Abstract
Embodiments perform detection and prevention of unauthorized access to files in a target folder. A filter driver, interfacing with a target folder, intercepts a first request from a process to access a file in the target folder. The filter driver returns a virtual file, along with the existing files, to the process. Upon receiving a second request from the process to write to the virtual file, the filter driver designates the process as a hostile process and prevents further access attempts.
