Program to block websites and chat, which is the best

--- My teacher is in trouble with the college students, those with visits to sex sites and chat, he is trying to install a soft bloquei all this, I've heard of Zone Alarm, this is it good ---

The zone alarm good eh! the only thing I like about him eh naum because I think he's a bit complicated for more complex tasks! Use the Norton2002 because I think its very easy to use!

--- But I remember, ZoneAlarm does not block sites by subject. Blocks browser entirely, yes (which is not useful in this case).
There are programs to contain the access by topic, such as CyberGuard (I think this is). But if I'm not mistaken, tb Norton Firewall does the job. But I think you better check out a program that blocks proxy sites proxy server, cause it will not do to have the program installed on each workstation being qq that kid will have access to undo the adjustments.
Give a sought at tucows.com and download.com for monitoring programs, but the best way is qq your college book a budget for IT acquisition program. --- Help me
