I have a forum showing up the same Virus/Worm.
hxxp://www.syaoregon.us/forum
The url that Avast! shows is:
http://www.syaoregon.us/forum/\unp263177177
VPS version: 080725-1, 07/25/2008
It's an outdated SMF forum. All links to it show up infected. This is just too weird.
All other sites & SMF forums work fine for me.
