I would recommend using a thumb drive bootable edition of ubuntu for your savings account. That way every time you access your savings wallet, you are on a fresh copy of ubuntu and any trojans you may have gotten with your main OS will not effect your savings wallet. I put a guide together for all of you who are reading this and don't know what I'm talking about.
