There's also seems to be a massive sql injection attack inserting malicious code that automatically redirect users without their consent to this malicious file or other similar swf files.
So my friends be careful out there in cyberspace and don't visit untrusted websites. Update your anti-virus software and if possible I would suggest setting a killbit for the flash player or adding a rule to your perimeter devices to block swf files until there is an official patch. Also NoScript is your best friend.
