Hi bitserve,
How is a paper wallet not protected if a pc is compromised?
Paper wallets are vulnerable at any of the following moments:
- When created: Private key generation vulnerability or PC compromised.
- When redeemed: PC compromised.
They are also vulnerable in case of physical compromise during storing.
It seems the security vuln in Trezor firmware would also require physical access plus a not so simple firmware update with a hacked firmware to get access to private key.
Anyone concerned about potential physical exploits should go Ledger way. The secure element is a great enhacement in that aspect.
Armory talks about lots of security issues in their glacier protocol

https://www.bitcoinarmory.comI have a clean laptop that never sees the internet or wifi, it's got Amory installed, and creates transactions offline, these are broadcast from an online machine that I use for everyday things and it doesn't really matter if its compromised. (transfer transactions between machines using a USB stick)
You can create and redeem paper wallets with very nearly 100% safety,
