http://sunbeltblog.blogspot.com/2008/01/new-fake-codec-site-windows-and-mac.htmlI have already mailed a copy of the Mac Variant to Alwil from the chest.
Interesting thing is if you download some of the older variants of the trojan they are all detected as W32 malware and not OS X Malware.
Also since its clear that the malware authors are making numerous variants of thim mabye some kind of generic detection for it on both platforms?
