This article describes how to download the latest beta malicious software (malware) definition update for Microsoft Forefront Client Security.
The latest beta malicious software definition update gives you early access to definitions for critical infections that the latest release version of the definitions does not detect or clean.
You can use these beta definitions to clean infected computers. You can also use these definitions to protect computers that are at an immediate risk of infection.
Microsoft offers a partially tested beta definition update that you can download before the fully tested version is available.The beta definition update is not meant for enterprise-wide deployment.
Beta definition updates are explicitly created for malicious software threats. You should not deploy a beta definition update if you are not experiencing a threat for which it was explicitly created.
Note After additional testing, certain beta packages will be released as regular signatures. The same binary file that was used for the beta malicious software definition may be used for the released definition.

Technical support for x64-based versions of Microsoft Windows
If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
