  • Unexpected redirects
  • Google Safe Browsing warning
  • Spam pages indexed in Google
  • Slow website performance
  • Unknown administrator accounts
  • Modified WordPress files
  • Hosting suspension
  • Suspicious scheduled tasks
  • Large increase in server resource usage
  • Website displaying pharmaceutical or gambling content

Immediate Steps Before Malware Removal

Before cleaning your website, perform these important tasks.

Put the website into maintenance mode to protect visitors.

Create a complete backup of both files and the database. Even infected backups can help recover missing content if necessary.

Change all passwords, including:

  • WordPress admin
  • Hosting account
  • FTP
  • SSH
  • Database
  • Control panel
  • Email accounts

Enable two-factor authentication wherever possible.

Scan the Website for Malware

Start by identifying infected files.

Useful malware scanning tools include:

  • Wordfence Security
  • Sucuri Scanner
  • MalCare
  • Solid Security (formerly iThemes Security)
  • VirusTotal (for suspicious files)
  • Hosting malware scanners

These tools help locate infected files, modified scripts, suspicious plugins, and hidden malware.

Remove Suspicious Plugins and Themes

Attackers often exploit vulnerable or nulled plugins.

Check for:

  • Inactive unknown plugins
  • Pirated premium themes
  • Unused plugins
  • Plugins installed without your knowledge

Delete any suspicious files immediately.

Always download plugins and themes from trusted developers or the official WordPress repository.

Replace Core WordPress Files

Core WordPress files should never be modified.

Download the latest version of WordPress and replace:

  • wp-admin
  • wp-includes

Avoid overwriting:

  • wp-content
  • wp-config.php

Replacing core files removes many common malware injections.

Inspect wp-config.php

Open wp-config.php and look for:

  • Obfuscated PHP code
  • Base64 encoded strings
  • eval() functions
  • gzuncompress()
  • str_rot13()
  • Long unreadable variables

Only keep legitimate WordPress configuration settings.

Check the .htaccess File

Hackers frequently modify .htaccess.

Look for:

  • Redirect rules
  • Suspicious RewriteRules
  • Unknown PHP execution rules
  • External redirects

Restore the default WordPress .htaccess file if necessary.

Inspect Uploads Folder

Attackers commonly hide malware inside:

/wp-content/uploads/

Look for:

  • PHP files
  • Executable scripts
  • Randomly named folders
  • Recently modified files

Normally, the uploads folder should mainly contain images, PDFs, videos, and media files.

Clean the Database

Malicious code may also exist inside the database.

Check:

  • wp_posts
  • wp_options
  • wp_users
  • wp_usermeta

Look for:

  • Hidden administrator accounts
  • Spam posts
  • Injected JavaScript
  • iframe tags
  • Malicious links
  • Encoded content

Delete unwanted entries carefully.

Search for Dangerous PHP Functions

Search the website for suspicious functions including:

eval(
base64_decode(
gzinflate(
shell_exec(
system(
assert(
preg_replace(
create_function(
str_rot13(

Although some legitimate plugins may use certain functions, they should always be reviewed carefully.

Check Recently Modified Files

Sorting files by modification date often reveals malware.

Review files modified shortly before:

  • Website problems started
  • Google warnings appeared
  • Suspicious redirects began

Unknown recently modified files deserve careful inspection.

Remove Unauthorized Users

Visit:

Users → All Users

Delete:

  • Unknown administrators
  • Fake editors
  • Suspicious subscribers created in bulk

Verify all administrator accounts belong to trusted users.

Update Everything

After cleaning:

  • Update WordPress
  • Update plugins
  • Update themes
  • Update PHP
  • Remove unused software

Running outdated software is one of the biggest reasons websites become infected.

Reset File Permissions

Recommended permissions:

  • Folders: 755
  • Files: 644
  • wp-config.php: 600 or 640 (depending on hosting)

Avoid giving files 777 permissions.

Install a Security Plugin

A security plugin provides continuous protection.

Recommended features include:

  • Malware scanning
  • Firewall
  • Login protection
  • File change detection
  • Country blocking
  • Rate limiting
  • Two-factor authentication

Request Google Review

If your website was blacklisted:

  1. Clean all malware.
  2. Verify ownership in Google Search Console.
  3. Request a Security Review.
  4. Wait for Google to remove warnings after verification.
