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.
Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.
