dont download, dont install anything ...
Do you have proof that there is virus? You can try to check it with ANYTHING it is 100% clear
Do you have proof for the 1BTC/day from your BOT?
even if you got 1 btc , it doesnt matter because bitcoin2048 wont pay you, they got a pretty interesting record of not paying the high balance since few months ago, so basically you are risking it by downloading an unknown application and even if it is legit, you wont get payment from bitcoin2048
