Get a Ledger Nano or Trezor hardware wallet.
If you can't get hold of the hardware wallet. Get the desktop wallet in https://litecoin.org/ website.

LTC is not in the Ethereum platform and your LTC will get burned if you transfer it to an Ethereum address.

I just realized that lots of people here in bitcointalk are:
1. Do not even read or are not aware of the different platforms - hence the recommendation by some to use MEW 
2. Post or recommend responsibly. If you are not knowledgeable on the subject, please do not give a recommendation, you'll confuse the OP and made him/her lose their hard earned funds.
