I'm trying to find a way to control and restrict internet access for
some computers like blocking MSN and Yahoo Messenger and certain
websites. I posted a question about that but didn't get any answer,
but in the comments someone suggested CCProxy so i downloaded it from
youngzsoft.net and ran it. i read the installation instruction on the
website but i have no idea what i'm doing.

we share internet access on a LAN, it's basically 4 computers
connected to a 4 port modem (Alcatel Speedtouch).
what i need to do is  limit internet access for some users, and i have
no idea how to do that. please help !!

I used CCProxy a long time some years ago before switching to a
wireless router and found that the company is fairly receptive and
promptly responsive to emails when you're in a jam. They are Eastern
European if memory serves me correctly and there was occassionally
some problem with the language barrier with the support team but other
than that they seemed pretty helpful to me. If I were you I'd email
them with my question.

I did e-mail them with my question but unfortunately did not get any response.
