since few days my website having backdoors i my webs few pages are hacked www.pakistani.pk/songs check this how i could i get rid of these hackers?
You can get the webserver logs and look which links were accessed during the attack, the backdoors are usually hidden inside the code of your site... after you locate the accessed scripts you need to manually look trough them all and remove the backdoor code... Good Luck.
How do you know you have backdoors? Have you found any of the shell scripts? Do you know how the hackers gained access to your site?
the script which you are using is very buggy,and anyone who knows little bit about hacking can hack you
Sounds like phpSiteScanner might be helpful. It is designed to find code that contains the type of commands that hackers use in shell scripts, uploaders, etc.
