I used MEW web for creating this address. My tokens are there which worths approx $500, I had sent ETH for gas fee and those ETH are instantly going to another address.
And this
another address is not associated to you, right? Then I might say, that there is/are someone who has access your private keys which your address is not safe to use anymore.
But I wonder why your token isn't move yet from other address while someone got access your keys.
