In the final level of the game, Sepulveda traces the Viral infection back to its source, which is e-mail spam. After Sepulveda had accidentally flashed an image of his face across the skies of Darwinia, The Darwinians had assumed him to be God. They then re-aligned a portal inside Darwinia in an attempt to communicate with God. The Darwinians managed to access Sepulveda's computer, downloading several files and eventually downloading the Spam. The e-mails were infected with a very nasty strain of internet virus which corrupted the Darwinians. The player is tasked to destroying the few remaining e-mails.
