Unable to run some older files all of a sudden

[S_Nyaya]

Hi,

Some archived files - generally animations and such - that used to run in
MS-DOS windows, now no longer do so, on one WinXP Pro machine. The user gets
the following 16-bit Windows Subsystem error message:

"C:\windows\system32\autoexec.net. The system file is not suitable for
running MS-DOS and Microsoft Windows applications. Chose "close" to
terminate the application"

The warning window closes without any further action whether the "close" or
"ignore" buttons are clicked.

I know for certain that this was not the problem earlier and that no
software instals or un-instals and system changes were made on that
particular machine. The only change is that each and every Microsoft updates
are automatically downloaded and selected for install.

I am somewhat at a loss to figure out what to look at. Selecting any
non-running file and selecting the appropriate compatibility mode does not
help.

Any pointers would be most appreciated.

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

Also can be caused by a Trojan installing a file windupdater.exe and
creating registry entries for that file.

AVAST (free antivirus software) can be the cause if SP2 is installed:

You can put back the standard version of autoexec.nt by copying a backup
copy held in windows\repair to windows\system32.
