Google Chrome Extensions & Plugins

N360 21.7.0.11. Hi.

I've change my browser from IE to Chrome, and have been examining and evaluating the associated extensions & plugins.

Questions:-
     1. Chrome has an "enable phishing and malware protection": do I have to have this enabled, as I'm running a full Norton 360 package ?
     2. I've seen "phishing & malware protection" on various extensions & plugins. Do I really need these extras enabled ?
I have noticed that, the more you enabled the extras, the more the pc slows down.

Be safe out there !
