Armageddon virus
From Tardis Wiki, the free Doctor Who reference
The Armageddon virus was a computer virus that at some point before 2009 a group of Earth cyberterrorists used to bring down the entire international banking network. They were stopped by the FBI however, and after this the unusualy potent virus apparently circulated under security experts. When a Xylok known as Mr Smith tried to destroy the Earth, Alan Jackson was able to use this virus to wipe the mind of the chrystaline lifeform clean. (SJA: The Lost Boy)
