New Administrators in my forum

[elfenny]

Hello, my problem is this ... Days ago appeared a new user as administrator Th3H4ck, then actualize to 4.2.1 to solve the problem, a few days my forum was hacked but did not affect database. Hack files:
/ home / **** / public_html / injector.php {PYX}. php.obfuscated-exec.crit
/ home / **** / public_html / DBTech / database.php {HEX}. php.nested.base64.513
/ home / **** / public_html / DBTech / cp.php {PYX}. php.eval.post.crit.1
/ home / **** / public_html / cgi-bin / lsos.php Injected: {HEX}. gzbase64.inject.unclassed.18
+ / home / **** / public_html / lsos.php Injected: {HEX}. gzbase64.inject.unclassed.18

+ Then there have been 2 new users without visible changes in the forum. As I can stop these administrators?
I went to Admin Panel> Statistics and Records> Registration Control Panel and see something strange, if I can explain about these changes ...
