Even children can stumble onto obscene files while using the worldwide web. Or a user might bring in inappropriate items on a USB stick. In any case, discovering unwanted files can cause surprise or shock and conceivably it also can leave behind evidence of the activity that forensic tools could reveal. Products can be downloaded and installed that can search your harddisk for inappropriate naughty pictures that exist there on the computer that was used. One of the main contenders in this category of tools is Snitch content scanner, and if we can believe the talk, is one of the best.

Depending on the product being discussed, these tools scan storage resources using tests like previewing image files for obscenity, looking for porn content in movies, finding suspicious key words and phrases in files, seeing what users visit online and many more besides. Take for example the image and video analysis capabilities that make life easy by running 'porn testing' and quickly show inappropriate files as separate from typical photos.

A 30 day demo can be obtained from the website - giving ample opportunity to test the features prior to purchase.
