Use multi sig wallet.

Also, keep your BTC in a cold storage.

Finally, do NOT download internet porn.

Mate i am Muslim just to let you know, i don't watch porn let alone download it. So your sense of humour is wrong in here, although i like humour very much.

I am using local now Multibit from my Linux machine at home.

My bitcoin wallet was hacked again even protected by 2FA google authenticator and secondary password. Anyway i created a new wallet, but how is this possible Huh

if it requires google to protect it, then its an online wallet..

try using local (on your computer) proper wallets, rather than having privkeys online

Online wallets are always risky. Never keep all your bitcoins in one place.

If you still want to use online wallets, try some linux distribution that is set just only for that purpose. Maybe TAILS?

I preffer hardware wallet, but if you preffer 2FA, use very old phone without OS and internet access just to receive the SMS.

Thanks all for your replies. What i mean is i am using Multibit now, so the chances to be hacked are far far less then blockchain.info. I know Linux is not immune, but also cannot be infected with 490 spywares like Windows. No matter if i reinstall, keep Malware bytes and an antivirus, Windows still have 99% of chances to get infected. It sucks definitely.

well next time don't download to many shit, because having so many spywere and malware, isn't really windows fault

The only way the 2FA was braked was only because they knew my private key and that disable anything and permits the hacker to do what they like. Anyway this is old story now. Am sitting at my home with my new Multibit wallet, which looks as awesome as it can ,knowing here i am in Linux and no one can touch this wallet of mine. So thanks again for all your help mates.

Dont celebrate too early, because altho using linux makes you less vulnerable it doesnt make you untouchable. There has been an increase in linux attacking mallware
designed for people like you, who think that "there are no viruses coded to attack linux systems"
Just be careful mate, better make paperwallet's, just to be sure

cheers

You need an OS reinstall on any device that has communicated with that infected computer. Antivirus software isn't enough.
From a freshly installed computer reset all your passwords as well.

Here is how you do it right:

How do you store your backups?

Could access to your backups + passphrase have been how your coins got stolen?

Now i have uninstalled google, did a restart, scanned with Malware bytes , the 7 unwanted programs google chrome extensions are not anymore. Changed the wallet 2FA to email , google email which i have also via a SMS message. Am surfing with Firefox, its feeling great now with ADBLOCK , and avira browser security ,plus malwarebytes and Eset smart security latest update. I am giving a final go to my old wallet. What do you guys think Huh

(I know ,i am too stubborn but thats me)

Even doing this, you are likely not safe. If you have a key logger in there, you may still have something lurking.

You need to reinstall the OS (backup your keys and anything else that is important first). Windows, Linux, Mac OS X, whatever. Malware bytes may have missed something and you should not assume that it caught everything.

You don't want to have to go through this again, so I'd make sure that you reformat and reinstall.

Its not because you are on a Linux you're immune. Still take care of the computer that holds your wallet!

Seems like the problem is malware or a keylogger. Format your system erase viruses, the only way the 2fa was cracked was because they had access to email.

The issue is more likely local PC security related than it is to blockchain.info . If your local machine has malware or the network you are on is insecure ( sniffing, mitm, etc ), then it would be easy for an attacker to get access to your session and steal your coins. I think blockchain.info is fairly safe to use as long as you ensure the security of your local machine and network. Having an offline wallet or hardware device is of course always preferred at the slight cost to convenience.

It might be better now, but blockchain.info is not exactly known to be secure.

If your old wallet has been compromised in the past, then it is quite possible that the thief already has your private keys. This means that they no longer need access to your wallet. Any time you receive any bitcoins to any address that existed in the wallet prior to being hacked, the thief will be able to instantly remove them.

If you are determined to continue using blockchain.info, then you should abandon your old wallet and create a brand new one once you are absolutely certain that you no longer have any malware on your computer. (Be aware that malware scanners don't and can't find ALL malware).

Thanks a lot mate, then best bet is MULTIBIT. I hope it can use 1 simple address for sending and receiving as i was reading its faq and it says you can add as many addressess as you like for sending and receiving, but i only need one.
