Encountered in the Series V episode "Quarantine", a holo-virus is a form of computer virus that affects holograms in the same way that another virus would attack humans. Dr Hildegard Lanstrom was infected and killed by the holo-virus, while Arnold Rimmer narrowly avoided the same fate. The psychic abilities manifested by those infected with the holo-virus include telepathy, telekinesis and hex vision, an energy weapon that shoots death rays from the hologram's eyes.
