I got a molar extracted last Friday and although it doesn't really hurt, there is some white gooey stuff on the blood clot and it smells horrible. I'm not sure what it is. Should I remove it, or would I be dislodging the blood clot? The smell is really bothersome.

That is dead tissue and you are supposed to be gently brushing the gum top and all around - didn't they tell you that, or give you a set of instructions? Also gargling warm salt water as often as you can, even once an hour.
