YO Dave, I would suggest filtering these file extensions to help clean up a ton of crap. Go to TOOLS > OPTIONS > FILTERS > KEYWORDS and add these to block. .wma, .exe, .rar, .html, .com, .zip, .mov. After you add these to filter be sure to click apply and OK. If you decide later you don't want to block one or more of the extensions, you can go back and remove them from the filter. Try it youll like it.
