Antivirus Software founder John McAfee dies at 75 after being found in Spanish jail cell
John McAfee, a 75-year-old American who developed the first anti-virus software, died in a Spanish prison. He died just hours after a Spanish judge agreed to extradite McAfee to the United States in a tax evasion prosecution. McAfee appears to have committed suicide and evidence indicated that, according to prison officials. British-born U.S. technology entrepreneur John McAfee was indicted in Tennessee on tax evasion charges and was charged in a cryptocurrency fraud case in New York. Before developing the world's first commercial anti-virus in 1987, McAfee worked for NASA, Xerox, and Lockheed Martin.
