Content Filter Software

Out of the many computer cleaning applications available, drive cleaners can be loosely categorized into just a few classes. The first of these are the hard disk cleaners such as the free CCleaner software, that can clean hard drives, removing temp files, unused files and recover wasted space. Another distinct group is the privacy protection type, clean up internet tracks and get rid of the previously typed URLs from drop down lists stored as history within your browser records, including 'evidence' and 'privacy' cleanup tools. Another category is the 'porn eraser', which is specifically used to disclose the presence of pornography or many other undesirable files and assists the user in deletion of the ones that should not be there. One more group of drive cleaning tools is the data erasing program which overwrites deleted data remaining on the hard drive's slack space, permanently.

The world wide web reveals the depth of applications that can handle the issue of drive cleaning in their own style. One subgroup is the content filter, and there are a number of these to choose from on software and shareware sites. This is not the only function that these software tools can do, some can clean up free drive space, locate and remove porno files, find programs that are not properly licensed, and show where your disk space is being taken up.
