client denied c:/wamp/www/favicon (no replies)

Hello
How can I solve (and remove) the following error in apache_error_log :

access_compat_error - AH01797 : client denied by server configuration c:/wamp/www/favicon.ico

(I'm using Wamp 2.4/ Apache 2.4.4 Win 32 on a XP SP3 machine)

I created an alias. So I never access to wamp main 'www' directory, but only to my alias [<my] ip>/<myalias>/

So why apache is trying to get access to main 'www/favicon.ico' ?

And I don't want to give external access to that main Wamp 'www' since I don't need it ?

And I was not able to find a directive to ask Apache to not search this favicon.ico or to not log this error that increases uselessly the apache error log file.

Thanks
