ZeroSpyware Free Edition provides comprehensive spyware removal and protection, with an easy-to-use interface. An intelligent scan engine finds and removes all forms of malware that may be hiding in your computer. Intrusion detection systems constantly monitor sensitive operating system and browser areas, alerting you if suspicious activity is detected, and blocking unwanted changes to your computer. ZeroSpyware provides real-time protection with automated discovery, a feature that identifies all active applications on your computer, and automatically suspends any that are identified as spyware from a long list of known security threats. Potential threats are automatically reported to Spyware-Net, the ZeroSpyware online information resource.
