VBS.JongBoy@mm is a worm that can spread using the popular chat program mIRC and through Microsoft Outlook. VBS.JongBoy@mm deletes the Regedit.exe file and attempts to overwrite several other system files.

VBS.JongBoy@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.
