Is this your address where there is around 5 btc right now? If so than transaction showing that $3 may only be some glitches in their script if you can still see those 5 bitcoin in your wallet still than i think nothing to worry about.
That Address is the Thief's not mine.
However in my Wallet it says Value at time of Transfer was only $3.00
Here is the Screenshot showing what I mean.
If we can track down the thief when they try to put this on an Exchange maybe we can
stop a hacker that we have reason to believe has stolen much more than 5 BTC overtime.
Funds security in bitcoin is 100% on the user. You are your own bank in bitcoin and it's your duty to safeguard your coins.
Let me start that you cannot safeguard them by keeping them in an online wallet. Histories like yours happens everyday with blockchain.info and the best solution is to transfer all your remaining funds to a new desktop wallet like Multibit or Electrum.
Before installing any of these, scan your PC with an internet security suite , a well known one to be sure you don't have any malware or keylogger on your PC.
Also to keep in mind is to not click suspicious links that come in your SPAM folder of your email, or download any shady software from any shady site. If you stick to these rules than it's extremely highly unlikely that you are going to be hacked again.
I talk from personal experience, I lost 600 or a bit more USD back in 2014 in blockchain.info and since then moved to Electrum. Everything fine in these 2 years using it without a problem.
For ultimate security
www.ledgerwallet.com , it's a hardware wallet which is malware proof which costs 15 Euro and about 6 Euro transport all over Europe.
I write a bit long about this issue as these kind of problem is happening here almost everyday. It's simple, just move from web wallets to desktop ones as a beginning and then if you feel like it buy a hardware wallet.
