“I've been called 'paranoid,' 'schizophrenic,' 'the wild child of Silicon Valley.'”

John McAfee was a British and American computer programmer, businessman, and two-time U.S. presidential candidate. He is known for creating the first commercial anti-virus software and for founding McAfee Associates, the company built around it. In 1987, he wrote the software that made his name familiar in computing. He resigned from McAfee Associates in 1994 and later sold his remaining stake. In later years, he became one of the company’s sharpest critics, urging people to remove its anti-virus product and objecting to the continued use of his name in its branding.
