Hi @slowhost
It sounds like you have a malware infection on your WordPress website that keeps coming back, even after removing it and taking other measures to secure your site. This can be a very frustrating and time-consuming problem to deal with. To help you resolve the issue, here are a few steps you can take:
1. Back Up Your Website: Before making any changes, creating a backup of your website is essential. This will allow you to restore your site to its previous state if something goes wrong.
2. Check for Malicious Code: Look for any suspicious or malicious code in your WordPress files, particularly in the theme and plugin files. You can use a tool like Hex to Hex Viewer to examine your files for any unusual code.
3. Change All Passwords: Make sure to change all passwords associated with your website, including your WordPress admin password and FTP login credentials. Use strong, unique passwords, and consider using a password manager to help you generate and store them securely.
4. Re-Upload Core Files: You can try re-uploading the core WordPress files. This will replace any compromised files with fresh copies. However, please back up your website before doing this, as it may cause some customizations to be lost.
If you have tried these steps and the malware keeps returning, the infection may be more deeply rooted and require more advanced measures to remove. In this case, you may consider hiring a professional to help clean up your site.
