Was macht die Datei SULFNBK.EXE

[Tarjan]

Hat einer eine Ahnung was diese Datei macht?

Habe gerade von einen Freund folgende Mail bekommen:

I HAVE JUST FOUND THIS IN MY SYSTEM AND CHANCES ARE YOU HAVE IT TOO,
SINCE
YOU ARE ALL IN MY ADDRESS BOOK. IT LIES DORMANT FOR 14 DAYS, AND THEN
KILLS YOUR HARD
DRIVE. HERE'S HOW TO STOP IT. IF YOU'VE GOT IT, SEND THIS TO EVERYONE
IN YOUR ADDRESS
BOOK.

REMOVE IT BY THE FOLLOWING STEPS:

1. GO TO "START", THEN TO "FIND" OR "SEARCH" (DEPENDING ON YOUR
COMPUTER).
2. IN THE "SEARCH FOR FILES OR FOLDER", TYPE "SULFNBK.EXE" -- THIS IS
THE VIRUS.
3. IN THE "LOOK IN", MAKE SURE YOU'RE SEARCHING DRIVE C.
4. HIT "SEARCH" BUTTON (OR FIND).
5. IF THIS FILE SHOWS UP (IT'S AN UGLY BLACKISH ICON THAT WILL HAVE THE
NAME YOU TYPED
ABOVE), DO NOT OPEN IT!!!
6. RIGHT CLICK ON THE FILE, GO DOWN TO DELETE AND LEFT CLICK.
7. IT WILL ASK IF YOU WANT TO SEND IT TO THE RECYCLE BIN, SAY YES.
8. GO TO YOUR DESKTOP (WHERE ALL YOUR ICONS ARE) AND DOUBLE CLICK ON THE
RECYCLE BIN.
9. RIGHT CLICK ON "SULFNBK.EXE" AND DELETE AGAIN -- OR EMPTY THE BIN. TO
DELETE ALL - CTRL
+ A (TOGETHER) AND THEN DELETE.


Ich halte das ganze für einen Riesenschwindel um eine Windows Dos Systemdatei zu löschen. Habe diese Datei bei mir unter \Windows\Command gefunden und bin mir sicher, dass ich Virenfrei bin.

Habe auch schon zurückgeschrieben, dass ich das für einen Schwindel halte. Würde aber trotzdem gerne wissen, für was diese Datei gut ist.
