On the Caribbean island of Ambergris Caye, where McAfee has lived for about four years, residents say he is eccentric, impulsive, erratic and at times unstable, with a penchant for guns and young women.
He would often be seen with armed bodyguards, pistols tucked into his belt, and McAfee's neighbor had complained about the loud barking of dogs that guarded his exclusive beachside compound.
His run-in with authorities in Belize is a world away from a successful life in the United States, where he started McAfee Associates in 1989 and made millions of dollars developing the Internet anti-virus software that carries his name.
There was already a case against McAfee in Belize for possession of illegal firearms, and police had previously raided his property on suspicion he was running a lab to make illegal synthetic narcotics.
McAfee says he has been persecuted for refusing to donate money to politicians, that he loves Belize, and considers it his home.
