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 50 ways spyware can enter your PC. The worldwide SpyNet™ community plays a key role in determining which suspicious programs are classified as spyware. Microsoft researchers quickly develop methods to counteract these threats, which are automatically downloaded to your PC, so you stay up-to-date. The user must be an administrator to install this application. Current Giant AntiSpyware users with active subscriptions are advised to continue to use their existing software. Windows AntiSpyware may prompt you to remove some peer-to-peer (P2P) file sharing programs. If you choose to remove such a program, Microsoft Windows AntiSpyware deletes the entire contents of the Program Files directory that relates to the P2P program. Because some P2P programs store downloaded files in a default directory under Program Files, this might remove all files downloaded through the file-sharing program. For example, KaZaA stores .exe and .dll files at C:Program FilesKazaa. Downloaded files are stored at C:Program FilesKazaaMy Shared Folder. If you use Windows AntiSpyware to remove KaZaA, all files and folders under C:Program FilesKazaa are removed. If you have installed any P2P file sharing programs, we recommend that you make a backup copy of your downloaded files before running Windows AntiSpyware.
