Can't run dos programs! PLEASE HELP! Need to update drivers!

[Guest]

When I try to run a DOS Program I get the following error, please assist!

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 have two options at this point... 'Close' and 'Ignore'... 'Ignore' does
nothing and 'Close'... well closes it.

A good practice to adopt when using newsgroups is to read through several
day's worth (at least) of posts to see if someone else has already asked the
question you want to ask and received an answer. In fact, your question is
asked a dozen times or more each week in these newsgroups.

Seems to be an epidemic lately....

This can be caused by a trojan.

Get rid of the trojan.

Update your anti virus 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.
