If the answer is yes, then you need Proxomitron. It includes pre-made web filters that will suit most your needs. However there are hundreds more floating around the Internet and you can also create your own. The cool thing is you can control what aspects of a website you want to filter. With the latest beta version its also much easier to decide what pages you don't want to filter by simply dropping the URL's into the nominated text file.
Installation is easy.
You unzip the files into any directory you want and then run the program. Its got no registry entries and all files are contained in the one directory. Uninstalling is easy. Just delete the directory. However for those that can't live without an install program, you can also download a version of Proxomitron that comes with an installation program.
