Cleaning out your own computer's porn images and documents by means of a porn scan can be done quickly and easily by using a porn detection application. Many of these drive cleanup executables are set up to cleanup pornography off drives and bring back your hard disk speed. Porn file analysis programs are special purpose products designed to easily scan computers and delete unwanted videos and pictures cached in your computer system automatically. These applications often feature nudity detection for image and video testing, Quicktime format testing, hard disk cleaning plus more.

Nearly all pornography scanners deal with finding words in files and checking their contents. This is done by comparing key phrases with a known list of keyphrases collected for the purpose. Words of interest include obscene keywords implying incest or other hot topics; unacceptable topic matter such as racism related items, matter involving violence, text inciting hate or any such unacceptable items; patterns showing improper use; all of these can be detected and given as the obtained scan results and viewed as a group. Detected files can then be opened for further review by the operator, so that a decision is made about the ideal way of dealing with each and every file as you see fit.
