For the software security pioneer, the end will come only if he's arrested or he gets away from corrupt officials.

"Get away doesn't mean leave the country. It means they will, No. 1, find the murderer of Mr. Faull and, No. 2, the people of this country -- who are by and large terrified to speak out -- start speaking out," he said.

McAfee founded his namesake computer security software in 1987, running it initially out of his home in California. He sold his stake in McAfee Associates in 1994.

A 2009 story in the New York Times indicated his fortune had plunged to $4 million from its $100 million peak, due largely to the real estate and stock market crashes that hit his investments.

McAfee moved to Belize in 2008. And in February 2010, he started QuorumEx, which claims on its website to be trying to "re-invent the way modern medicine combats and disarms pathogenic bacteria."
