John McAfee was a British-American information security pioneer who founded the global computer security software company McAfee. A highly influential figure in the field of computer security, he was a world renowned expert on internet surveillance, global hacking scandals and threats, and personal privacy. Born to an English woman and an American soldier in the 1940s, McAfee endured a difficult childhood. His father was an abusive alcoholic who committed suicide when John was 15 years old. In spite of his troubled childhood he proved to be a good student. However, he too became addicted to alcohol and drugs, and was prone to wild, eccentric behavior. He was working on his PhD when he got thrown out of the college for having a sexual relationship with a student he mentored. He later found a job as a programmer at NASA's Institute for Space Studies in New York City. A brilliant man, he easily found jobs at reputed organizations despite his bizarre behavior and addictions. After a series of jobs he put his entrepreneurial skills to good use and founded McAfee Associates, a computer anti-virus company which he later sold. His other business ventures include Tribal Voice and QuorumEx. In September 2015, he announced that he will run for the 2016 U.S. presidential election as a member of the newly-formed Cyber Party. He unsuccessfully sought the Libertarian Party nomination in the 2016 and 2020 US Presidential elections..
