I have been running without any protection whatsoever for the past 8 years, and have had a total of 5 viruses

You think you've had only five.  The danger is on the ones you don't know you have.  :-)

Nice guide will refer to it when I have enough bitcoins to be worth stealing. Nothing will ever be 100% secure though, but if you rounded upwards the claim is probably correct. Cheers

What are the chances that say you buy 10,000 btc and the market completely dying.  I mean is btc worth investing in and using and saving your money that way?  I'm interesting in doing so, but a year from now I don't want ten grand worth 1 grand.

100% secure doesn't excist D:

That's quite true, and I think the subject is misleading. However, I do think this is a very good guide for decreasing the probability of your bitcoins being stolen.

Thanks for the info. I try to keep mine off on a physical USB device and use at least 3 of these devices in case 1/3 or 2/3 get lost.

I don't think this is good advice....sorry...I think a much better idea would be to create an address & private key pair on a "live" OS, write both down on paper, attempt an import into a wallet to prove you copied correctly, and then reboot to "hide the evidence"...Now, if you are really nuts, memorize the private key and 6 or so initial chars in the public address (in case you don't trust your paper or ink)...put your paper with the public and private keys in a safety deposit box...That's way more secure than optical or magnetic media (which will degrade faster than paper) and way more resistant to cosmic rays than solid state media....obviously nothing is invulnerable to physical attack Smiley

Since everyone is posting how they do it I'll add mine. I only have a few Bitcoins so I think this is adequate.

I'm using Ubuntu and gnupg to encrypt the wallet file automatically when I start the client. I'll share my small script for this below. I just edit my Bitcoin menu item and replace it with the name of my script and my personal key id (either name or number but name may need quotes).

eg. script saved as /usr/local/bin/gpgbtc then I call it with "/usr/local/bin/gpgbtc 249AD24C"

Gnupg is already installed by default but for my script you need two more packages. I use "srm" to make sure the non-encrypted version is toasted nicely and I use gnome-gpg so that I can get a gui password prompt.

sudo apt-get install secure-delete gnome-gpg

/usr/local/bin/gpgbtc (be sure to chmod +x so it can be run)
Code:
#!/bin/bash

gnome-gpg ~/.bitcoin/wallet.dat.gpg
chmod 600 ~/.bitcoin/wallet.dat
bitcoin
mv -f ~/.bitcoin/wallet.dat.gpg ~/.bitcoin/wallet.dat.gpg.bak
gnome-gpg -r "$1" -e ~/.bitcoin/wallet.dat
chmod 600 ~/.bitcoin/wallet.dat.gpg
if [ "$?" == "0" ]; then
  srm -fllz ~/.bitcoin/wallet.dat
fi
This script prompts for your gpg key password, decrypts the wallet file, runs Bitcoin. After you close Bitcoin it makes a backup of the last wallet version, just in case something happened, re-encrypts the wallet, and securely removes the decrypted version. If Bitcoin doesn't close properly then it tries to detect that and leave the wallet file for you to check manually.

So far this has been working fine for me and I keep several back up copies of the encrypted wallet (and my gpg stuff too). But if you choose to do like this do so at your own risk. No guarantees from me or anyone else.

This is just for those who may want to do like this but not re-invent the wheel.

I'm with the others for the idea of simply encrytping the entire OS. The Live boot CDs are somewhat more painful in the long term, due to long load times and needing a USB to persist settings etc. Of course anyone assumed to have the knowledge or skill to do the OS encrypt is also clued up enough to practice safe habbits of web surfing and avoiding trojans.

Live CD is a safe resort, but inferior to the OS encrypt I do agree.

Frankly, I love the dry wit of an Englisher. Being able to use words like twat and cunts in an actual coherent sentence? Priceless. This is the type of post that should be made sticky, but then in my case it is, I snorted iced tea out of my nose when I read it, and now the whole damn keyboard is sticky, not just this invaluable post.
