My 17yo son seems to be an internet addict, mainly of video games and general entertainment sites, although he denies it. What I would like to do is monitor his computer use for a period of time, without his knowledge, and then confront him with the results. I don't want to pry, just to show him how many hours he has spent on entertainment in comparison to his study time.

As someone said elsewhere, monitoring secretly is like reading your kid's diary. However if I do inform him in advance he will be outraged and work around it - he is technically savvy and we have several computers in the house. If there is software which monitors websites visited only - no filtering, no keylogging - the intrusion will be minimal and it is not as if he has not been warned.

It is important that that the software is not capable of intruding into his privacy and does not lag his speedy 64-bit computer, which he will certainly detect on video games. If i catch him viewing porn sites, well it was never my intention.

Does anyone know of monitoring software which monitors websites visited only?
