Anti-virus software entrepreneur John McAfee has been found dead in a Barcelona prison cell. This comes hours after a Spanish court agreed to extradite him to the US to face tax evasion charges. The Catalan Justice Department said prison medics tried to resuscitate him, but were not successful, reported BBC. It said in a statement that "everything indicates" McAfee took his own life. A controversial figure in the tech world, his company released the first commercial anti-virus software. McAfee VirusScan helped to spark a multi-billion dollar industry in the computer world & was eventually sold to technology giant Intel for more than $7.6bn (£4.7bn). In October 2020, John McAfee was arrested in Spain when he was about to board a plane to Turkey. He was accused of failing to file tax returns for four years, despite earning millions from consulting work, speaking engagements, crypto-currencies and selling the rights to his life story, reported BBC.
