John David McAfee, the founder of the antivirus software maker bearing his name, died in a prison in Spain on Wednesday June 23 2021, after a Spanish court said he could be extradited to the United States on tax-evasion charges. His death was confirmed by his lawyers. He was 75. He founded what is now McAfee Inc., the antivirus giant, which provides encryption and firewall services around the world. He left the company in 1994. Worked for Lockheed until 1987, then ventured into the antivirus business. After taking McAfee Inc. public in 1992 , John McAfee founded a new company, Tribal Voice, and released a social networking/chat product called PowWow. McAfee sold out of Tribal Voice, and it has since folded. For a time he was practicing and teaching yoga in the United States, but he has since moved to Belize. Before his troubles with U.S. federal law enforcement, Mr. McAfee was at the center of a media frenzy surrounding the death of a neighbor in Belize. Mr. McAfee was arrested on charges of illegally entering Guatemala, where he had sought political asylum. In October 2020, the Securities and Exchange Commission accused Mr. McAfee of promoting initial coin offerings — deals for cryptocurrencies — on Twitter without disclosing that he had been paid to do so. Mr. McAfee’s fortune had fallen to $4 million from $100 million, forcing him to auction off major assets. BA Mathematics, Roanoke College (1967)
