John David McAfee (born September 18, 1945) is an American computer programmer, businessman, and politician who sought the Libertarian Party nomination for President of the United States in the 2016 election, which was won by former New Mexico governor Gary Johnson. He is the developer of the first commercial anti-virus program. This bore the McAfee brand-name for years, until it was bought by Intel and given the Intel name. His wealth peaked at $100 million, before his investments suffered in the global crisis of 2007. McAfee also has interests in smartphone apps, yoga, and all-natural antibiotics. He resided for a number of years in Belize, but after several disputes with the authorities in Belize and Guatemala, he returned to the United States in 2013.
