The worm arrives as the attachment Wife.scr. When the attachment is executed, it displays the following graphic:

It then copies itself to \%System%\Ox&Wife.scr.

NOTE: %System% is a variable. The worm locates the \Windows\System folder (by default this is C:\Windows\System or C:\Winnt\System32) and copies itself to that location.

It also adds value

OX C:\WINDOWS\SYSTEM\ox&Wife.scr

to the registry key

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

The worm uses Microsoft Outlook to distribute itself to all addresses in the Outlook address book. It also sends itself to all
contacts in MSN Messenger contact list. The email message has the following characteristics:

Subject: ox <--> sharon
Message:
Hi All,

ox <===> sharon
it's funny :-)
