Well it's releasing a tool to remove about 17 viruses at least
Microsoft

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. New versions are available through this Web page, Windows Update, and the Microsoft Download Center.

* Users of all supported versions may run the tool directly from this Web page, or manually download the newest version to run locally on their computers.
* Windows XP users may get the latest version through Windows Update. To have the newest versions automatically delivered and installed as soon as they are released, set the Automatic Updates feature to Automatic.

Note The version of this tool delivered by Windows Update runs in the background and then deletes itself. If you would like to run this tool more than once a month, use the version on this Web page or install the version that is available in the 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 software to help protect your computer from other malicious software.

Don't forget you have to be using an admin account to run the tool Might come in handy for those people that have to fix peoples' computers once they are infected
