows of a clean up, alot of people in my area will be greatful. Thanks!
