System Error message after software download

[lavagirl669]

A friend has tried to download Blackberry Desktop Manager Software and after downloading and trying to open the Blackberry software, he gets this error message:

C:\Windows\system32\autoexec.nt. The system file is not suitable for running MS-DOS and Microsoft Windows application. Choose 'Close' to terminate the application

Any ideas on what's going on and what he can try to do?

he's already tried an uninstall of the BB DM software, also tried installing another version but still getting the system error msg.
Running Windows XP.

Thanks in advance!

"From several sources:

Autoexec.NT Problems Growing?
Fred, For the past few weeks on our forum we've been getting complaints
about XP throwing off the following message when a user tries to run a 16
bit program:

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.

It turns out that there is some malware going around that's deleting the
autoexec.nt file from the \windows\system32 folder. The fix, for now, is to
copy the backup autoexec.nt from \windows\repair to \windows\system32 and
then to run av and spyware checks with Spybot, AdAware and whatever AV
program the user has (all with the latest definitions, of course). I'm not
sure if the specific malware has been identified yet, but the above process
does seem to solve the problem. Hope your readers can benefit from this. "
