FileDefense for Mac

FileDefense is a program that forms the first line of defence in file access. It is a set of programs that provide an easy interface to locking down files and making sure that unwanted access is not given to malicious scripts, applications and services on the your computer. FileDefense automatically alerts you when any program is accessing files and prompts you to accept or deny that access. To this end FileDefense provides security second to none, stopping virii, trojan horses, malicious scripts and network services from accessing personal information, passwords or any other data that they should not have access to without your permission.

Version 1.5 has new easier-to-use interface and automatically shows the location of the stopped application in question.
