Today I have sent a little Ethereum to my address but it instantly transferred to another address. Later, I tried again sending 0.002 ETH and the same. It also transferred that same address instantly.
How to get solve this?
I have seen this kind of thing happened before, though it was to my bitcoin wallet and not ethereum, but I think you wallet has been hacked, what the hacker did you that he/she wrote a script that will monitor anytime you try to send money out of your wallet, and redirect the coin to a wallet specified by that hacker, all you need to do now is try to sweep the private key in another wallet because the more you try sending, the more you keep giving the hacker your coin, try what I just told you to do and give us feedback.
