16 Bit windows subsystem error

[Guest]

I use windows XP Proffesional Edition. I get an error message now when I try
to run certain software. I have ran this software for years using this
operating system but all of the sudden it won't let me. Could someone please
tell me what it means or how to fix it. Message is as follows:

16 Bit Windows Subsystem
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.

Help

Seems to be an epidemic lately....

This can be caused by a trojan.

Get rid of the trojan.

Update your antivirus software and run a full system scan.

Copy the autoexec.nt file from C:\Windows\Repair to C:\Windows\System32.
And set Attributes for autoexec.nt to Read-only.

Read-only
[[Specifies whether this file is read-only, which means that it cannot be
changed or accidentally deleted.]]

1. Right click the file.
2. Properties.
3. Select: Read-only.
4. Click: Apply.
5. Click: OK.
