Windows Defender Definitions

Updated: October 23, 2007

Applies To: Windows Server 2008

Windows Defender uses definitions, also known as signatures, that contain information about spyware and other potentially unwanted software. All definitions are stored in a definition database and include the changes that are made by spyware and other potentially unwanted software to the operating system. This information is used to detect and remove spyware and other potentially unwanted software.


The following is a list of all aspects that are part of this managed entity:

Name Description

Definition Status

Definition, or signature, updates are released frequently and are designed to help protect computers from new threats. Windows Defender should have a definition database that is less than 14 days old. Old signatures can be used but they do not detect the latest threats.
