The Microsoft Windows Malicious Software Removal Tool checks computers running:
- Windows Vista;
- Windows XP;
- Windows 2000;
- 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.
Having an anti-virus program installed and by running this tool occasionally, will help you achieve some effective results on some prominent malicious software that attacks your computer.
This software tool deals with malware differently than anti-virus software, because it removes the most prominent malicious software from a PC that is infected and actively running on a PC. Anti-Virus software is good at the quarantine of a malicious program, but sometimes cannot remove it completely form an infected computer.
Microsoft releases an updated version of this tool on the second Tuesday of each month, and as needed to respond to security incidents. The tool is available from Microsoft Update, Windows Update and the Microsoft Download Center.
Because computers can appear to function normally when infected, Microsoft advises you to run this tool even if your computer seems to be fine. You should also use up-to-date antivirus
