From Hyperdyne Software:
Snitch detects and removes adult images, movies, inappropriate Internet activity, profanity, and other unwanted material on your Windows based computer. Snitch uses a suite of optimized algorithms to search your hard drive and selectively target certain types of files, and display those which appear to be suspicious. Incorporates 'SkinScan' technology - an algorithm designed to scan the pictures on your computer and to help differentiate between normal images and images containing nudity. The results are sorted and displayed for viewing or interactive deletion. Snitch is also able to scan compressed files, check text-based files for offensive words in their content or filename, identify files with improper file extensions (ie. movies / images that have been hidden by renaming to be '.tmp' etc.), and to generally recover pornographic files of many types.
