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

1. Right click the file.
