MADRID (AP) — John McAfee, the creator of the McAfee antivirus software, has been found dead in his cell in a jail near Barcelona, a government official has told The Associated Press. Authorities did not disclose the cause of death. Earlier Wednesday, a Spanish court issued a preliminary ruling in favor of his extradition to the United States to face tax-related criminal charges. Security personnel at the Brians 2 penitentiary near the northeastern Spanish city tried to revive McAfee, who was 75, but the jail’s medical team finally certified his death, the regional Catalan government said.
