Macro.Word.Showoff

Description Macro.Word.Showoff

text (c) Michal A. Egler
This virus contains the following encrypted macros: Hayo, AutoOpen, Nomercy2, Organizer, ToolsMacro, FileTemplates.
On the 13th day of any month the virus creates the file C:WINDOWSSYSTEMNOMERCY.DLL. This file contains a debug script with the NoMercy.575 DOS parasitic virus dump code. By using this script the virus creates the virus dropper NOMERCY2.COM.
Next the virus deletes files:
C:*.BAT
C:*.SYS
C:WINDOWS*.GRP
C:WINDOWS*.DRV
C:WINDOWS*.DLL
C:WINDOWSSYSTEM*.DRV
C:WINDOWSSYSTEM*.DLL

It also inserts the following commands into the AUTOEXEC.BAT file to execute the virus dropper:
@echo off
nomercy2.com

After restarting the computer the virus code stays resident and infects each executed COM and EXE file.
The virus displays a UserDialog containing the text:
No Mercy II [Hell on WinWord], The Madness Continuesall..

Sometimes the virus displays a UserDialog with the text:

Macro.Word.Shuffle

Description Macro.Word.Shuffle

This is a stealth Word macro virus. It contains one macro in documents (AutoOpen) and four macros in NORMAL.DOT (XXXXX, FileSaveAs, ToolsMacro, FileTemplates).
The virus infects the global macros area (NORMAL.DOT) on opening an infected document (AutoOpen) and writes itself to documents that are saved with new name (FileSaveAs). The virus infects the documents in usual way, while infecting the NORMAL.DOT the virus deletes all macros in there, minimizes the Word window, and copies its macros string-by-string to the global macros area.
