ZeroSpyware's Intrusion Detection system lets you control access to the sensitive segments of your operating system and browser. These include the Windows HOSTS file, certain .INI files, the Run/Run Once/Startup program groups, the browser Home page, Search page, Favorites, and Layered Service Provider stack. Your system is constantly monitored for possible intrusions, and you are notified with clear, accurate details the moment an intrusion is attempted. ZeroSpyware takes the guesswork out of these critical decisions, and empowers you to quickly choose the right action.

A unique feature of this system is the Startup Manager that lets you keep track of applications that run automatically during startup. With this tool, you can actually add or delete applications in the Startup menu according to your personal preference.
