I am working on project on localhost (not live yet) which is built in php using codeigniter framework, recently it start showing warning message which might due to malicious code injected in website, I tried all solution like checked my index.php, .htaccess and other plugins but nothing worked for me, I have followed some blogs also how to remove malware from site but that also didn't work, so my question is how to figure out in which file, in which line malicious code is injected and how to remove using any plugin or offline tool.
some links which I followed:
