What to do:

1.) Don't be a relative of Myers

2.) Never board up the house or lock yourself anywhere with other people unless you are 100,000,000% sure that Myers isn't in there

3.) Don't go trick-or-treating

4.) Give yourself insomnia so you can always be on guard

5.) Do NOT lock or isolate yourself somewhere alone

How to fight off:

1.) Sorry but if this is Michel Myers we're talking about, there's not much we can do since he will come back XD

2.) Having an RPG wouldn't hurt.

3.) Or a Death Machine

4.) Or a Ray Gun

5.) Ask Samara how to get into the world of Black Ops Zombies and just borrow the guns from there XD

How to at least survive:

1.) Join Myers in the killing spree

2.) Call the F.B.I. or SWAT team or the freaking whole entire American army to gun down this guy!

3.) Call Kim Jong Un and ask him to nuke Myers instead.

4.) Call Jason and put the two in a battle.

5.) To do the above, get the two to argue over who's hockey mask is better *cough* Jason's *cough*
