Hi there,
I have 9+ years of experience in PHP, WordPress and Internet security with 500 reviews on Freelancer.
I have worked on similar malware cleanup projects earlier, please check my recently completed projects
I can remove the existing phishing pages and malware/virus 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 and access to your hosting. I will also transfer the site to your new hosting after the site is cleaned.
.
I will make sure that there are no backdoors left over. I have been familiar with the malware you listed
I will also update WP and its plugins to the latest version and harden WordPress
Looking forward to work for you. Lets get this done.
Best Regards,
Syed
