Again, in case your web browser doesn't have an ads blocking feature or it doens't work well either you don't know how to use it, here it comes a FREE (GPL) nice tool that acts like "web proxy", meaning it stays between the browser and the Internet and heuristically filters the ads from webpages.
Grab it here: http://bfilter.sourceforge.net
Heuristics means the software tries to recognize ads on its own, using "smart detection", instead relying on a blacklist. In theory this means zero configuration by you and the ability of getting new ads, from any unknown site, as they come.

Note: developers needed for the project!
