How can I figure the person who owns the address to give me my money back? And what can I use as proof if he refuses to do so?

Understandable. Yeah, I lost it 

I will surely scan for these buggers, it's VERY likely this was a malware attack, with copy to clipboard kind of thing. Amazing how they can do that easily.

Well, I'll see a way I can pay this loan. Thanks for all the help.

It's just... disappointing to have this happen, you know?

Hello. This is my first post here, I hope it meets the standards of the forum.

The situation goes like this: I have a loan to pay, that has to be exclusively in bitcoins. I used LocalBitcoins in order to buy an amount of 0.3191 BTC with a seller, and it worked. However, when I was about to transfer the money to my account, something went arwy and the address had changed COMPLETELY the address to receive (malware, perhaps? Although I think it's unlikely), and it now it has went to someone else's wallet. I am desperate, angry, frustrated, and helpless. I know transactions are irreversible, but I just wanted to ask for help, somehow.

Can anyone help me out? I contacted the seller and the website, and no way to revert things. I don't have a way to contact the wallet owner, so I guess I lost the money, yes?
