Cleaning Infected Files in WordPress Step by Step

WordPress is the most popular website platform - which also makes it a frequent target of malicious attacks. When a site is infected by malware it may show suspicious messages, redirect visitors to unknown pages, or even get de-listed by search engines. Cleaning infected files is a critical task that should be done immediately.

1. Create a full backup
Before doing anything else, create a complete backup of the site and database. Even if it’s infected, it provides a reference point.

2. Inspect files and folders
Next, review the WordPress directories (wp-content, themes, plugins) for suspicious files that don’t belong to the original code. Malware often hides in oddly named files or modified core files.

3. Replace core and plugins
The safest approach is to replace WordPress files with a clean installation of the latest version. Do the same for plugins and themes, and only use trusted sources.

4. Clean the database
Malware frequently injects malicious content into the database. Inspect tables for suspicious scripts, links or spam content and remove them carefully.

5. Review users and privileges
Creating rogue admin accounts is a common tactic. Check active users and remove any you don’t recognize.

6. Harden security
After cleanup, it’s essential to harden the site:
1. Change all passwords
2. Install security plugins
3. Keep everything updated and monitor files
