Regardless as to where you got it or the feasibility of getting it from a pic, you should run a full Sophos scan. If that doesn't work, try avg for-mac.
As for your account chars and items, only kabam can help you but I doubt they will even if you aren't guilty of using hacks. Maybe you got "lucky" and it was your girlfriend who did it. (having the girlfriend being the lucky part)
I don't believe malewarebytes supports mac....
