Nostalrius Begins - Quality wow vanilla realm (1.12)

I recently got hacked and would like some help all my gold was taken of me and mailed to someone I would like to know who this person is that it was mailed to or the IP addresses of anyone that logged into my account on the 21/09/2015 as i believe i have a key logger and would have to report it to the police

I think i have a key logger on my computer that was recommended by a in game person and i need to know if his ip went onto my account because if he did i need to report it to the police

Thanks Kurzol
