VBS.Oap@mm is a worm that spreads by replying to all messages in the Microsoft Outlook inbox. The message that the worm sends is the same message that is in the inbox, but with the worm attached at the bottom.

VBS.Oap@mm is, like many other worms, written in the Visual Basic Scripting (VBS) language. Due to the fact that many worms are written in the Visual Basic Scripting language, SARC offers a tool to disable the Windows Scripting Host.
