Here is another simple tool for Internet Explorer 8 called IE Commercial Remover for restricting ads. This tiny, portable tool will disables flash ads and other commercial ads appearing on your browser.
Actually this tool put a wide range of commercial sites on IE’s restricted zone sites list. So that no banner or other commercials (flash etc) will load from these sites
The application does NOT come with an installer (it is not required) - Simply run the file, and click on Add Filter to IE. You can remove that protection with a click too.
