John David McAfee  (September 18, 1945 – June 23, 2021) was a British-American computer programmer, businessman, and perennial political candidate. He founded the software company McAfee Associates in 1987 and ran it until 1994, when he resigned from the company. McAfee Associates achieved early success as the creator of McAfee's first commercial antivirus software, and the business now produces a range of enterprise security software. 
The company was purchased by Intel in 2011, though it still bears the McAfee brand name. 
McAfee's wealth peaked in 2007 at $100 million, before his investments plummeted in the financial crisis of 2007–2008.
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, and herbal antibiotics.
McAfee was also a political activist. He unsuccessfully sought the Libertarian Party nomination for president of the United States in 2016 and 2020.
On October 6, 2020, McAfee was arrested in Spain over tax evasion charges.[8] The charges were announced shortly after the U.S. Securities and Exchange Commission revealed that it had brought civil charges against McAfee and that he could face 30 years in prison if convicted in the criminal matter.
