My apologies to all I sent the email on the "sulfnbk.exe" virus alert. Apparently, this is a hoax and had I done my homework prior to reacting by sending out these emails I would not be having to send out this info. All deleting the file does is make it tough to restore long file names (read all about it below). What I have included in this email is info on the "virus" and it tells you how to restore it the file if you have deleted it.

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.
