Hmmmm... wonder if this little bugger can infect Kubuntu? No it can't... another good moment to leave the clutches of Redmond I think ;-)

Yes, can you please mention "this affects Windows users" or something. It's not an issue for Mac or Linux or other systems.

I had just seen a study done where a web site was setup with a link named "download virus here" I wish I could find the post but was sad to see how many people actualy clicked the link. Of course, there was no real virus used in the study.

Why would a pif file infect non-windows machines?

that most people would know what a .pif file is? Its not as if its a file format that people come across frequently...

Cross network worms were one of the subjects of one presentation that I did with some friends during last Blackhat Europe. I would say that's just the first evolution. If they follow the points discussed during the presentation more things are coming. :-)
