Installing programs

[Guest]

I am trying to install a program on my machine. I have Windows XP Home
Edition, with service pack 2. Whenever I try to run the setup on the CD, it
says...

C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running
MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the
application.

I did have a virus, but I now have good anti-virus protection. Did I
accidently erase a file?

Hi

Error message when you install or start an MS-DOS or 16-bit
Windows-based program

You can put back the standard version of autoexec.nt/config.nt by
copying a backup copy held in %windir%\repair\ to %windir%\system32\
(%windir% is typically C:\Windows) instead of using the procedure in
the KB article above.


Could be caused a trojan or something similar, e.g.
TrojanDownloader.Win32.Dia.a, more about this here:

Also, AVAST (antivirus software) can be the cause if you
have WinXP SP2 installed:
