Worm.Win32.Nople, simply known as Nople, is a Microsoft Windows mass-mail worm.


Nople is a Windows PE EXE file about 51Kb of length, written in Microsoft Visual C. The worm copies itself to C:\WinNT directory with the "noplease_flash_movie.exe" name, then spreads with the same name over local network and copies itself to shared network drives. The worm is able to spread over WinNT machines only. It also starts its copies on remote machines as services, in case there is permission for that.

The worm manifests itself with a messi and colorful video effect and displays the text in Spanish:

Es hora de formatear tu disco

Which translates to:

It's time to format your disk
