In this case nobody can be sure his bitcoins are safe.
Cool wallet on the paper is a good thing, but...
You make new wallet and write it on paper and put 1 btc into. After 1 year you will need put another 1 btc there, but you will not shure has your wallet the 1st 1 btc or not for some reason.
You'll need to synchronize core to be sure the your wallet has the 1st 1 btc.
If you are not sure it is a not very good idea to put your other 1 btc

The best way is to ensure that it is safe is probably to generate it offline and make multiple copies of it. When you spend it, send the change to another newly generated address from the offline computer.

You don't need to use Bitcoin Core to make a cold wallet. Electrum with a raspberry pi would be sufficient. Put the transaction info into the USB drive, go to your offline raspberry pi to sign it and broadcast it on your online computer. All activities on your Bitcoin address can be tracked easily using a block explorer. All the activities are recorded there and it is easy to check the balance with only your address.

The only secure way to use Bitcoin Core is with Armory in cold storage mode. Needs two computers though. If your private keys are not permanently offline you are ripe to be a victim of malware sooner or later. Get a Ledger hardware wallet for $20.

It's a good practice to note down the address (Not the private key!) your long-term storage coins are held at. That way, you can check the BTC is still there on blockchain.info or any other block explorer site with no risk of compromising your private keys.

The real issue is making sure your private keys stay safe in the first place. For sums like you unfortunately lost, you need to be quite careful. Using a freshly created linux USB to create your wallet, and generating the keys offline, writing them on paper and then wiping the USB boot disk should be a pretty good solution. If you want to run a Bitcoin client and intend to ever send BTC to a wallet on that client, you should have a computer completely set aside for that purpose, in a safe space. Do not run a bitcoin client on your day-to-day computer. I wouldn't trust anything other than a fresh install of an OS to run a client on. Preferably a fresh computer as well, if you're feeling paranoid enough about rootkits etc.

Sorry for your loss. I wish we could help, but it's probably all gone now. If you still have BTC elsewhere, make sure to secure them very well.

I had the 1st wallet. Then when the sum of bitcoins was pretty big I've made the new one (about 3 years ago). I've transfered the bitcoins to the new wallet 1 time and keep them there. For the new bitcoins I've used the new wallet.

Just to be clear:

The new wallet is the one that has this address in it:
https://blockchain.info/address/15ESHhWuNfqMEQPXWexGb9kK1J53brWksL
correct?

And you created this wallet 3 years ago. You did not transfer anything to this new wallet until November 4th, 2014. Correct?

If that's the case, it seems your keys have been compromised some time over the last 3 years, and the thief likely just waited for something to be transferred to an address controlled by those keys. This would, to me, suggest an automated system to check a number of compromised keys for new BTC, which in turn would suggest a relatively widespread virus of some sort being how your keys got stolen.

In this case nobody can be sure his bitcoins are safe.

With Bitcoin you are the boss! That not only means you are in charge, but that you must work. Bitcoin security is no better than your security. If used correctly it is miles above the bank's security system. However if you do not protect your private key then no other methods matter.

I don't know how this happened to you, but someone must have gotten that key. Consider who else has access to your computer. Think about where you store your private key. This breach may not involve malware at all. Also, Think about a more secure OS like Linux.

Sorry to hear about your loss.

Look at the picture from my 2nd wallet:
http://tinypic.com/r/ddsw0/9
There is no address in transaction. The label "нeдocтyпнo" means "no acsess"
It seems it's pretty strange

No information about the transaction? That is strange. You did a lot of things right, using the long password with no words. That rules out guessing your password. You are using good anti-malware. That makes malware a little less likely.
If you wrote the password in a document or on a slip of paper you may want to check the security on that document. It may also be worth asking yourself "who else knows I have bitcoins and has access to this computer"?
What a bummer. Can blockchain.info give you a Tx ID? That may give some more information.

