One more Netsky variant found, although it's a bit unclear if this was actually distributed before Netsky.J (which we found earlier today). This new 22016 byte long variant seems to be spreading a bit more than some of the other recent variants.

Typical message sent by this variant could look like this:

   From: spoofed-address
To: random-address
    Subject: Re: Your music
 
             See the attached file for details.
