A recent variant of this trojan, upon execution, quits and displays two error message boxes which states:
"Runtime error 216 at [memory location]".
--Update on August 20, 2008 ---
The risk assessment of this threat has been updated to Low-Profiled due to media attention at:
http://www.itbusinessedge.com/blogs/hdw/?p=2897
and http://newsblaze.com/story/2008081510190500001.wi/topstory.html
The trojan author uses a fake BBC news about President of Georgia to spread the malware. The spammed emails contain a link, which would cause downloading an executable file, often called name.avi.exe.
Upon the execution, the desktop background of the compromised machine is changed:
The desktop and screen saver tabs in "Display Properties" window disappear to disable the victim to manually change them.
A window is pop up to ask the victim to agree to install Antivirus XP 2008. There is cancel or close button in this window.
When the victim clicks the agree and install button, the Antivirus XP 2008 scan window is displayed.
The malware drops the following files:

This is an automatically generated description for Trojan Downloaders.
Downloaders are designed to pull files from a remote website and execute the files that have been downloaded.
As it is trivial for the malware author to modify the Downloader to refer to a different website or web address, McAfee write detection routines for Downloaders which as a general rule do not include these strings in the detection routines.
This allows McAfee to write more generic detections for these threats and to proactively protect customers against future minor variants.
Therefore it is not possible to guarantee which website and/or port is being communicated with.
Also, as the website being communicated is normally controlled by the malware author, any files being downloaded can be remotely modified and the behaviour of these new binaries altered - possibly with every user infection.
Symptoms
Many of these Downloaders install other malware including viruses as well as other Trojans.
Additionally many of them are used to remotely install Adware packages onto the affected host machine for the purposes of gaining referral revenue from the Adware software vendor.
Please note: If Adware is installed via a Downloader it may install it "cleanly" with the relevant uninstaller included for the user to terminate this Adware, although frequently this is not the case.
Method of Infection
N/A. Downloaders are not viruses, and as such do not themselves contain any method to replicate. However they may themselves be downloaded by other viruses and/or Trojans to be installed on the user's system.
Many of these additionally are mass spammed by the author to entice people into double-clicking on them.
Alternatively they may be installed by visiting a malicious web page (either by clicking on a link, or by the website hosting a scripted exploit which installs the Downloader onto the user's system with no user interaction.
Removal
All Users:
Use current engine and DAT files for detection and removal.
Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).
