I downloaded from the official website, but I found a malware "remcos" on my computer, and they keylogged everything.
I traced the stolen bitcoins to Binance, unsure what I can do from here.
It doesn't cost you anything to inform Binance and see where it takes you.
Regarding malware, I'm gonna guess you're a Windows user. Stop that and switch all your crypto activities to Linux.
While I really love Linux, advice like this doesn't accomplish anything, makes you sound really elitist.
You can safely use a hardware wallet and be a Windows user. Even using desktop wallets is fine 99% of the time, if you take some basic security precautions.
Usually wallets get hacked because the user installed malware that he downloaded himself, direct attacks are very unlikely, especially if you don't have a big amount of coins.
If you have a big amount of crypto assets, invest in a hardware wallet.
Another important thing to note is that an unconfigured Linux desktop might be a bit safer than Windows by default, but it's not completely safe either.
An uninformed Linux user can do much more damage to his own system than an uninformed Windows user
