All of the hits are originating from China as you can see and all to register.php and register.php/register.php and only started in the last 2 months.
I am thinking this is some bot trying to register, my hosting providers suggested solution is change the name of the pages, but is that possible and does it really solve anything?

Can anyone think of a possible way to kill off this attack before I am penniless?
