  • Make sure you are logged on to Windows as Administrator

  • Download the Microsoft Security Essentials virus and spyware definition update file according to your OS from the following pages:

  • Click "Run" to install the update or "Save" to save it on your computer and run it later. If installing in a Windows Vista or Windows 7 environment you should right-click the file and select "Run as Administrator" and follow the next steps.

  • When the definition update is running, a dialog box showing the extraction progress will appear. After finishing, you can verify the update by opening Microsoft Security Essentials, clicking "Update" and examining the virus and spyware definitions status.
