Dear you don’t need to worry about much – if its a fresh installation and you don’t have any data on your website – eg post, article, images or anything then I prefer you t install a clean fresh wordpress again from the sketches after a complete scan of your hosting.
and if you have data in your hosting I am sure you can access your data base from cpanel or hosting central of your account download your data base its the most important thing you need becaue wordpress is just a CMS. after downloading data base follow step 1 and load the data base from within wordpress or from hosting center.
the third that is download wordpress and find wp-dependencies.php upload it to appropiate folder might help you keep us up to date what are you doing.
