Internet Adult (illegal) Content Filtering - request for opinion

Hi All, Internet Illegal content viewing has always been an issue for corporate organisations. Even a properly configured proxy server will not deny someone receiving porn content through a web based email account. Eventually, such content viewing during office hours leads to decrease in productivity. :) In searching for a solution to such a problem, I recently came across a software called "iCom Stealth". However, intelligence regarding both this software and its developing organisation is obscure. No address or contact details exist for that organisation. Besides, this software is free as the organisation believes "that this kind of software should be free." And since I am not very proficient at reverse engineering, it's quite difficult for me to determine what's going on behind the code. The software is very easy to install and does NOT allow for "ANY" option at all. You just have to install it. Under W2k, it runs a service named "thdetr.exe" which uses approximately 4MB of RAM. In their FAQ, this organisation has included the following: "Our filter relies on our unique artificial intelligence system, composed of the IPR (Intelligent Pattern Recognition) engine, and the AMS (Application Monitoring System). Just blocking a domain is not enough if the user knows how to mask or hide the blocked data. That's why we opted for this solution. Our software will NEVER connect to any site, and will not gather and/or disclose any kind of personal information." This is how the software works. Whenever an illegal content is being viewed (either from a site or a web-based email site), the content starts to load in the Internet Explorer window but IE closes after 1 or 2 seconds. If you try to access the same site again, the same thing happens. The page loads and then the IE window closes. I have not tested this software with any other browser apart from IE. Please note that this software also works if obscene language is used on MIRC and yahoo messenger. The software is really effective, but as i mentioned, you never know when some malicious code is running in the background. Here's the link to their site. http://members.lycos.fr/primefilter/ I am generally very prudent in using freeware, and i tend to extensively research on the product and organisation and seeking third party opinions before using it. But this one, though it is very effective, is at the same time very obscure. Does anyone have any idea/opinion about this software? Thanks. Karmil
