Hacked bitcoin account. I believe that my account was hacked: a "send" transaction occurred on my account an hour ago and I lost $62 without my raising any transaction. The transaction is still unconfirmed, how do reverse it and get my money back ? Standing by. 
Recipient address-https://blockchain.info/address/18VhGJQgvYVpGLfZPJ1wu85JDAJ8UU6A62
Transaction hash code - https://blockchain.info/tx/ae97308ffd3e460ec4d928d5309479351220b30811d7e02f2a571e23d38e48d2

Once more, I did not make this transaction,and $62 disappeared from my account. Please help.
Bitcoin transactions cannot be reversed - unless you are sending coins to someone you know by mistake and they are willing to send it back - which in itself is also relatively unlikely.

If someone has sent money from your account without your knowledge, then they have got hold of your private keys. What wallet did you use? Is it local on your machine? Is it online - in which case you may have not set a complicated enough password.

Sorry about your loss but you need to make sure your wallet is secure in order to prevent this from happening again.
