Content Cleaner (from Content Purity) is a little program that will remove any trace of those sessions when you mouse wanders into the darker side of the web.

It's a simple idea that is effectively executed, however I find the marketing of this product rather bizarre. Their website seems to refer to Content Cleaner as a parental control tool, and tries to make a case that pornography can accidentally find its way onto your pc ready to be found by a child.

Firstly, children are very unlikely to find adult images while scratching around a pc's internal files - they are much more likely to find them on the open web (which, let's face it is much more fun that looking at cached files!).

Secondly, let's get real gentlemen. Porn makes its way on to your computer when you go looking for it. It's not a sin (well actually, I guess it could be :), but it might be a good idea to remove it once in a while.

For those who need it, Content Cleaner is an effective and affordable tool at just $29.99.
