If I turn off exp share and go into battle, will EVs still go to others not in the battle?
No. Any Pokemon that gains experience (or, for level 100s, otherwise would have) gains EVs for the battle.

and if one of my guys have pokerus will it still spread without the exp share on?
Pokerus spreading has nothing to do with EXP Share. It's either getting into a fight with an infected wild Pokemon, or being in the same active party as an infected Pokemon, that spreads it.
Now, if you have a Pokemon that has (or had) Pokerus, it will still double EVs that are gained because of EXP Share.
