I fell for the SULFNBK.EXE Warning, how do I fix this?
Symantec
has a good write up on this hoax. You can visit for more info at:

Below is their quickfix summary:
Windows Me
If you are using Windows Me, you can restore the file using the System
Configuration Utility.
1. Click Start and then click Run.
2. Type msconfig and then press Enter.
3. Click Extract Files. The "Extract one file from installation
disk" dialog box appears.
4. In the "Specify the system file you would like to restore" box,
type the following, and then click Start:
c:\windows\command\sulfnbk.exe
NOTE: If you installed Windows to a different location, make the
appropriate substitution.
The Extract File dialog box appears.
5. Next to the "Restore from" box, click Browse, and browse to the
location of the Windows installation files. If they were copied to the hard
drive, this is, by default, C:\Windows\Options\Install. You can also insert
the Windows installation CD in the CD-ROM drive and browse to that location.
6. Click OK and follow the prompts.
Windows 98
If you are using Windows Me, you can restore the file using the System File
Checker.
1. Click Start and then click Run.
2. Type sfc and then press Enter.
3. Click "Extract one file from installation disk."
4. In the "Specify the system file you would like to restore" box,
type the following, and then click Start:
c:\windows\command\sulfnbk.exe
NOTE: If you installed Windows to a different location, make the
appropriate substitution.
The Extract File dialog box appears.
5. Next to the "Restore from" box click Browse, and browse to the
location of the Windows installation files. If they were copied to the hard
drive, this is, by default, C:\Windows\Options\Cabs. You can also insert the
Windows installation CD in the CD-ROM drive and browse to that location.
6. Click OK and follow the prompts.
Windows 95 (or alternative method for Windows 98/Me)
If you are using Windows 95, you need to use the extract command. This can also
be used on Windows 98/Me.
1. Click Start, point to Find or Search, and then click Files or Folders.
2. Make sure that "Look in" is set to (C:) and that Include
subfolders is checked.
3. In the "Named" or "Search for..." box, type:
precopy1
4. Click Find Now or Search Now. If it does not exist on the hard drive, then
insert the Windows installation CD and repeat the search on that drive.
5. When you find the file, write down the location of Precopy1, for example,
C:\Windows\Options\Cabs. This is your Source Path.
6. The general form of the Extract command is:
extract <Source Path>\precopy1.cab sulfnbk.exe /L c:\windows\command
So if the source path is C:\Windows\Options\Cabs, then the Extract
command becomes:
extract c:\windows\options\cabs\precopy1.cab sulfnbk.exe /L c:\windows\command
NOTE: If you installed Windows to a different location, make the
appropriate substitution.
7. Click Start and then click Run.
8. Type the following, making the appropriate substitutions as previously
noted
extract <Source Path>\precopy1.cab sulfnbk.exe /L c:\windows\command
9. Click OK.
