Hi there,
I have 9+ years of experience in PHP, Joomla and Linux.
I have worked on similar malware cleanup projects earlier including server security and hardening,
I can remove the existing malware from your website and restore it and make sure that it doesn't happen again, finding out the reason.
Please also provide me with the website URL.
Looking forward to work for you. Lets get this done.
Best Regards,
Syed
