Summary



This a Word macro virus which works only under German versions of Microsoft Word.

Clock disables the Word Tools/Macro menu (in German, Extras/Makro) and macro Organizer in order to hide itself better.

Clock replicates to documents whenever they are opened or closed through Word menus.

As a side effect, all macros from documents that get infected get copied to the NORMAL.DOT file.

Clock activates by sometimes displaying a dialog box with current date and time and sometimes swapping the menu functions for opening and saving files with each other.
