Pictures From the Week in Business: Barbie, McAfee, Apple and More The antivirus software pioneer John McAfee was hospitalized briefly on Thursday after being denied political asylum in Guatemala, and his lawyers said they were making a last-ditch effort to keep him from being flown back to Belize for questioning about the killing of a fellow American expatriate. Asserting his innocence, Mr. McAfee became a multiplatform online dissident, with a Twitter account and a blog at whoismcafee.com with audio links, a comments section, photographs and a stream of invective against the government and the police of Belize. He has turned being a fugitive into a kind of high-tech performance art.
