Since a 400 error means that the server cannot understand or handle the request because it is malformed, and since most of these malformed requests come from badly-coded site scrapers, data miners, vulnerability probers, and e-mail address harvesters, there is not much you can or should do about it.

You cannot stop these invalid requests from arriving at your server unless you have a firewall on your server and can modify its settings, and they are logged by your server only 'as a courtesy' to you. So, you can either ignore those log entries, or set up custom logging on your server (if you have the privileges to do so) to prevent requests resulting in a 400 status response from being logged and ending up in your 'stats'.

But personally, I'd rather know when my site is being scanned by a wanna-be harvester, so that I can investigate the originating IP address range and block it if appropriate.

its very simple to redirect your 404, 400 and other page.
create a .htaccess file on your root
and type below
ErrorDocument 400 /404.php
ErrorDocument 404 /404.php

be sure 404.php file must be exist.

thanks
