ntfs.sys file corrupt-virus related?

OK, I swear I didn't do anything to this computer except
restart it. Upon restarting it, the computer gives me
the following error message:

Windows could not start because the following file is
missing or corrupt:
system32\drivers\ntfs.sys

You can attempt to repair this file by starting Windows
Setup using the original setup cd-rom. Select 'r' at the
first screen to start repair.

OK, I don't get an R at the first screen. Infact, it
attempts to load some files and then gives me the error
message of : File setupdd.sys could not be loaded. The
error code is 4. Setup cannot continue.

OK, my floppy drive isn't working properly, the light
stays on continuously, so it has been unhooked (it was
like this prior to any problems, and this is the first
problem I have had with the computer except for the
Wormblaster Virus). My neighbor coppied the ntfs.sys
file to a CD, however, we cannot start the computer in
safe mode with command prompt because it keeps giving us
the same message and keeps rebooting. Husband is in the
military and out to sea, would like to get this resolved
prior to him coming home...could it be a virus, or what
is going on here and HOW CAN I FIX IT???????
