It's really simple. Use MyCrypto instead of Myetherwallet. It's made by the same team, It looks the same and it has more improvements so there is no reason why you wouldn't use it.
I haven't seen a single phishing attempt yet targeting Mycrypto, most likely because hackers are not really aware of it as of now as not many people use it. Either way, the domain name is shorter so It's unlikely that you'll fall it.
I think if you want to avoid MEW phishing or any e-wallet phishing site. You should have knowledge of security in basic. I still using the MEW 2 years, and I have the habit that always bookmarks MEW to the bookmarks bar. I think this avoids the phishing scam website to steal your private key.
