Edit it with NotePad. It should contain - apart from many comment lines
starting REM - just

REM Install CD ROM extensions
lh %SystemRoot%\system32\mscdexnt.exe

REM Install network redirector (load before dosx.exe)
lh %SystemRoot%\system32\redir

REM Install DPMI support
lh %SystemRoot%\system32\dosx

And possible SET or PATH lines:

Remove anything else by turning it into a comment, adding REM and a
space as shown in the above. And please note what they were and report
back - this is happening a lot and I would like to find out *what* has
got added.

Copy the autoexec.nt from c:\windows\repair into c:\windows\system32 and it
will be fixed. This was caused by a piece of malware. You may want to
have someone take a look at your HijackThis log to make sure there is
nothing there.

Create a directory on your hardrive to save HijackThis.exe. A directory
like c:\hijackthis. If you do not do this, you will not be able to use the
backup/restore features.

Download HijackThis from:

http://www.bleepingcomputer.com/files/hijackthis.php

Save this file into the directory you made previously and then run the
program named hijackthis.exe. When the program opens click on the Config
button, then click on the Misc Tools button, and click on the Check for
update online button. When it completes checking/applying updates press the
back button.

Now click on the Scan button and when it is finished click on the Save Log
button. A Notepad window will open with the contents of this log. Click on
Edit then click on Select all. Then click on Edit and then Click on Copy.

Register an account at http://www.bleepingcomputer.com and post this created
log into the Hijackthis Logs forum at that site. To do this, once you are
registered, create a new post, right click in message area and select paste
to paste the log into the post.

An expert will reply to you after reading this post. DO NOT fix any entries
unless you are absolutely sure you know what you are doing as you may cause
more damage to the system
