VPN
Anti-virus software
While these are not directly Bitcoin related, I do see benefits in telling more about them (or at least some of them) to the world. However, please do some research on the forum to avoid duplication; because there were discussions at least about Password managers and 2FA apps, but I don't know if a proper presentation/comparison was done.
In the context of anti-virus, also the possible benefit of having a separate Linux (partition, VM or WSL) only for transactions could be part of discussion.
And I would also like to see a discussion about VPN - which worth using and why - and a comparison(?) between VPN, TOR and use of proxies (free/hacked or not).
