Claim: The Windows file SULFNBK.EXE should be deleted because it masks a dormant virus.
Example: [Collected on the Internet, 2001]
A VIRUS could be in your computer files now, dormant but will become active on June 1. Try not to USE your Computer on Go to the "START" button. If it finds it, highlight it. Do not double click or file will automatically open. The bad part is: You need to contact everyone you have sent ANY DO NOT RELY ON YOUR ANTI-VIRUS SOFTWARE. McAFEE and NORTON CANNOT DETECT IT BECAUSE IT DOES NOT BECOME A VIRUS UNTIL JUNE 1ST. WHATEVER YOU DO, DO NOT OPEN THE FILE!!! |
Origins: Whether the SULFNBK.EXE message was deliberately intended as a prank for gullible computer users or an honest warning based on a misunderstanding, the instructions listed above should NOT be acted upon. The file SULFNBK.EXE is a standard component of the
problem.)
SULFNBK.EXE is one of the files that the W32/Magistr.a@MM virus used as a means of transmission — infected copies were attached to mail messages which copied them to the recipients' PCs. (The real SULFNBK.EXE file should be found in the C:WindowsCommand folder.) However, the mere presence of this file does not mean that a system is infected.
You should not delete SULFNBK.EXE unless a virus-check program has scanned the file and told you it is infected. (The lack of SULFNBK.EXE won't generally cause a PC to stop working, but users who have removed it from their PCs should make the effort to restore it to avoid potential problems.) If you have already mistakenly deleted this file, you can find instructions for restoring it at Microsoft's web site or on the Symantec page linked below.
