 Sulfnbk hoax lever stadig
14-11-2001
 
Der er begyndt at komme mange henvendelser fra folk, der modtager den falske advarsel igen, om en virus kaldet sulfnbk.exe, som ødelægger computeren d.1-6-2001. Advarslen beder folk om at slette filen, hvis den skulle ligge på computeren. Filen ligger i c:/windows/command Filen hedder sulfnbk.exe og må IKKE slettes. Den bruges til at håndtere lange filnavne i Windows, og det anbefales ikke at slette den. Advarslen kommer som et kædebrev, som beder alle om at slette filen de har liggende på computeren, samt videresende mailen til alle som brugeren har sendt mails til den sidste måned. Vi gentager at filen ikke må slettes. Martin Rhodin Virus112 A/S //hvis du - som jeg - allerede har slettet den, så læs mere nedenfor

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 98, 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 /a <Source Path>\precopy1.cab sulfnbk.exe /L c:\windows\command

NOTE: Make sure that you include the /a switch, as shown. Depending on your version of Windows, the Sulfnbk,exe file can be in a .cab file other than Precopy1.cab. By using the /a switch, the Extract program will look first in the Precopy1.cab, and if the file is not found there, it will look in all subsequent .cab files until it is found, and can be extracted.

So if the source path is C:\Windows\Options\Cabs, then the Extract command becomes:

extract /a 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 /a <Source Path>\precopy1.cab sulfnbk.exe /L c:\windows\command

9. Click OK.
