How to Remove Malware From a WordPress Website

Copy Link

A WordPress website can become infected with malware without any obvious warning. You might notice slow loading speeds, strange pop-ups, unexpected redirects, or even a warning from Google that your website may be unsafe. These issues can damage your reputation, reduce search engine rankings, and put customer data at risk.

The good news is that malware can be removed, and with the right maintenance strategy, future attacks can often be prevented. Investing in professional wordpress maintenance and support services can help website owners detect security issues early, keep software updated, and maintain a secure online presence.

In this guide, you'll learn how malware infects WordPress websites, how to remove it safely, and what you can do to prevent future infections.

What Is WordPress Malware?

Malware is malicious software designed to gain unauthorized access to your website or damage its functionality. Cybercriminals use malware for many purposes, including:

Stealing customer information
Sending spam emails
Redirecting visitors to harmful websites
Injecting unwanted advertisements
Mining cryptocurrency
Creating hidden backdoors for future attacks

Because WordPress powers millions of websites, it is a frequent target for automated attacks.

Common Signs Your WordPress Website Has Malware

Not every malware infection is immediately visible. However, several warning signs indicate your website may be compromised.

Unexpected Redirects

Visitors are automatically redirected to suspicious or unrelated websites.

Google Security Warnings

Search engines may display messages such as:

"This site may be hacked."

"Deceptive site ahead."

Slow Website Performance

Malicious scripts often consume server resources, making pages load much slower than normal.

Unknown Files

New files suddenly appear inside your WordPress installation.

New Administrator Accounts

Hackers sometimes create hidden administrator accounts to maintain access.

Spam Content

You may discover spam pages, hidden links, or strange keywords appearing throughout your website.

Step 1: Put Your Website Into Maintenance Mode

Before making changes, temporarily prevent visitors from accessing the infected website.

This helps:

Protect users from malicious content
Prevent search engines from indexing infected pages
Allow safe cleanup

Many maintenance plugins make this process simple.

Step 2: Create a Complete Backup

Although your website is infected, always create a backup before removing malware.

Back up:

Website files
Database
Media uploads
Themes
Plugins

A backup allows recovery if something goes wrong during cleanup.

Step 3: Scan the Website

Run a comprehensive malware scan using a trusted security scanner.

The scan helps identify:

Infected files
Suspicious code
Hidden backdoors
Modified WordPress core files
Vulnerable plugins

Review scan results carefully before deleting any files.

Step 4: Remove Malware From Infected Files

After identifying infected files, remove malicious code carefully.

Common infected locations include:

wp-content
uploads folder
theme files
plugin files
wp-config.php
.htaccess

Avoid deleting files unless you're certain they're malicious.

When possible:

Replace infected WordPress core files with fresh copies.
Replace compromised plugins from official sources.
Reinstall themes if necessary.

Step 5: Remove Unknown Users

Delete:

Unknown administrators
Suspicious editors
Accounts you didn't create

Then:

Reset passwords
Enable strong passwords
Change administrator usernames if needed

Step 6: Update Everything

Outdated software is one of the biggest reasons WordPress websites become infected.

Always update:

WordPress core
Themes
Plugins
PHP version

Updates often include security patches that close vulnerabilities before hackers exploit them.

Step 7: Change All Passwords

After malware removal, change every password associated with the website.

This includes:

WordPress admin
Hosting account
FTP
SSH
Database
Email accounts

Use strong, unique passwords for every account.

Step 8: Remove Unknown Plugins and Themes

Inactive plugins and themes can still contain vulnerabilities.

Delete anything you no longer use.

Only install themes and plugins from trusted developers.

Avoid downloading:

Pirated themes
Nulled plugins
Modified premium software

These are among the most common sources of malware.

Step 9: Check File Permissions

Incorrect file permissions make it easier for attackers to modify website files.

Generally recommended permissions include:

Files: 644
Folders: 755

Sensitive files should have even stricter permissions where appropriate.

Step 10: Secure wp-config.php

The wp-config.php file contains important website configuration details.

Protect it by:

Moving it outside the public directory when supported
Restricting file permissions
Blocking unauthorized access

This simple step improves website security significantly.

Step 11: Inspect the Database

Hackers sometimes inject malicious code directly into the database.

Look for:

Spam posts
Unknown users
Hidden links
Suspicious scripts
Modified options

Clean any malicious entries before restoring normal website operation.

Step 12: Request Google Review

If Google flagged your website, request a security review after cleanup.

Before requesting:

Verify malware removal
Confirm all vulnerabilities are fixed
Run another security scan

Google usually reviews websites within a few days.

How Malware Infects WordPress Websites

Understanding common infection methods helps prevent future attacks.

Weak Passwords

Simple passwords are easy targets for brute-force attacks.

Outdated Plugins

Old plugins frequently contain publicly known vulnerabilities.

Outdated Themes

Hackers regularly scan the internet for websites using vulnerable themes.

Insecure Hosting

Poor server security can expose multiple websites at once.

Nulled Software

Free versions of premium plugins often include hidden malware.

File Upload Vulnerabilities

Improperly secured forms may allow attackers to upload malicious files.

Preventing Future Malware Infections

Removing malware is only half the job.

Long-term prevention is equally important.

Install a Security Plugin

Security plugins can:

Scan files
Block malicious traffic
Detect login attempts
Monitor file changes

Regular scanning catches problems before they become serious.

Enable Two-Factor Authentication

Two-factor authentication adds another security layer beyond passwords.

Even if someone steals your password, they still need the second verification step.

Schedule Automatic Backups

Daily or weekly backups ensure you can quickly recover from security incidents.

Store backups:

Off-site
Cloud storage
Separate servers

Never keep only one backup.

Limit Login Attempts

Unlimited login attempts make brute-force attacks easier.

Limiting failed logins greatly improves security.

Use SSL

HTTPS encrypts communication between visitors and your website.

SSL certificates also improve trust and search engine rankings.

Monitor Website Activity

Activity logs help identify:

Unauthorized logins
File changes
Plugin installations
User account modifications

Early detection often prevents major security incidents.

Why Professional WordPress Maintenance Matters

Many website owners only think about security after malware appears.

Regular maintenance helps prevent infections before they happen.

Professional maintenance teams typically perform:

Security monitoring
Malware scanning
Plugin updates
Theme updates
Performance optimization
Daily backups
Uptime monitoring
Database optimization

Instead of reacting to problems, they focus on preventing them.

For businesses that rely on their websites, proactive maintenance saves time, money, and reputation.

Conclusion

Malware can seriously disrupt a WordPress website, affecting performance, search visibility, customer trust, and overall business operations. Fortunately, careful cleanup combined with strong security practices can restore your website and significantly reduce the risk of future infections.

Keeping WordPress updated, using trusted plugins, maintaining secure passwords, and monitoring website activity are essential habits for every website owner. For ongoing protection, many businesses choose professional wordpress maintenance and support services to handle updates, backups, malware prevention, and continuous security monitoring, allowing them to focus on growing their business with confidence.
