Discovered on December 14, 1999 in Italy. This worm will email itself out when receiving email via Microsoft Outlook or Netscape Navigator. When activated the worm will display an error dialog and modify the registry so the worm is reloaded each time the computer is restarted.
The error message box will appear as:
The dynamic link library giface.dll could not be found in specified path
D:\SAMPLES;C:\WINDOWS\SYSTEM;C:\WINDOWS;C:\
WINDOWS\COMMAND

When received by email (and if you do not have an HTML capable email client), the message body will be:
he, your lame client cant read HTML, haha.
click attachment to see some stunningly HOT stuff

Otherwise, the text will read:
