Wordpress plugin directory shows up in big G

Specifically -
.../wp-content/plugins/sexybookmarks/spritegen/media/

I can make it as high as /wp-content/plugins/ before it stops showing me the data. Is there any way to close this off? I just did a G search on /wp-content/plugins/sexybookmarks/ and there are ~40k results for it (so I'm certainly not the only one).

create htacces and add this and upload

AuthName "Restricted Area"
AuthType Basic
AuthUserFile /home/.htpasswd
AuthGroupFile /dev/null
require valid-user

Thanks man, I'll get em patched up!
