Alarmed by the program’s quick spread after its debut in November, computer security experts from industry, academia and government joined forces in a highly unusual collaboration. They decoded the program and developed antivirus software that erased it from millions of the computers. But Conficker’s persistence and sophistication has squelched the belief of many experts that such global computer infections are a thing of the past.
