SpyDefense is a spyware, adware and malware scanner that inspects your file system, registry and memory for any present threats. It offers 3 different scan modes, including a custom scan option as well as Real-Time protection that can alert you when any malware is about to be installed and optionally block the installation. Other features include a scheduled scan option, automatic updates and scanhistory report. The program detected several false positives during our review, and would have removed Norton anti-virus signature files since it considered them to be of Trojan nature. SpyDefense isstill in beta testing. It offers a promising array of features but so far lacks reliable detectionand is not recommended as a primary choice of protection.
