http://myetherwallet.com users to be redirected to a phishing site. This is not on @myetherwallet side, we are in the process of verifying which servers to get it resolved asap.
I will recommend you to store your ETH very securely on hardware wallet which reduces the threat of hacking like Electrum or Ledger nano(s) is a very good wallet and dont use any soft wallets easily prone to hacking.
