A hoax warning: Infecting SULFNBK.EXE file
Any merit to this email??
"Everyone - please read & forward to anyone you have emailed in the last month
I was notified by a friend that she inadvertantly passed on a virus to my
computer over the past month. I just found out about it and supposedly it is
passed on when you send emails to others. I did find it on my computer and
deleted it. The virus is supposedly programmed to activate after being on
your C drive for awhile. Because of the delay in
activation it does not get picked up by anti-virus programs. No one knows how
long the virus has been on the system. When it does become active it will
erase all files and folders on your hard drive. It is spread when you send
In order to find this virus, follow the instructions below:
Click on "start"
choose "files and folders"
select "find" Select "C drive"
Name of file to search for SULFNBK.EXE
If you find this file, DO NOT OPEN IT! Select by right clicking on your
mouse and DELETE it. Then close the window and empty your RECYCLE BIN.
Please contact anyone you may have sent emails to in the last month.
Sorry about this."

I have found this security warning from Symantec website and have inserted for you And like you mentioned, this hoax does not become a virus until the set time.
This hoax email was first reported in Brazil The original email is in Portuguese and it is followed by several other versions.
This particular email message is a hoax The file that is mentioned in the hoax, however, Sulfnbk.exe, is a Microsoft Windows utility that is used to restore long file names, and like any .exe file, it can be infected by a virus that targets .exe files.
The virus/worm [email protected] can arrive as an attachment named Sulfnbk.exe The Sulfnbk.exe file used by Windows is located in the C:\Windows\Command folder If the file is located in any other folder, or arrives as an attachment to an email message, then it is possible that the file is infected In this case, if a scan with the latest virus definitions and with NAV (Norton Anti Virus) set to scan all files DOES NOT detect the file as being infected, quarantine and submit the file to Symantec Security Response for analysis by following the instructions in the document How to submit a file to SSR (formerly, SARC) using Scan and Deliver.
If you have deleted the Sulfnbk.exe file from the C:\Windows\Command folder and want to know how to restore the file, see the following section How to restore the Sulfnbk.exe file.
How to restore the Sulfnbk.exe file:
If you have deleted this file, restoration is optional Sulfnbk.exe is a Microsoft Windows utility that is used to restore long file names It is not needed for normal system operation If you want to restore it, there is more than one way to do this See the information that follows.
