Autoexec.nt disappears from system 32 file folder

My computer uses XP. Whenever I try to open a 16-bit program ( when I have restarted my computer), I get the following message about 'autoexec.nt' in the System32 directory:

       The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application.

Of course, chossing 'close' or 'ignore' brings the same conclusion; the program does not open.

I have scanned my computer for viruses using McAfee; also did Stinger online as well as the housecall at Trendmicro.com.

Nothing was found.

If I copy the file 'autoexec.nt' from 'repair' directory into system32 directory, then the program opens. However, whenever I restart my computer, the file is no longer in system32 directory and the program will not open, until I copy from the repair driectoryagain.

I cannot find my XP CD to expand certain files, as a previous solution was given. Is there anything that I can do, to keep from having to copy this file everytime I reopen my computer?

Thanks for any help you can give me.

Copy the file over from the repair directory like you have done numerous times already, but this time make the file read only. (Right click - Properties Check the Read only box)

Worth a try?

I realise this is just a workaround, and if there is malicious software on there, it needs getting rid of. (Well, you know that already.)
