A threat to the users of Windows XP, Windows Server 2003 and Windows 2000 can get infected simply by viewing a web page. If you use Vista or Windows Server 2008, you’re safe.The infection occurs when the Direct Show component of Windows process a malicious Quick Time video file. The easiest way for the malicious file to get on your computer is via a web browser (not just Internet Explorer) but it can also arrive via email, shared network folders, sneaker-net, etc.There is no fix to this problem as yet but Microsoft does have a work-around – a registry zap that breaks the association between Quick Time files and Direct Show. That is, you can tell the operating system not to invoke Direct Show to process Quick Time files.The best possible work-around is one recommended in a CHEAT SHEET.
