I have no idea which of the following is correct (or at least, better to use):
- I am not going to hurt you, but I am not going to protect you either.
- I am neither going to hurt you nor protect you.
- I am not going to hurt you, but I am not going to protect you neither.
Is there a general rule for not confusing between nether and either? I remember from my English classes that either is for positive sentences and neither is otherwise, but does it literally means a sentence with positive and negative verbs or what?

Using "neither" can be tricky, so in general, you can stick with "either" and never use "neither". Even native speakers frequently use it a way that goes against formal grammar rules.
Your first example is fine, and again you can stick with using "either" this way, even if the context is negative.
As in your second example, the "standard" way ensure you use neither correctly is to pair it with "nor". Just like you would use "either ... or" to create a list or choice, you can use "neither ... nor" to create a negative list (or lack of choice).
Your third sentence is an example of vernacular -- this construction shows up in various dialects, but it's not "formal" English and so I would recommend against using it. However, the only thing wrong with it is where you place the "neither", which should be in the middle, and you have to reorder the subject/verb pair:
I don't know if there is any actual rule for this. It may just be another English structure that you can memorize and use as needed. Other examples:
