As part of its ongoing efforts to address current and emerging security threats to computer users, Microsoft Corp. today announced two new technology solutions that will provide added protection against spyware and malicious software. Customers now can download the first beta version of Microsoft® Windows® AntiSpyware, a solution that will help protect Windows users from spyware and other potentially unwanted software. In addition, the Microsoft Windows malicious software removal tool, which complements traditional antivirus technologies by removing prevalent viruses and worms from a PC, will be available beginning Jan. 11, 2005. These solutions build on the advanced security technologies and proactive protection features of Windows XP Service Pack 2 (SP2), which help better safeguard computers from hackers, viruses and other security risks.

In January 2004 Microsoft released a series of removal tools, each of which targeted a single virus or worm and some of its variants. Collectively, these tools augmented existing antivirus protections by scanning more than 55 million PCs worldwide for viruses such as Blaster, MyDoom and Download.Ject. The new Microsoft Windows malicious software removal tool consolidates these existing removal tools into a single solution. The tool will be updated on the second Tuesday of each month as part of Microsoft's monthly software security update process to respond to new viruses, worms and variants.

Available at no charge, the Microsoft Windows malicious software removal tool is designed to augment traditional antivirus solutions to provide more complete protection against viruses, worms and variants. As with Microsoft's earlier removal tools, the new solution incorporates the knowledge and technology gained through Microsoft's acquisition of GeCAD Software in 2003.
