Yeah! Another variant. None of my virusscanners detected the sucker...
But fortunately I have a build in virusdetector in my head
I submitted it to McAfee and they told me it was a new detection.
You'll need the 4381 DAT which will be released on the 28th.

It arrived by email but the body text was unreadable. It looks like it uses a different characterset but the mime-type was set to us-ascii. Needless to say the text is unreadable.
The attachment is a zipfile which in turn contains another zipfile. This zipfile contains a readme.bat but is actually an executable.

I only found some info on the McAfee site. I guess the others will follow shortly.
