How to Fix Malware on a WordPress Website

Discovering malware on your WordPress website can be stressful. Malware can infect your files, steal sensitive data, damage SEO rankings, and even make your website unusable. If left untreated, it can harm your business, visitors, and reputation.

In this guide, we’ll explain what malware is, how it infects WordPress sites, and provide step-by-step instructions to clean your site and protect it in the future.

What is WordPress Malware?

Malware is malicious software designed to harm your website or steal data. In WordPress, common types include:

Backdoors – Hidden scripts allowing hackers to regain access.
SEO Spam – Injected spam content or links that hurt your rankings.
Redirects – Malware that sends visitors to malicious websites.
Phishing Scripts – Collect user credentials or sensitive data.
Ransomware – Locks your website files until a ransom is paid.

Common Signs of Malware on WordPress

Detecting malware early can save your site. Look out for:

Your website is slow or unresponsive.
Visitors report redirects to unknown websites.
Search engines flag your site as unsafe or hacked.
Suspicious files appear in your WordPress installation.
Unexpected user accounts or changes in plugins/themes.
Emails sent from your site without your knowledge.

Step 1: Backup Your Website Immediately

Before cleaning malware, create a backup:

Use an FTP client or hosting file manager to download all WordPress files.
Export your database via phpMyAdmin.
Store backups offline to ensure they remain uninfected.

This step prevents permanent data loss during malware removal.

Step 2: Put Your Site in Maintenance Mode

Temporarily restrict public access using a maintenance plugin or server configuration.
This prevents further infections and stops visitors from encountering malicious content.

Step 3: Scan Your Website for Malware

Use trusted security tools to detect malware:

Wordfence Security: Free and paid versions scan files for infections.
Sucuri SiteCheck: Online scanner that checks for malware, blacklisting, and vulnerabilities.
MalCare: Detects hidden malware and malicious code.

Tip: Don’t rely on just one scanner; using multiple tools ensures thorough detection.

Step 4: Remove Malware Manually

If malware is detected, you can clean it manually:

Delete suspicious plugins and themes: Remove unused or unknown plugins/themes.
Check wp-config.php and .htaccess: Look for unfamiliar code or scripts.
Scan PHP files: Malware often hides in files with strange names or code snippets.
Replace core files: Download a fresh copy of WordPress and overwrite core files (except wp-content).

Warning: Manual cleaning requires caution—mistakes can break your website.

Step 5: Use Malware Removal Plugins

For safer cleaning, consider professional WordPress security plugins:

Wordfence Premium: Offers malware removal and firewall protection.
Sucuri Security: Paid service provides full malware cleanup and hardening.
MalCare Premium: One-click malware removal and ongoing monitoring.

These tools automate the cleaning process and reduce human error.

Step 6: Change All Passwords

After cleaning:

Update your WordPress admin passwords.
Update database passwords in wp-config.php.
Change FTP/SFTP and hosting account credentials.
Ask users with admin access to update their passwords.

Step 7: Update WordPress, Plugins, and Themes

Outdated software is a common entry point for malware.
Ensure WordPress core, plugins, and themes are up-to-date.
Remove any plugins or themes you are not actively using.

Step 8: Harden WordPress Security

Prevent future infections with these measures:

Enable a firewall: Use Wordfence or Sucuri to block malicious traffic.
Limit login attempts: Protect against brute-force attacks.
Use strong passwords and 2FA: Reduce the risk of unauthorized access.
Regular backups: Automate backups using UpdraftPlus or BackupBuddy.
Disable file editing: Add to wp-config.php:

Secure permissions: Set correct file permissions (typically 755 for folders and 644 for files).

Step 9: Monitor Your Website

After cleaning:

Regularly scan your website for malware.
Enable email notifications for suspicious activity.
Check Google Search Console for warnings.

Early detection prevents small infections from becoming major issues.

Step 10: Consider Professional Help

If malware persists:

Hire a WordPress security expert.
Services like Sucuri and MalCare offer full removal and hardening.
Professional cleaning can save time and ensure your website is fully secure.
