There's a new Windows email virus, capable of destroying files and damaging
systems. This time, it's
purely memetic. The SULFNBK.EXE virus consists
of a warning email, warning of a dangerous and undetectable virus, hidden in a
file named SULFNBK.EXE, and instructing the recipient to locate and delete this
file. SULFNBK.EXE, however, is a Windows system component to do with long
filenames, and deleting it does the damage.
