John McAfee was no ordinary guy.
He established himself as a leader in the cybersecurity industry by creating one of the largest antivirus companies ever.
What happened next, though, is what truly propelled him into the public eye.
The American software mogul, who was born in Britain, did stints at NASA, Lockheed Martin, and Xerox before releasing McAfee VirusScan in 1987.
As a result of VirusScan, a multibillion dollar industry was born in the computer world. He finally sold the platform to technology giant Intel for more than $ 7.6 billion in 2011.
