W32.Gibe@mm is a worm that uses Microsoft Outlook and its own SMTP engine to spread. This worm arrives in an email message--which is disguised as a Microsoft Internet Security Update--as the attachment Q216309.exe. The worm also attempts to copy itself to all locally mapped remote drives.



It has been discovered that this worm may distribute corrupted copies of itself which are non-functional. Virus definitions dated March 11, 2002 or later will detect these as W32.Gibe.dam. Files detected as such must be deleted.
