Are bad spirits real
It was believed that trees had spirits and to invoke those spirits you would tap on the tree, "knock on wood". The practice tended to be a way to ask the spirits to intervene and save you from a bad out come (bad luck). This is why when you say something you do not want to come about you "knock on wood."
Ghosts are not good or bad themselves. It depends on the nature of the person whose spirit they are beholding.
Yes. Knocking on or touching wood keeps the bad spirits at bay. Yes it is a superstition.
Spirits can be either good or bad. Bad spirits only stick around because of there terrible death, and want there murderer to be avenged. Good spirits rise and fall back into the dead often, usually to check on loved ones.

Because he is Holy and bad spirits are not.
knocking on a door means your asking for someone. if you knock on wood, it means your asking the spirits to spare you from bad luck.
Spirits don't exist (if you mean, like, ghosts), so there can't be any "good spirits" or "bad spirits" giving off warm or cold sensations and feelings...
