Microsoft Safety Scanner

Microsoft has debuted a new tool to fight malware on your computer.  If you think you may have malware, you can go to their website and download the free tool that will scan your computer with the latest software to detect any malware infection.  It is always up to date because the download expires in 10 days.  After 10 days, you have to re-download the scanner and run again.  This ensures that you are scanning with the latest updated scanner.  It is free for all versions of Windows, including XP.  Try it out.
