When an infected document is opened, the virus will change the title of the Word's window to:

    MiMiR is giving your computer new intelligence!  

Then the virus ovewrites the three recently used documents as well as every file with ".doc" extension in the "C:" drive with the active document.

Finally it attempts to use Outlook to send a message to the every person listed in the "Contacts" folder. The body of these messages contains the following text:

The active document is attached to the message as well.
