16 bit MS DOS Subsystem
The system is not suitable for running MS-DOS and Microsoft Windows
applications. Choose ‘Close’ to terminate the application.
I did not have this before. Please advise me how to fix this

The 16 bit subsystem is what allows some older MS-DOS software to run in
today’s Windows NT and XP. It sets up a simulated MS-DOS environment, and many
old applications can run fairly well. (This not to be confused with the Command
Shell, which is a true 32 bit Windows application.)
But in this case it looks like some old 16 bit MS-DOS application is
attempting to start when you log in. In fact, it’s possible that the 16 bit
debugging program debug.exe is being started.
If you had just installed some new software, I might suspect that as the
cause. Especially if it was a new install of some old software package. However
my assumption is that this isn’t the case.
So I would do three things:
I actually suspect spyware, but I’ve not seen one that starts a 16bit
program before. In any case, since it’s trying to start when you start up
Windows, the last approach should allow you to disable it if the spyware and
virus scan don’t stop it.
