From the developer:
FileDefense is a utility that provides an easy-to-use interface to lock down files and ensure any unwanted access on your computer is not permitted. It stops viruses, worms, trojan horses, malicious scripts and network services from accessing personal information, passwords or any other data without your permission. When a program unknown to FileDefense is accessing files, FileDefense automatically alerts you to accept or deny the activity.
