To everyone saying they bookmark sites to prevent this from happening - bookmarking rather than searching for the site every time you want to use it can help, but be aware that it isn't foolproof. Be aware that there is malware which exists which can change your bookmarks or redirect your browser from the legit site to a fake one. You should be manually checking the URL of every site before you log in.

Also, if you add these phishing sites to your hosts file as I have detailed above, and your browser will flat out refuse to open them.
