Not saying that it is going to happen but if the virus has the ability to copy it into the USB, install it in the offline computer/copy the important files, go back to the online computer and send it to the internet, you would be messed up. The QR code shouldn't have any backdoor since it is opensourced and you can check the qr code for anything. The hard disk idea wasn't very good since hard disk have limited lifespan and can be spoilt after some time.

USB may contain MBR viruses even after formatting.

Wow i didnt know about those, thanks. Are you a computer scientist?

Also this doesnt solve the problem it only makes it more imperative. Since the same way as you install the bitcoin core or armory into the offline PC you can also put the virus there on the first install.

Also if you then decide to put an antivirus on the offline pc then you can also slip the virus in together with the antivirus..

So it seems to me there is no 100% security out there. What do you think?

That would cost you a good amount if you continue it for a long time. You could buy a Ledger or even Trezor instead of buying CD everytime you send BTC.

Yea but i`m not talking about 0.01BTC either, i`m talking about 10.000 posibbly 100.000BTC to be managed. When you own that amount of funds then you have to pay additionally for increased security.

Hank is a known person and he created android litecoin wallet which is widely used litecoin wallet. He has also created a few other things such as litcoinj and feathercoin wallet. So if he really want to put a backdoor, he could have put in that wallets.

However, it is good to check more about that program by checking the code(if you know the language) or by checking reviews from trusted persons(least recommended).

It could not be intentional though, many softwares can be infected unintentionally though. That's why i scanned my own softwares that i made with 4 different antiviruses to make sure nothing slipped inside it. Even if i made the code 100%, there could be the possibility that a malicious resource file copies itself into the assembly.