Possibly a password theft if your password is too easy to guess (several words you always use) but in order to steal your coins, the hacker must also have access to your private key. In fact there is no 100% sure way to make sure that no one else have your private key unless it is generated by you manually and kept offline secretly

The entropy in core client should be strong enough to avoid key collision, but the key should be generated offline and kept offline most of the time

The passwords were about 30 simbols and didn't contain whole words
I've never entered the passwords for many mounthes

It is possible that your private key is already stolen before you set the password. For example, some Trojan has been installed before you install the core client, and they constantly searching for the wallet.dat file on your c drive. Once found, they immediately send the wallet to the hacker, and that is before you even set the password

In this case why they didn't steal it 3 years ago?

The isn't a bitcoin issue, this is a computer security issue. If you can't secure the computer, nothing that the bitcoin developers do will help stop it.

If you can't secure Windows, use Linux or OS X or any number of other OSs. And use them ONLY offline. Or use a paper wallet. Or a hardware wallet.

Did you transfer any BTC to any address controlled by the private keys in question before this? Or was this the first time you sent BTC to this wallet?

If it was the first time actually using that wallet, it seems likely your private keys were already compromised before you reinstalled your OS. So how secure was your setup before you installed Windows 10? Were you using that laptop for anything other than running a Bitcoin client? When you first installed the client, how confident can you be your system was clean at that time?

I had the 1st wallet. Then when the sum of bitcoins was pretty big I've made the new one (about 3 years ago). I've transfered the bitcoins to the new wallet 1 time and keep them there. For the new bitcoins I've used the new wallet.

I've made clean installation of Windows 2-3 times since I've entered the passwords last time.
I hope the investigation of this case can improve the Bitcoin world and can prevent such incidents in future

Did u use any external devices (usb) which were used on the (maybe) compromised system after the clean installation?
Or did you only use new usb sticks / no at all?

If your going to get BTC again.. get a hardware wallet and initalize it on a linux distrib.

it is best to avoid windows 10 right now, but i don't think this is the case, of the first hacking attempt from microsoft, so it most likely that you were infected

you visited a shady website or probably downloaded something malicious, in other words it's your fault

What about the passwords?
I've never entered them on Windows 10

You had quite a considerable amount. Have you ever revealed how many bitcoins you have publicly, on any forum for example? This would make you a much easier target. Hackers would be able to target you by your IP address.

The truth of the matter is that these Bitcoin targeting malwares are and will be more and more numerous in the future.

As long as you don't port forward everything, there is no risk of you getting attack by your IP address. Vulnerabilities may be possible but I haven't heard of any for Windows that is this critical.

rootkit maybe? your system was already infected long time ago, and the hacker waited for a big amount? it is certainly possible

Certainly what I'm thinking too. The hacker might have gained control of the private key and run checks every x minutes to transfer the Bitcoins.

31 Bitcoins ($ 12,090.07) What a huge amount of loss to Edward.

Yes there is! For such a huge amount, OP should have used paper wallets or have bought a hardware wallet like a Bitcoin Trezor. Any of these two combinations is perfectly safe and should be used for anything over 7-8 coins in my opinion.

OP sorry for your loss by the way!

Your system is definitely compromised. Best thing might actually be to do a clean install and get a new set of private keys.

Whatever you do, do not touch your keys ever again, the hacker will always have access to them.

It indicates that he will never get his bitcoins back again?
He can't complain regarding the issue to somebody?

The chances of him getting those back are slim to none.

There is always the possibility that it was someone close to him that had physical access to his pc at some point.

There is no official Bitcoin wallet, the reference client is Bitcoin Core if that is what you meant.

The coins were sent away in an hour after the payment was first received. You did not have any Bitcoins when you typed the password 6 months ago and hence it would be possible that a script was designed to transfer your coins away once a payment was detected. It could also have been compromised when your wallet was first installed. It looks like the address sent to was a mixer and hence it wouldn't be possible to tell who stole it. Antiviruses aren't 100% accurate and it is possible for them to miss kinds of virus infections.
