You can see a list of some fake codec sites here (Warning: extremely graphic names in the domain names).
All of these sites foist on Zlob Fake Codecs and DNSChanger trojans by requiring the user to install a “required” component (Video ActiveX Object, a “special” codec, etc.) to view a video (probably always porn). These components are actually very dangerous trojans with rootkits.
The majority are named after celebrities. However, a couple are of note: blockbuster-video-cxb(dot)org and yahoo-video-sdge(dot)org.
Obviously, stay well clear of all of these sites…
