Were you using the same password for your Cryptsy, Gmail, and Blockchain accounts? Did you not have two factor authentification enabled on any three of the aforementioned accounts? If yes, you have no one to blame but yourself because this was bound to happen by not taking security seriously. If no, you should probably ditch the Symantec for a product that is capable of protecting you from a keylogger, or you should simply avoid malware sources altogether..

Edit:
Wallets are a pretty mainstream concept at this point in human history, but if I remove your ID from your wallet, the wallet and its contents are no longer linked to an owner.
