16-bit subsystem

[Guest]

How come, when I try to run an older program (maybe 4 or 5 years) it comes up
saying that it may not be safe to run a 16-bit subystem. It then gives me an
option to ignore the warning or abort the operation, and if I click, ignore,
it just closes the box, and doesnt do anything as if I were to click abort.

Seems to be an epidemic lately....

This can be caused by a trojan.

Get rid of the trojan.

Update your antivirus 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.
