Anyone who is not a slave to Microsoft, need not be concerned with this virus:

from http://vil.nai.com/vil/content/v_99367.htm

This worm makes use of Incorrect "MIME Header Can Cause IE to Execute E-mail 
Attachment" vulnerability in Microsoft Internet Explorer (ver 5.01 or 5.5 
without SP2)

This worm arrives in an Email message with a subject and body randomly 
composed from a rather long pool of strings that the virus carries inside 
itself (the virus can also add other strings):
