Your brother contacted me in-game a short time ago. I would strongly advise that you run a virus scan on your computer as soon as possible, then follow the steps on this thread to regain access to your account:
Iced Ranger, I recommend that you check out the
Support - Insecure Email
page of the Support Centre. There you will find steps to help secure your computer and then your account. At the bottom of the page, there is a link to contact Jagex after you have taken those steps.
