Microsoft Windows Malicious Software Removal Tool

The Microsoft Windows Malicious Software Removal Tool checks the computer for infections by specific, prevalent malicious software. This malicious software includes Blaster, Sasser, and Mydoom. Additionally, the tool helps remove any infection that it finds in the computer. If the computer has an infection, the tool notifies you after the computer restarts when you are installing Internet Explorer 7. If you do not receive notification about an infection, the tool did not find an infection.

The Windows Malicious Software Removal Tool only scans the computer one time during the installation of Internet Explorer 7. The tool does not provide continuous virus scanning. The tool only runs again if you download an update to the tool by using Windows Update or Microsoft Update, either through the Microsoft Web site or through Automatic Updates.
