I just got an email from somebody I know that has about 100 other email addresses listed in the "to" line.  It told me that their computer has a virus that was sent out to everyone in the address book.  The virus is listed on the C drive as "sulfnbk.exe" and it does appear on my hardrive.  The email gives instructions for how to delete the "virus" before it destroys my computer.  I haven't received email from this individual in over a year, and I never opened any attached files.  I'm thinking that this file has always been on my computer and this email is in fact a virus that is telling me to delete something important.

Should I delete sulfnbk.exe?  

In many years of working on the computer, I'm still waiting to see an email that talked about a virus that wasn't a hoax.  This one proved to be no different.  Going to Norton.com and doing a search for sulfnbk.exe brought up this:

That's what I figured.  Thanks.

We got that one early this year. Unknowingly, I deleted the file. How do I put it back? Tried to copy off computer here at work to a disc, but cant seem to get it to the window operating system.

These internet jerks would rather write malicious programs than play with womenZ?

Losers...
