NASA, Univac, Xerox, CSC, Booz Allen and Lockheed
McAfee was employed as a programmer by NASA's Institute for Space Studies in New York City from 1968 to 1970 working on the Apollo program. From there, he went to Univac as a software designer, and later to Xerox as an operating system architect. In 1978, he joined Computer Sciences Corporation as a software consultant. He worked for consulting firm Booz Allen Hamilton from 1980 to 1982.[18] In the 1980s, while employed by Lockheed, he received a copy of Brain, the first computer virus for the PC, and began developing software to combat viruses.[citation needed]
McAfee Associates
In 1987, McAfee founded McAfee Associates Inc., which sold his program, the first anti-virus software to market.[17] The company was incorporated in Delaware in 1992, and had its initial public offering the same year. In August 1993, John McAfee stepped down as chief executive, but remained with the company as the chief technical officer. He was succeeded by Bill Larson.[19] In 1994, he sold his remaining stake in the company.[20] He had no further involvement in its operations.[7]
After various mergers and ownership changes, Intel acquired McAfee in August 2010.[21] In January 2014, Intel announced that McAfee-related products would be marketed as Intel Security. McAfee expressed his pleasure at the name change, saying, "I am now everlastingly grateful to Intel for freeing me from this terrible association with the worst software on the planet."[22] The business was soon demerged, once more under the McAfee name.
