Internet Junkbuster
The Internet Junkbuster [1] (http://internet.junkbuster.com/) is a web proxy[?] that can block ads and cookies. It was developed by the Junkbusters Corporation[?] and released under the GPL. However, the Internet Junkbuster hasn't been updated since 1998.
Privoxy is an up-to-date filtering proxy based on the Junkbuster code, but it is much more powerful. See also the Proxomitron, a Windows-based web filter.
