If you own a WordPress website, it’s essential to make sure that it’s well-secured. A vulnerable site will become an easy target for cybercriminals. They can harm your website in many ways, such as infecting it with malware.
Malware can’t be taken lightly as it continues to develop and increase each year. You can take preventive measures from this problem, like updating your site regularly, for instance.
Other than that, you should also equip yourself with WordPress and web-related insights to help you know what’s right for your site. There are plenty of articles and knowledge bases to learn from on the internet, such as HostingWiki.
However, if your website is already infected, don’t panic just yet. This article will explain what malware is, how you can remove it from your site, and prevent future attacks.
What is Malware and Why is It Dangerous?
Malware stands for Malicious Software. As the name implies, it’s a piece of software that is intended to cause harmful effects, such as stealing information or damaging a website.
It takes on many forms, and each can cause a specific problem. Here are several common types of malware that you should look out for:
- Adware – automatically shows unwanted advertising materials on your site.
- Spyware – steals sensitive information by gathering data discreetly.
- Trojans – disguises as real software to trick people into executing a dangerous program. In some cases, it might change your site’s appearance and content spontaneously.
- Virus – contains malicious code to corrupt files and replicates itself across a site. It usually comes with a sudden rise in server consumption.
- Ransomware – locks a site until someone paid a specified amount of money.
If your site has one of the symptoms mentioned above, it might be a sign that you are experiencing a malware attack.
Furthermore, it can harm your website’s SEO (Search Engine Optimization) ranking. Google will show a warning message on sites that are considered harmful – including the ones that are infected by malware.
That’s why protecting your WordPress website from malware infection should be nothing less than a priority. It’s also important to know how to remove it, which will be covered next!

Perform a Site Backup
It’s essential to back up your files before making any changes so you won’t lose any data if the process doesn’t go as planned. There are several ways to do it.
You can start with your hosting provider. Some providers offer an automatic backup feature, which can be scheduled to daily or monthly based on your hosting plan. Or, you can export the site through a backup plugin.
However, if you lose access to your dashboard, you can try the manual backup through phpMyAdmin. You just need to log in to your hosting panel, then enter your phpMyAdmin dashboard.
Afterward, you can proceed by choosing your database, and click on the Export tab.
Now you can choose the quick option or the custom option. If you want to get a better view of all the data that will be exported, you can pick the custom one. Then, phpMyAdmin will send you the exported database in a .zip file.
Do Some Scanning
When you’re done backing up your data, you can start scanning your site. As a starter, use an anti-malware program – such as Malwarebytes to prevent the malware from spreading to your computer. Scan the exported database as well to make sure that it’s free from the infection.
Aside from scanning your computer, you should scan your website using a site security checker like Virus Total or Quttera. These tools will show you which security issues that your website is facing. It’ll also tell you whether search engines have blacklist your site due to malware.
The tools will also give you some suggestions to increase your site’s security. For example, installing a cloud-based WAF (Web Application Firewall) if your site is vulnerable to website hacks and DDoS attacks.
Change The Passwords of Your Hosting Panel and FTP
It’s essential to change the passwords of your hosting panel and FTP account to prevent malware from taking over your database.
If you’re using cPanel, you can change the account’s password on the Preferences section. Then go to the Files section to find your FTP account and reset the password there as well.
To make things more secure, you can also change the MySQL password by entering the Database section in your panel. Don’t forget to update the password in the wp-config.php file – by using an FTP client like FileZilla. Otherwise, you won’t be able to connect the database.
Make sure that the updated passwords contain more than eight words, numbers and special characters – such as exclamation mark (!) or ampersand (&). Then, save it somewhere safe just in case you forget it.
Eliminate Malware Infected Files
This is the most crucial part since you have to remove all the infected files thoroughly. To do that, you should enter the File Manager in your control panel. Then, click on the public_html folder, which contains WordPress installation files.
You will see plenty of files and folders. To check which files that are potentially harmful, you can sort them based on the modification date. If the files show unwanted changes, it might indicate that they have been infected.
To clean the core files, you need to delete everything within the public_html folder. However, you must leave the wp-config.php file and wp-content folder untouched since we’ll deal with them later.
It’s because the wp-config.php file contains essential information, such as the username and password of your WordPress database. The wp-content folder, however, consists of three essential folders: themes, plugins, and uploads.
Now, let’s clean up the wp-config.php file. Open both the file and wp-config-sample.php at the same time. Compare them, and remove any differences by making sure that the wp-config.php file is free from unwanted codes.
Next, you can fix the wp-content folder. First, check the plugins folder, list all the plugins that you’ve installed, then delete the folder. Then, do the same with the theme folder. Don’t forget to remove the index.php file as well.
Last but not least, you should open the uploads folder and delete all the .php files in it. If there are any unusual files in the folder, you can remove them too.
Download and Install the Latest Version of WordPress
After cleaning your website, you can restore the infected files by installing a brand new WordPress. If your hosting provider has a one-click installer feature, you can install it right from the control panel.
When you’re required to create an admin password, it should be different from your previous one. Do make it harder to guess as well, such as adding numbers and special characters.
Re-Install Themes and Plugins
Remember that you’ve deleted the themes and plugins folder? Now is the time to get them back. You can install them one by one by referring to the list you’ve made.
Never upload your old themes and plugins from the exported database – unless you’re totally sure that it’s free from malware. You can use them as a reference to build your customized theme from scratch.
Restore Public Access
Now that your website is finally clean, you can make it open to the public. If you’re using a plugin for showing the maintenance mode page, simply go to the admin dashboard and disable it.
However, it might not be available to the public right away. You can check whether your hosting provider is blocking access to your site. If they are, you can request them to re-scan your website and restore its access afterward.
Show Google that You’re Not Infected
Last but not least, it’s important to remove the warning label from your site so Google can index your website in the search results page.
There are some steps you need to do to recover your site in Google:
- Open Google Search Console
- Add your website
- Open the Security Issues Report, and select Request a Review
- When submitting the review, don’t forget to mention what you did to remove policy violation on your site
- Once the review is done, you’ll get a notification about the result in your email
