There seem to be a load of files cropping up with the format:
!!!filename_mp3.asf
and
XX-setup-XXfilename.exe/.rar/.zip
which bear no resemblence in size to the file they are obviously trying to look like. This looks remarkably like the Benjamin worm that cropped up on Kazaa. I downloaded one of the files but Norton couldn't find anything in it.
Have I unwillingly infected myself?

Comments appreciated.

David
