I've registered on this site (using a temp-mail that apparently doesn't also require any confirmation) and was given a file with the source address https://zeldacoin.club/ZeldaWallet.exe. This will be obtained after clicking the login button (basically it can only log in through the app and it seems they deliberately hid this download link on the homepage).
So far I haven't installed this app yet. Can you be more specific in the app content (accompanied by screenshots) about your suspicions?
