Windows AntiSpyware (Beta) is a security technology that helps protect Windows users from spyware and other potentially unwanted software.

Known spyware on your PC can be detected and removed.

This helps reduce negative effects caused by spyware including slow PC performance, annoying pop-up ads, unwanted changes to Internet settings, and unauthorized use of your private information. Continuous protection improves Internet browsing safety by guarding over fifty (50) ways spyware can enter your PC.

Participants in the worldwide SpyNet™ community play a key role in determining which suspicious programs are classified as spyware. Microsoft researchers quickly develop methods to counteract these threats, and updates are automatically downloaded to your PC so you stay up to date.

Beta 1 Versions

Since releasing Windows AntiSpyware (Beta) on January 6, 2005 (Build 1.0.501), we have continued to receive feedback from customers. We introduced a first beta refresh on February 16, 2005 (Build 1.0.509) which enhanced some of the real-time protection agents, added new threat categories, and improved stability and performance.

In this second beta refresh (Build 1.0.614), we’ve made other enhancements to the detection and removal capabilities, including improved Winsock LSP removal capabilities and support for long descriptions of categorized software. In addition, we have also extended the Windows AntiSpyware beta expiration date to December 31, 2005.

Existing users of the beta (Builds 1.0.501 and 1.0.509) will receive a software update that extends the expiration date and includes the enhancements to the detection and removal capabilities. The second beta refresh is also available for download through this site.
