Four Questions about Lumia 950

[lumianum]

It's actually five, after an edit. Some questions regarding my new Lumia 950, which I would appreciate you answer by number. Thank you!

1) Do we need to install an anti-virus ?

2) Should I buy a protective case? I'm most concerned about drops and getting the screen shattered. Which cases would you recommend for this purpose?

3) Do you use a tempered glass? Does it affect touch response or screen colors? Is it possible to put and remove as many times as I want, or it can only be used once?

4) Some times (very rare), Windows Hello fails to recognize me, so I swipe up to enter the 4-digit code, but instead, it unlocks directly, without asking for the code. Has this happened to you?

5) How do you clean your screen? Just water on a piece of cloth?

Thanks!
