i think you should mail the issue to Adsense support so that you can prevent your account disable. however you cant prevent those clicks but you can prevent you account disable. inform Google they will not count that clicks.
Definitely get in touch with adsense immediately! If you report the problem they'll work with you, otherwise you'll get disabled for sure.
you put a gadget ip tracker in your blog and than you will find who any one make a fake click with out your permission
