Hacked and don't know where to start

[yasoo]

HY my website has been hacked 3 days ago, i had a weird payment CB form appearing in front of my installed payement modules and it dissepeared when the form was filled and then refresh the checkout page from the beginning and showing the installed payment modules of the site. The BO also took 10 mns to open.

From now i've uninstalled all payement module and yet this form has disseppeared, i can't install any new module as i have an error signal in the BO saying that "....config_fr.xml could not be loaded." The BO opens in the right way.

Can anyone give me a way to work to clean this out and make it work again cause right now i'm reading every hack symptoms on the forum. If someone have the clue or an indication to what i should first work on it would be help full for me.

Any help welcome.

Thanks for watching
