the file may be missing

you should have a copy of autoexec.nt in your windows\repair folder


just *copy* it to the system32 folder

Seems to be an epidemic lately....

This can be caused by a trojan/virus/worm.

Get rid of the trojan/virus/worm.

Update your antivirus software and run a full system scan.

Update whatever anti-spyware applications that you have and run a full
system scan with each one.

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

Or %systemroot%\Repair to %systemroot%\System32

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.
