Norton Virus Hoax listings

For "sulfnbk.exe" virus hoax information:

A hoax about this file being infected with a virus is making the e-mail rounds again.  The hoax says to look for the sulfnbk.exe file and claims that, if you have it on your computer, its infected with a virus.  ALL Windows 98/98SE/ME computers have this file, its a regular Windows system file.  While its possible that yours is infected, it's probably fine.

"Is my file infected?"

1) If you have anti-virus software on your computer, update the virus definitions and then do a full system virus check.  If sulfnbk.exe or any other file is infected, this will tell you.  If your computer has no viruses, relax.  If the software DOES find a virus, follow the instructions in your anti-virus software to fix it.

- or -

Use the "find" or "search" utility (click "start", then "find" on Windows 98 or "search" on Windows ME) to find your sulfnbk.exe file.  Right-click on the file name to get a list of options, left-click on the option to scan for viruses (if you have this option, the wording may be different) and you can just scan this specific file.

2) If you do NOT have anti-virus software on your computer (a big mistake in today's on-line world) you can still check to see if you have a virus.  Click this link to go to Symantec Corporation's free virus detection program.  It takes a little while to load, since it has to install an application and then scan all your files, but it does a thorough and accurate job.  NOTE:  This software will detect a virus but not treat it.  After all, this company sells anti-virus software (they make Norton Anti-Virus, widely considered the best, BTW).

"How do I get the non-infected file back?"

If you followed the hoax instructions and deleted the file then emptied your Recycling Bin, you deleted a file that is not essential for Windows operation but that you should have on your computer.  To get the file back you'll need to download a new copy. 

a) Right-click on the link below, then left-click on the option "save target as".  That command will open a box called "save as" which shows you drives, folders and files on your computer. 

b) At the top of the box click the arrow by the words "save in" and then click the rectangle icon next to "(C:)" (that's your "C" drive)

c) Staying in that "save in" box, double-click on the manila folder icon called "Windows", then to the manila folder icon called "command". 

d) Once you've navigated to the "command" folder, just left-click the command "save" above the cancel command.  That's it.  The file's back and its fine.  It's not hard.
