Sometimes it just happens, you find porn files while websurfing. Or unsuitable items
might be received in emails, or other methods. If this ever comes about, discovering
unwanted files might offend the person using the computer and this could leave files
behind on the system. And now there are software products that can check disk resources
for disgusting inappropriate imagery residing on the PC. There a few good examples
of these tools, including Snitch content scanner, apparently is one of the
more effective tools available.
Without exception, these software tools execute analysis passes on the hard drive
including auto-testing images, testing movie files to see if they contain adult material,
checking text files against keyword lists, checking for the presence of pirated
MP3 audio files plus other tests for suspicious items. Just the image and movie tests
incorporate intelligent scanning and quickly show inappropriate files as separate
from typical photos.
The software vendor allows downloading of trial software - of course this is an advantage
because you can try out the software in your own time.
