A computer worm sent extreme right-wing messages to millions of computers over the weekend in what anti-virus experts said was a sign that spam has become a tool for propagandists, not just scam artists, reports Reuters. Infected computers sent a "staggering" amount of neo-Nazi messages worldwide, and they may be used again for future attacks. With German-language subject lines that translate to phrases like "Multicultural = multicriminal," the messages point to racist websites and news articles that could be used to support anti-immigrant views.
