John McAfee, the antivirus software pioneer sought in connection with a murder in Belize, has apparently begun writing a blog that chronicles his efforts to hide from the police. The 67-year-old founder of the company that bears his name has been eluding the police for the past week, after the shooting death of his neighbor, whose body was discovered a week ago. Gregory Faull, a contractor and restaurant owner, had complained about McAfee's dogs as well as the technologist's armed security guards.
