I was actually getting some pretty clever ones from <someadmintypename> @greeblesnort.com (which I own) stating my email had been used for something bad and please use the enclosed instructions (looks like a zip file)to correct it. Obviously, I wasn't sending them to myself, so it was not quite as clever, but the .zip was actually a .zip<many spaces>.pif

I received an email with subject "My Best Photo" and an attached file named Photo.zip. The email text read as follows:

Hi,
I want to share my photo with you.
Wishing you all the best.

The interesting part is what was in the Photo.zip file:

Archive:  Photo.zip
  inflating: Photo/Photo.bmp
 extracting: Photo/View-Photo.bat

The file View-Photo.bat consisted of one line:

Photo.bmp

The file Photo.bmp was some sort of executable binary file. When I look at strings Photo.bmp I see "MS-Outlook" in there, so I think this virus uses MS Outlook.

Anyway, I guess this means that Windows will execute a file without .exe, .com or .bat extension if it is called from within a batch file. People who receive this thing will try to open the Photo.bmp, but that will fail because it isn't a proper BMP file, so they will then click the View-Photo.bat file and they'll be screwed.
