Microsoft Malicious Software Removal Tool

The Microsoft Windows Malicious Software Removal Tool checks computers running Windows XP, Windows 2000, and Windows Server 2003 for infections by specific, prevalent malicious software -- including Blaster, Sasser, and Mydoom -- and helps remove any infection found. When the detection and removal process is complete, the tool displays a report describing the outcome, including which, if any, malicious software was detected and removed. Microsoft releases an updated version of this tool on the second Tuesday of each month. You can run the tool from this Web page anytime or download it to your computer.
