Wallet Security on Windows

[matt.collier]

Hello Developers, thank you for all your hard work!

I currently make a living removing malware from Windows systems.

I know that I am not the first to suggest that there will be (or already is) malware designed to either steal wallet data or just send all the victims bitcoin to the authors own address.

I've been reading that we'll be seeing encrypted private keys in memory and on disk. 

Is that going to be the main line of defense against such a threat? 
Will we be able to specify a "key file" instead of or in addition to a password?
Any idea when this feature will be incorporated into the stable release available on bitcoin.org?

Wallet encryption is being tested at this time. It won't protect you from malware that keylogs and copies the wallet. As someone accumulates wealth a safe method is needed. It would probably be some type of Live CD operating system that can only run bitcoin for sending and receiving money with the wallet encrypted.
