I'm running Windows 2000 and get the following error message on startup: 16-bit MS-DOS Subsystem path to the program that you are trying to start or install C:\WINNT\System32\Autoexec.nt The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application. The computer then tries to reinstall Microsoft Office from CD. I've found and deleted Msblast and Mslaugh viruses. Would uninstalling MsOffice from the Add/Delete Programs in Control Panel cure it? Please help!
