This threat is considered to be a Low-Profiled risk due to media attention at: http://www.theregister.co.uk/content/56/34299.html
This W32/Mimail@MM variant seems to be buggy. Testing shows the virus doesn't always mail itself along with the email message, and may not send itself to harvested addresses.
The worm constructs email messages using its own SMTP engine. As with previous variants, the mailing routine queries the mail server for the domain related to the target (harvested) address. This is determined via an MX lookup on the target domain. Messages are then sent through that SMTP server.
This worm is received in an email message as follows:

Mail Propagation
The worm emails itself to addresses found on the infected computer. Target email addresses are harvested from files on the victim's machine. The worm ignores address extraction from files that contain the following extensions:
- avi
- bmp
- cab
- com
- dll
- exe
- gif
- jpg
- mp3
- mpg
- ocx
- psd
- rar
- tif
- vxd
- wav
- zip
Target folders are determined by querying the following Registry key:
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
Explorer\Shell Folders
Denial of Service Payload
The worm attempts to cause a denial of service on the following domains, via ICMP and HTTP traffic.
- www.authorizenet.com
- disney.go.com
- www.spamcop.net
- www.carderplanet.net
- www.cardcops.com
- www.register.com
- www.spews.org
- www.spamhaus.org
Symptoms
The following registry key is added to run the virus at startup:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
Run "France" = %WinDir%\svchost.exe
The worm creates the following files:
- %WinDir%\x8wui12s.tmp (compressed copy of the worm)
- %WinDir%\xu298da.tmp (harvested email addresses)
- %WinDir%\svchost.exe (copy of the worm)
- %WinDir%\xu39reu.tmp (copy of the worm)
Note: %WinDir% is a variable for the Windows directory name. The worm does not use this exact name. It simply uses the system %WinDir% directory.
The worm checks for an active Internet connection by pinging www.register.comMethod of Infection
This virus spreads via email. Manually running the attachment infects the local machine.

All Information
Overview -
This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.
