The boys in the IT department of my father's office sent him the following fix...

The virus reported to us yesterday was a hoax.* What the virus alert
actually did was to get you to delete a necessary operating file from your
C-Drive.* The file needs to be restored.

To do so:

1.* Click START - RUN, type SFC and hit ENTER

2.* In the "Specify the system file you would like to restore" field, type
C:WINDOWSCOMMANDSULFNBK.EXE and hit ENTER

3.* In the RESTORE FROM field, type, C:WINDOWSOPTIONSCABS

4.* Click OK and continue with the restore function

Hope this helps.
