In the last week I’ve seen this hit in the wild several time and at several locations. At one location this virus infecting over 200 computers. The email arrives as follows
From: United Parcel Service [user@not_ups.com]
Subject: UPS Paket N473133142

There is a variant of this from FedEx and from United States Customs. They have even posted this response to the email at http://www.customs.gov/xp/cgov/newsroom/alerts/email_virus.xml

The ones I have seen install a Trojan that then begins sending out Spam. They have all been part of the Cutwail Botnet. This botnet includes around 150,000 computers, sending over 16 Billion Spam emails a day.
None of the Virus scanners I had could clean this, and all the information is about older version of the cutwail virus. I always recommend if you get infected with any type of trojan/virus like this to just do a reinstall, never ever trust an infected machine again. I had this cleaned or so I thought on one computer until I rebooted and it was found again by Trend. Trend could not clean or quarantine this virus.
This version created a file in c:\windows\system32\drivers\tcpsr.sys and c:\windows\system32\drivers\Win32x.sys, there was also several registry keys created I did not copy these down before the reinstall.
Side note:
Let me just point this out also. None of the systems that where infected are protected by the Spam and Virus protection provided by my employer. I have checked the logs on all of our spam/virus gateway systems and this virus has been stopped all along. If you own your own domain, and want Spam and Virus protection, you can contact me for pricing.
