I use Guidescope (the next generation of Junkbuster),
www.guidescope.com, as an ad filter on my home network
and it works really well. You can set it up on one
computer and use it as a remote proxy. But it is a
proxy and you have to make sure it is either a
transparent proxy or each browser uses it as its
proxy.

I did try adding the squidguard blacklist to it, which
is thousands of sites, and the internet started
crawling. But I was running it on a Pentium I with 64
megs of memory, so your mileage might vary.

Probably the better way still would be combining Squid
with something else.

Squidguard is pretty nice and they even have a
prebuilt blacklist available:
http://www.squidguard.org/
http://www.squidguard.org/blacklist/

I also tried Ad Zapper and it could be extended too to
other things.

Anymore, my computer can't really handle squid and
something else, so I just log everything and yell at
the kids when I see something that isn't supposed to
be in there.

 I use it on a home PC and have had no trouble from
the software end. The tough part is setting up
regular expressions to filter content. You could just
use the straight "add all the URL's you want to
filter" approach, but then you have to maintain a lot
of URL's.
