Type:: Worm

This is a typical VBS worm that uses Microsoft Outlook MAPI to mail itself out to all contacts in the email address book. One notable difference though lies in how this worm reacts to different mailer programs installed on the computer.

NOTE: The first sample of this worm the Symantec AntiVirus Research Center (SARC) received contained a bug that prevented it from replicating on any computer.
