Repairing Damage Caused By SULFNBK.EXE Virus Hoax



There is a virus hoax that can actually cause minor harm to one's computer if the instructions for ridding your computer of the hoax 'virus' are followed. The hoax is a message saying that "c:windowscommandsulfnbk.exe" is infected with a virus and that users should delete it asap, and to pass this message on.

If you recieve this message, do not delete the file as instructed. It is not a virus, but rather a Windows system utility used to restore long file names. Like any .exe file it can be infected with a virus, but it is not a virus in and of itself.

Anyone who deleted the file will need their Windows installation CD to restore it. Select one of the following two methods to extract the sulfnbk.exe file if you deleted it:

NOTE: If the location "D:win98" in the instructions below does not work for you, other locations to try are c:win98 and c:windowsoptionscabs

Method 1 (windows 98 only):
  1. Insert your Windows 98 CD.
  2. Click on the Start menu and Select Run.
  3. Type sfc and click OK.
  4. Click the option for "Extract one file from installation disk."
  5. Type sulfnbk.exe and then click Start.
  6. In the "Restore From:" box, type D:win98 (replace 'D:' with your CDROM driver letter if it is not the D drive).
  7. In the "Save File In:" box, type c:windowscommand and click OK.
  8. You should get a confirmation that the file was extracted successfully.
  9. Close the System File Checker window.

Method 2 (***Users of Windows ME will need to use this method):
  1. Insert your Windows 98 CD or Windows ME CD.
  2. Click on the Start menu, then Programs, (then Accessories for Windows ME), then MS-DOS Prompt.
  3. Type D:win98 (replace 'D:' with your CDROM driver letter if it is not the D drive).
    (NOTE: Windows ME users will need to type d:win9x)
  4. Type extract /L c:windowscommand precopy1.cab sulfnbk.exe
  5. It should extract the file, the put you back at the "D:win98" (or D:win9x for Windows ME) prompt.
  6. Close the MS-DOS Prompt window.
NOTE: If you do not already have virus scanning software installed on your computer, you can download Macintosh or PC virus software here: http://osusls.osu.edu/.
