If anyone else is getting the same as me.
I believe its one file to edit

Go into the Bad Behavior folder and find the responses.inc file
Open that with wordpad etc and look for

'00000000' => array('response' =>

Its about five lines down from the top

I have changed mine to

'00000000' => array('response' => 403, 'explanation' => 'An invalid request was received from your browser. This may be caused by a malfunctioning proxy server or browser privacy software.', 'log' => 'Required header \'Accept\' missing'),

I was tempted to change it to this

'00000000' => array('response' => 403, 'explanation' => 'You do not have permission to access this server.', 'log' => 'I know you and I don\'t like you, dirty spammer.'),
