Fake E-mail or not?

Hello, I have received an e-mail which obviously doesn't look like a keylogger scam, though my security programs warned me not to enter the given link, even my anti-virus came to intervene.

This was the following e-mail by noreply@blizzard.com (Know in advance that I have absolutely NO IDEA whether noreply@blizzard.com is official or not.)

Greetings!
