If you have more than 1000 Bitcoins in your wallet:

1. get yourself a low cost netbook.
2. Install not bloated linux (like archlinux) or FreeBSD or OpenBSD (in order of growing paranoia).
   - make sure that the above is done with ecrypted partitions and swap (plenty of guides on the net).
   - make sure that the above is done while offline as much as possible (for truly paranoid ones).
   - make sure that you do not not even configure wireless hardware, let alone using it
   - physically plug in Ethernet cable when you need connectivity for a minute or so
3. Install bitcoin client, generate a bunch of bitcoin addresses (current account)
4. Over time transfer in small amounts your funds from your existing client to the addresses created in step 3
5. Keep this used exclusively as bitcoin client and nothing else, plug in Ethernet cable when you need to transfer money.
6. Keep this hardware wallet safe.
7. Creating a bitcoin savings account and making secure backups is still need to be done as described in multiply guides elsewhere.

P.S. Do not forget your passwords.

this spoke to the paranoid hiding inside me, thanks!

I would suggest doing this procedure if you have any number of bitcoins.

thanks for the info, but I do not think, that a antivirus protection can help. If you look at "blackhat forums" you can find for a few dollars progs that can not be detected by actual antivirusprogs. Only help: Use your brain and encrypt.

Do these still effect linux users?
If they install a program that steals their wallet, yes.

I use block chain as I have found it to be the best and a very reliable wallet. It even lets you withdraw btc to your local currency (at slightly lower than market rates.)

Use Armory wallet.  Create an offline wallet.  Back it up several times, including a paper copy.  Send BTC to wallet.  Sleep well at night!!

Is encrypted Bitcoin-QT as good as Armory or Electrum?

Wait, this thing is still around? Anyway, the best way to "secure" your wallet without really securing it, is putting it on a computer that never gets used for anything. Build a computer, put an OS on it, then just put a wallet with whatever dependencies needed with it and there you go. If Windows, keep it updated through windows updates, linux with its package manager, but don't do anything else with it. Now it is (for the most part) only vulnerable to attacks from other computers on the network. But if it's also on its own network, then you're golden. Not immune, but it's a massive step forward, and encryption isn't even needed. Only turn the computer on when you need to take coins out of the wallet.

A barebones machine like this, that has never even opened a browser, would indeed be about as safe as you could get. More safe than any machine with any antivirus that has connected to the internet at some point.

Even with this barebones setup...
Isn't sending from or receiving to the client also a potential vulnerability? If so, then what is the benefit of cold storage clients?
Can your computer get infected with a trojan when the Bitcoin client connects to the internet or are viruses only transmitted through browsers?
