I guess I download a virus altcoin wallet and the hacker found my private key in my desktop
You cant do anything now. It was a valuable lesson for you that you paid for. The main thing is that now you need to make the right conclusions.
Never use this wallet. You need to remove this application from your laptop, clean it and check it well for viruses and malware. Use the metamask to create a wallet and use it.
