The Gwinnett Medical Center in Lawrenceville, Georgia, was hit by a “virus” infection that downed the institution’s network and sent staff back to using paper records. The source of the outbreak – not the first that has affected the hospital according to sources – is still not clear. A worm infection (for example by Conficker or Conficker) seems the most likely cause. In 2008, admissions systems at three hospitals in London had to be shut down after 4,700 computers became infected with Mytob worm.”]
