I use adzapper with squid, this has a good explanation
(note also the feedbacks mention a mistake in the body
of the article where the file ownership of 777 was wrong
and should be 755):
good instructions here

if you use ipcop or some other linux firewall distribution
(see
http://www.ipcop.org) with squid/adzapper, then the
firewall distribution can help strip out the ads and
replace them with a harmless icon/gif, I guess if you wanted
you could setup your own 1x1 gif picture and not even
see the substituted ad (adzapper sticks in a gif that says
"Ad Zapped"). This has the added benefit of speeding up
the network since you're not pulling some ad from a
remote server but getting a static placeholder image
from the local network (even that can be a tiny thumbnail
pic if you like). The firewall box then feeds your network
(even if they are windows boxes) as the green side,
the red side is the internet.
