This is an encrypted Word macro virus. It contains three macros: AutoOpen,
ToolsMacro, QuickSilver. It infects only documents and does not install
itself into the global macro area – on opening an infected document the
virus opens the list of recently used files and affects them.
The virus disables the Tools/Macro (ToolsMacro) menu (stealth), moreover it
replaces that menu if it has another name.
