How I Removed Malware from a WordPress Website in 5 Steps

Malware is like an unwelcome guest that disrupts your system and causes chaos. You know, the type who spills drinks on your carpet and eats all the snacks. As a WordPress security expert, I’ve seen my fair share of these digital party crashers. One particular incident stands out, so let me take you through my journey of how I removed malware from a WordPress website in 5 steps. Get ready, because we’re in for an exciting journey!

5 Steps to Remove Malware from a WordPress Website

Before proceeding with the steps, it’s crucial to create a backup of your website. Make sure to follow Step 2 before making any changes, as this will ensure you have a secure copy in case anything goes wrong during the process.

Step 1: Identifying the Malware

When it comes to identifying malware, think of it like detective work. The first sign of trouble might be weird redirects, a sudden drop in website traffic, or strange ads popping up on your site. To confirm your suspicions, you can use a reliable security plugin like Wordfence or Sucuri. These tools scan your website for malicious code, much like a detective searching for clues. Once the scan is complete, you’ll get a report highlighting infected files or suspicious activity. This step is crucial because you need to know what kind of malware you’re dealing with before you can remove it.

Step 2: Backing Up Everything

Before diving into malware removal, it’s crucial to back up all your site data. By doing this, you can revert your site to its previous condition if any issues come up during the cleanup process. If you’re using a hosting service, they might already provide a backup service. Contact your hosting provider for more details. A comprehensive backup involves two main steps: a. backing up your files and b. backing up your database.

a. Files Backup

There are multiple methods available for backing up your WordPress files. Here are some popular methods:

i. Using a Plugin

Using a backup plugin is one of the simplest methods to back up your WordPress files. UpdraftPlus is a widely used and free option. Here’s how to use it:

  1. Download and activate the UpdraftPlus plugin on your WordPress site.
  2. Navigate to the UpdraftPlus settings and click on the “Backup Now” button.
  3. Store the backup files in a secure location, such as cloud storage or an external hard drive.

ii. Using SSH

For those comfortable with command-line tools, SSH provides a straightforward way to back up your site:

zip -r wp_backup.zip /path-to-your-wordpress-directory

iii. Using SFTP

Another method is using an SFTP client like FileZilla:

  1. Use an SFTP client to establish a connection to your website.
  2. Locate the WordPress directory within your server files.
  3. Drag and drop the entire folder to your local machine to initiate the backup process. This might take some time, depending on your site size and internet speed.

b. Database Backup

Backing up your database is just as important as backing up your files. Here are some common methods:

i. Using a Plugin: Plugins such as UpdraftPlus can also handle backing up your WordPress database:

ii. Using PHPMyAdmin: If PHPMyAdmin is available to you, you can perform a manual backup of your database:

iii. Using SSH: For those who prefer using the command line, you can back up your database via SSH:

mysqldump -p -h your-hostname -u your-username your-database-name > wp_backup.sql

c. Final Steps

Once you have backed up both your files and database, make sure to delete any backup copies from the server to prevent unauthorized access. Store your backups in multiple secure locations, such as cloud storage and external drives, to ensure you have multiple restore points.

With your site fully backed up, you can confidently proceed with the malware removal process, knowing you have a safety net if anything goes wrong.

Step 3: Cleaning Up the Mess

Now that you’ve backed up your site, it’s time to clean up the mess. Wordfence makes it easy to remove malware from your WordPress site. Follow these steps to get started:

i. Removing Infected Plugins and Themes

  1. Identify Infected Files: Wordfence will scan your site and provide a report of infected files, including plugins and themes.
  2. Delete Infected Plugins: Navigate to the wp-content/plugins/ directory and delete any infected plugins. This can be done through your hosting file manager or via an SFTP client.
  3. Delete Infected Themes: Similarly, go to the wp-content/themes/ directory and remove any infected themes and their child themes.
  4. Reinstall Clean Versions: After deleting the infected plugins and themes, reinstall the original, clean versions from reputable sources. Avoid using nulled themes or plugins because they frequently contain malware. Stick to those with a good reputation and regular updates from the developer.

ii. Cleaning WordPress Files

Malware can be hidden in various WordPress files, making it challenging to identify and remove. Wordfence simplifies this by flagging suspicious code. Here’s how to proceed:

  1. Scan with Wordfence: Run a full scan with Wordfence to identify infected files.
  2. Review and Clean: Carefully review the flagged files. If you’re unsure whether a piece of code is malicious, consult the Wordfence documentation or seek help from the WordPress community.
  3. Update Everything: Ensure all your plugins, themes, and WordPress core files are updated to the latest versions. Using outdated software increases the risk of malware infections.

iii. Cleaning Up the Sitemap

The sitemap.xml file often gets overlooked but can also be compromised. Here’s how to clean it:

  1. Locate the Sitemap: The sitemap is usually located in the root directory, such as www.example.com/sitemap.xml.
  2. Remove Suspicious Entries: Open the sitemap file and delete any suspicious links or spammy characters you find.

iv. Cleaning the Database

Malware can also infect your database, and cleaning it requires a bit more technical know-how. If you have access to phpMyAdmin or the MySQL console, follow these steps:

UPDATE wp_posts SET post_content = REGEXP_REPLACE(post_content, '<script>.*', '');

For more complex cases, you’ll need to adjust the query accordingly.

Final Steps

With the malware removed, make sure to re-scan your site with Wordfence to ensure all traces are gone. It’s also a good idea to set up regular scans and monitoring to catch any future threats early.

Step 4: Strengthening the Fort

With the malware removed, it’s time to fortify your website. Begin by changing all passwords—administrative accounts, databases, FTP, and any others. Make sure every account has a strong, unique password.

Next, install a security plugin to act as your website’s bodyguard. Plugins like Wordfence or Sucuri offer real-time protection, firewall features, and regular scans. Moreover, enables two-factor authentication (2FA) to provide an additional layer of security. It’s like adding multiple locks to your front door, making it harder for intruders to get in.

Step 5: Monitoring and Maintenance

The final step is to keep an eye on your website. Set up regular scans and monitoring to catch any future threats early. Plugins like Sucuri and Wordfence can be configured to send you alerts if something suspicious is detected. Regularly update your WordPress core, themes, and plugins to address any security vulnerabilities. Think of this step as regular check-ups for your website — prevention is better than cure.
