Luckily, Ghouls retain the Necromantic vulnerability to holy or silver weapons. The most effective weapons to combat Ghouls with are holy, explosive or mercury filled silver bullets or a blessed silver sword. If attempting to kill with the sword, plate armour is advised to stop them from infecting you.

I do not know where you get your info, but ghouls are pretty much degenerate humans that are dark dwelling and for the most part are cannibalistic either consuming the living or dead corpses. More info by wiki: http://en.wikipedia.org/wiki/Ghoul

For the most part, no ghoul is the undead.
