Correction: F-Prot merely finds the infected file on my hardrive.

Running it in DOS doesn't do anything at all. It is not necessary
to reboot.

Fortunately, nothing happens. I guess if it can't find WSOCK32.DLL,
it just exits. The way it spreads is described at McAfee.com (link
from www.sexyfun.net):
