Thanks to everyone who has pointed me in the right direction before. I now have Squid running as a Windows service, and have even managed to set it up to block adverts from certain advertising domains: http://pgl.yoyo.org/adservers/index.php#plaintext I would also like to set squid to refuse access to pornographic and illegal websites, and having googled a bit, it seems that SquidGuard is built for this very purpose. Is there a port if it for SquidNT? Can anyone advise me as to where I can get it, and where I can find instructions on how to set it up? If that isn't going to be possible, does anyone know of a maintained list of pornographic domains and illegal sites (broad range really), similar to the advertising blacklist found above, which I can get regularly and which can be used to block access to these sites? Thanks, Ben
