To be honest, hackers are more advanced than us. On the other hand, hackers can't get control of your device without your help. For example, during install a new apps it will ask for permission, did you ever noticed what permissions have been giving? Most of virus enter on our device via software and suspicious links (especially from porno sites). So we should prevent such as attack in order to protect our cryptocurrency.

I will not suggest to use paper wallet due to various reason. Only use hardware wallet to keep your cryptocurrency safe. But of course you have to prevent virus as well they could get control of your clipboard. No system are safe, always double check your addresses during sent fund. Don't store your fund on exchange for long time to avoid attack.
