Cuydoc is a worm that only runs under Spanish versions of Windows, which deletes all the Word documents (files with a DOC extension) from the directory Mis documentos.
In Spanish versions of Windows Me/98/95, Cuydoc prevents the user from running the REGEDIT.EXE program, which allows the user to edit the entries in the Windows Registry, and the MSCONFIG.EXE program, which allows the user to configure which programs will be loaded when Windows starts.
Cuydoc spreads through the means normally used by viruses. Similarly, in computers running the Spanish version of Windows Me/98/95, it can also spread across floppy disk drives by automatically coying itself to them.
Cuydoc is difficult to recognize, as it does not display any warnings or messages that indicate that it has infected a computer.
