I was trying to figure out what the virus is that is being distributed by this latest rash of e-mails but it took a little while to find an article mentioning both UPS and the name of the trojan/virus/botnet.

The name of the trojan is Pushdo  (Sophos) and Pandex (Symantec).

Here are links with more information:
