Removing malware from a WordPress website involves several steps. Here's a detailed guide to help you clean up your site:
1. Identify the Malware
Scan Your Website
👉Online Scanners: Use tools like Sucuri SiteCheck, VirusTotal, or Wordfence to scan your website for malware.
👉Hosting Provider: Some hosting providers offer malware scanning and removal tools.
2. Backup Your Website
----------
Before making any changes, back up your website files and database. This ensures you have a restore point if anything goes wrong.
Backup Methods
👉Plugins: Use plugins like UpdraftPlus or BackWPup.
👉Hosting Control Panel: Many hosts provide backup options through their control panels.
👉Manual Backup: Download your entire website directory and export your database using phpMyAdmin.
3. Put Your Website in Maintenance Mode
---------------
Inform your visitors that the site is undergoing maintenance. Use a plugin like WP Maintenance Mode to display a maintenance page.
4. Update WordPress, Themes, and Plugins
----------
Ensure your WordPress core, themes, and plugins are up-to-date. This patches known vulnerabilities that malware could exploit.
5. Clean the Infected Files

Manual Cleaning
👉Access Files: Use an FTP client (like FileZilla) or your hosting file manager.

Malware can also infect your database.
