At 11:34 A.M. Pacific Time on August 11, Microsoft began investigating a worm reported by Microsoft Product Support Services (PSS). A worm is a subclass of a virus that generally spreads without user action and distributes complete copies (possibly modified) of itself across networks. A worm can consume memory or network bandwidth, thus causing a computer to stop responding.
Update Several antivirus companies have responded and written tools to remove the Blaster worm.
