Im gonna buy a ledger but i still want to.spread the risk among some other wallets. Problem is most now apart frrom core uses a 12 word passphrase. Problem is John Mcafee says millions of phones and computers have keyloggers so they can take photo.and send your passphrase quite easily.
Is this a serious risk?
How to use a wallet that solves this?
Actually, if your computer is infected, there is not much a wallet itself can do to solve it. The malware could hide on the system driver level, so the application in user space has no chance to detect it. If there are wallets that claim to be able to cope with it, it sounds suspicious to me.
The risk itself is quite serious, as there are many versions of malware around that are crypted by non widely known algorithms and by that they bypass a lot of AV scanners.
Problem is that a lot of this malware has special functionality to detect if a cryptocurrency wallet is installed and it filters the data to only capture this part.
In general, linux operating systems are not targeted that often. For high-volume transfer handling, I generally recommend using a dedicated machine that is set up from scratch, where only required software gets installed. Then, you can setup a firewall to only allow a specific process to communicate out of your machine. This should give you maximum security.
Better safe than sorry...
