John McAfee launches product to protect against NSA surveillance British-born Mr McAfee, 68, revealed plans for his new product at the C2SV technology conference in San Jose, California. It has been called "Decentral" and would work by using smartphones and other devices to create small networks, measuring as little as a few city blocks, that could not be accessed by government agencies. Mr McAfee said the machine would cost less than $100 and if the US government bans its sale: "I'll sell it in England, Japan, the Third World. This is coming and cannot be stopped. He told an audience the machine could be used for "nefarious purposes" by criminals seeking to avoid detection, but so was the telephone. Mr McAfee made a fortune in the 1980s and 1990s from anti-virus software which bears his name. Last November he was living in Belize when his American neighbour Gregory Faull was shot dead. Mr McAfee was named as a "person of interest" but not a suspect in the case by Belize authorities who he said were corrupt and persecuting him. He went on the run and crossed the border to Guatemala where authorities deported him to the US.
