when i mouse-over the adress that is linked it says it actually goes to "www.blizzard-accout-info.com" and should i click it, my internet browers imidialtly reacts and tells me is an insecure location and strongly recomend me to not go there, i click the "show more details" and it says its a fake site that is a copy of other trusted site that might steal my personal or economical information.

now after all this something is still very unclear to me..... is the email actually real or fake? the adress is real accoarding to that guide, so.......... whats going on?
