John McAfee

John David McAfee (/ˈmækəfiː/, MAK-ə-fee; 18 September 1945 – 23 June 2021) was a British and American computer programmer, businessman, and two-time U.S. presidential candidate who unsuccessfully sought the Libertarian Party nomination for president of the United States in 2016 and in 2020. In 1987, he wrote the first commercial anti-virus software, founding McAfee Associates to sell his creation. He resigned in 1994 and sold his remaining stake in the company. McAfee became the company's most vocal critic in later years, urging consumers to uninstall the company's anti-virus software, which he characterized as bloatware. He disavowed the company's continued use of his name in branding, a practice that has persisted in spite of a short-lived corporate rebrand attempt under Intel ownership.

McAfee's fortunes plummeted in the 2008 financial crisis. After leaving McAfee Associates, he founded the companies Tribal Voice (makers of the PowWow chat program), QuorumEx, and Future Tense Central, among others, and was involved in leadership positions in the companies Everykey, MGT Capital Investments, and Luxcore, among others. His personal and business interests included smartphone apps, cryptocurrency, yoga, light-sport aircraft and recreational drug use. He resided for multiple years in Belize but returned to the United States in 2013 while wanted in Belize for questioning on suspicion of murder.
