I think you can't reverse. Your son most likely used the "clear history" feature of your computer.

He's probably clearing his history. The boy seems smart though, so he's probably doing whatever - if he's doing anything at all, let's not all start assuming here - when no one else is around. So unless you instal some software to moniter no matter his internet movements, you can't really do anything. At least that I know of. But again, maybe he just likes his privacy and deletes his history - I know I do, and I don't much do anything wrong.

Well, in Internet Explorer you go to "tools" on the toolbar, then "internet options". two thirds of the way down it clears the history after a certain number of days. You can set it to ten, or thirty, or what have you, and forbid him to change it. If he does, take away his privileges, same as you'd take away his car keys.

Press the Ctrl key and the H key at the same time, and it will bring up your history..Good Luck..

1) Are we talking about browser history or about Google history? http://www.google.com/history/welcome?hl=en&zx=t2QKAxEfng0 2) Anyway, it is normally possible for users to clean their history, if they know how to do it. But it seems that they don't just want you to know where they are going. You should talk with them about this. 3) "Filters can be implemented in many different ways: by a software program on a personal computer or by servers providing Internet access. Choosing an Internet service provider (ISP) that blocks objectionable material before it enters the home can help parents who worry about their children viewing objectionable content. Those who believe content-control software is useful may still not agree with certain ways it is used, or with mandatory general regulation of information. For example, many would disapprove of filtering viewpoints on moral or political issues, agreeing that this could become support for propaganda. Many would also find it unacceptable that an ISP, whether by law or by the ISP's own choice, should deploy such software without allowing the users to disable the filtering for their own connections. In addition, some argue that using content-control software may violate sections 13 and 17 of the Convention on the Rights of the Child."

Ctrl & H

As others have said, press ctr-H. If you think he's looking at porn, let him. It's only natural for any child who's in adolescence (or past that) to be curious about this form of entertainment. If you're worried about his attitude towards women and sexuality, then rest assured that the influence of yourself and your husband in that area eclipses that of any form of digital media.

Download a "keylogger" go for freeware, it can be installed invisibly and you can can check every keystroke the teen has pressed, it will pick up passwords as well. It's a bit drastic, but if you ARE concerned then it is one way to go. There is also a free programme called NAOMI (I think) and it restricts internet access, it will be less intrusive.....DO NOT forget your Naomi password otherwise you will have problems. Good luck :o)
