server manager says:

...I have installed AVG Malware scanner for linux and not able to detect any vulnerable files.Please understand that it is not the hacker/attacker who inserted the codes. The developer "coding style" is vulnerable. When we go for cheap plugins or themes, we are not caring for coding style that is causing such vulnerabilities. The vulnerability means that it is open to such website cross scripting or some other type of attacks...

But my problem is I have disconnected with the developer from 4 years ago and I don`t know what I must do to fix the bad codes...
