Windows Defender x64
x64 is a free program that helps you stay productive by protecting your computer against pop-ups, slow performance and security threats caused by spyware and other potentially unwanted software. Windows Defender
no longer supports Windows
2000 as mainstream support ended in June 2005.
This is the most current release of Windows Defender
x64. If Windows Defender
informed you that an update is available, you are running an older version. We encourage you to upgrade to this version. You can check your version of Windows Defender

This release includes enhanced features that reflect ongoing input from customers, as well as Microsoft’s growing understanding of the malicious software landscape.
Specific features of Windows Defender
* A redesigned and simplified user interface – Incorporating feedback from our customers, the Windows Defender
UI has been redesigned to make common tasks easier to accomplish with a warning system that adapts alert levels according to the severity of a threat so that it is less intrusive overall, but still ensures the user does not miss the most urgent alerts.
* Improved detection and removal – Based on a new engine, Windows Defender
is able to detect and remove more threats posed by spyware and other potentially unwanted software. Real Time Protection has also been enhanced to better monitor key points in the operating system for changes.
* Protection for all users – Windows Defender
can be run by all users on a computer with or without administrative privileges. This ensures that all users on a computer are protected by Windows Defender
* Support for 64-bit platforms and accessibility - Windows Defender
supports accessibility and 64-bit platforms. Please be sure to use WindowsDefender
X64.msi for 64-bit platforms.

XP and Windows
Server 2003. Examples of valid support scenarios are installation, configuration, definition update, detection and removal errors. Please refer to the Windows Defender
support policy for more information.
