simply append the folder tree to the absolute path of your website. eg: if your forums are at www.yoursite.com/forums/ and your absolute path to webby was /home/sitey/public_html/ then the absolute to the forum would be /home/sitey/public_html/forums/

2/ I've try to fix the problem by uninstalling the component and try to upload it again but even if the component has disappeared from the administration board (Joomla), I can still found a folder com_v-bridge trought the FTP and I can't delete it : "access denied" (the folder only contains 2 files : index and installation)
How can I delete it ?

you may need to change permissions on the file. Use an ftp program like filezilla and change the attributes on the files to be 777 so read and writeable by all. Then try deleting. (right click on the file for contextual menu in filezilla to do that).

In this case, I'll need to have the mainmenu of JOOMLA at the top of the forum, just like this : http://forum.joomlafacile.com/.

Can you tell me how can I obtain this result

View the source of your joomla page and copy the header data over to the header template in vbulletin. You'll need to adjust things a little bit, but that's the jist.
