Bad Wolf virus

The Bad Wolf computer virus had erased all information on Rose Tyler from the Torchwood Institute database. (DW: Love & Monsters) This was presumably done by Rose Tyler as the Bad Wolf entity in The Parting of the Ways when she scattered the phrase Bad Wolf throughout space and time.


 * The Doctor had earlier offered Mickey Smith a computer disc containing a virus which, if activated, would erase all mention of The Doctor from the Internet. (DW: World War Three) A connection may or may not exist.
