John McAfee net worth: John McAfee is the former CEO of the anti-virus software company McAfee who has a net worth of $4 million. John McAfee's net worth was once north of $100 million, but he lost much of it thanks to bad investments and the 2008 global recession. McAfee founded the company that bears his name in 1987. He distinguished his software from competitors by giving it away for free but charging for technical support and some updates. This allowed McAfee to become the global leader in anti-virus software, a title the company still holds today. Eventually, McAfee got bored with the software business and sold his entire stake in the company for $100 million. A series of bad investments, including a large bet on Lehman Brothers' bonds, cost McAfee millions and forced him to sell real estate and other assets for pennies on the dollar. For example, McAfee sold a $25 million Colorado estate for just $5.7 million. He also sold a mansion in Hawaii, a ranch in New Mexico and a Cessna private jet. Unfortunately the bad news did not stop with his financial troubles. With his remaining $4 million McAfee moved to Belize where the cost of living and taxes are much lower. On November 12, 2012, police in Belize announced that McAfee was the prime suspect in the murder of a man named Gregory Faull.
