16 bit subsystem?

I need help!!! I have been battling all week with trojans, I think I have everything fixed up but now when I try to install programs , CD-Rom, I get a message saying: 16 bit Windows subsystem
C/windows/system32/autoexec.NT The system file is not suitable for running MS DOS and Microsoft Windows Applications
Even when I choose ignore my nothing happens. I am wondering if I have changed a setting or something. Does anyone know? I am using XP.

Hello again! I am getting very frustrated now!!!! Turns out I had about blank and some other trojans. I think that is all fixed up, but is that why my autoexec.NT file was missing? I copied and pasted it from Windows repair and now when I try to install programs from my CD Rom I am getting a message that D:\setup.exe is missing. I had to use task manager to close the error boxes( and the full white screen that said loading, which I have never seen before!) and in task manager ntvdm.exe and wowexec.exe were running????????help, I really don't know what I am doing!

This installaton program will reinstall the missing or corrupt Windows XP system files command.com, autoexec.nt and config.nt. The absence or corruption of one or more of these files causes a "16 Bit Subsystem" error.
