As an experienced and certified professional in Windows Security & Forensics, Ethical Hacking, Web Application Security, and Website Penetration Testing such as your job entails, I believe I am tailor-made to tackle this persistent malware issue on your Joomla sites. My skills in vulnerability assessment, malware analysis, and server security hardening will be invaluable in securing your website against future attacks and permanently eradicating any existing infections.

This proficiency will serve well in dismantling the highly dynamic and evolving malicious script that keeps infecting your files.
Moreover, my familiarity with your current setup – Joomla with YooTheme template and updated JCE and GDPR extensions –combined with my track record in ensuring PCI & HIPAA compliance in vulnerability assessments adds a layer of significance.
