Thanks for your answer and good advise. Right now I am running armory in a dedicated NATted old computer with a clean ubuntu LTS installation . The computer stays offline most of the time, as I turn it on only when I want to access my wallet. At some point I should move to the next level of security and start using an offline wallet.

To be honest, these security measures are an overkill for the little money that I have. But I do like following the best practices, even if it is not strictly necessary
