TOPIC: www.site.com/component/dtregister in SE

Hello,

How to hide http://www.site.com/component/dtregister in search engines?
It goes right after my official site name if I enter my site name in Google.
I even don't publish this item in menus...

Is it possible now to let my rivals know which component I'm using on my site.

ALSO!
http://www.site.com /component/dtregister/ can be accessed from the front even if not published! I can't restrict the access to the component even if I publish it and the special access level.

Unfortunately, I think that is more a problem with Joomla and Search Engine Friendly URLs. For instance if you have acy mailing installed you can do the same with

<yoursite>/component/acymailing

try it with all of your components and you'll probably see the same thing.

Now if I am wrong somebody let me know because I would like to secure them as well.
