you cannot copyright a proper name, otherwise all the Ronald McDonalds in the world would never be able to write a check,get a drivers license or sign a document. You can register it as a trademark but there are different rules that apply.
Im not talking about copyright
The logo on the site is trademarked
The name John McAfee is just a name for example the site http://johnmcafee.com/
is owned by a guy called John McAfee so there is no issue there however the OP is not called JM so has no right to use that name, try registering a famous persons name and see how quikly it will be taken away from you if that person makes a claim on it.
Long gone are the days where you could do that.
