When the attached file is executed, the worm will mail itself to the each recipient in every address book. After mass mailing have been done, this variant adds the following key to the registry:
    HKEY_CURRENT_USER\software\mailed
This variant also replicates using mIRC and Pirch IRC clients.

There is also a version that is not encrypted. However, due a bug it does not replicate.
