I have very nice idea for admin/forum members in their free time, who are very experienced in everything. Try to install Qubes OS ( Fedora Linux )
http://www.qubes-os.org/ in your computer, and then your hard wallet. Here is also one good example link for this:
https://forum.qubes-os.org/t/ultimate-guide-on-using-trezor-on-qubes/18310.
Or just install Qubes OS ( + can be also Windows OS or another Linux ) for testing and Bitcoin/altcoin wallet using.
I did not use Qubes OS yet, so will be nice to hear their experience.
