John McAfee -- AntiVirus Millionaire ARRESTED in Guatemala

John McAfee -- the millionaire who created McAfee Antivirus software -- was arrested in Guatemala yesterday for entering the country illegally ... while still considered a "person of interest" in a murder case in Belize.

According to reports, Guatemalan officials -- along with Interpol agents -- detained 67-year-old McAfee at a hotel in an upscale part of Guatemala City.

McAfee has been on the lam ever since he was named a person of interest in the murder of his neighbor in Belize -- where McAfee had been living for several years.
