WordPress is one of the most popular content management systems (CMS) in the world, powering over 40% of all websites. However, its popularity also makes it a prime target for hackers. If your WordPress site has been hacked or infected with a virus, it’s crucial to act quickly to restore its security and functionality. In this detailed guide, we’ll walk you through the steps to clean a virus from your WordPress site and ensure it’s protected from future attacks.
Why Do WordPress Sites Get Hacked?
Before diving into the cleaning process, it’s important to understand how WordPress sites get hacked in the first place. Common reasons include:
-
Using Nulled Plugins and Themes: Nulled (pirated) plugins and themes often contain malicious code that can compromise your site.
-
Weak Passwords: Easy-to-guess passwords make it simple for hackers to gain access to your site.
-
Security Vulnerabilities: Even free and original plugins or themes can have security flaws that hackers exploit.
-
Outdated Software: Failing to update WordPress core, plugins, or themes can leave your site vulnerable to attacks.
If your site has been hacked, it’s important to note that most hosting companies do not take responsibility for cleaning it. While some companies may offer this service, they often charge hundreds of dollars per site. However, if you have a basic understanding of how WordPress works, you can clean your site yourself by following the steps below.
Step-by-Step Guide to Clean a Virus from Your WordPress Site
Step 1: Access Your Site’s Folder/Document Root
-
Log in to your hosting account and navigate to the file manager or use an FTP client like FileZilla.
-
Locate the document root of your site. For the main domain, this is usually the
public_html
folder. For addon domains, there will be separate folders.
Step 2: Backup Your Site
Before making any changes, create a backup of your site. This includes:
-
Downloading all files from your site’s directory.
-
Exporting your database using phpMyAdmin or a similar tool.
Step 3: Delete Unnecessary Files
-
In your site’s root folder, keep the following:
-
wp-content
folder (contains themes, plugins, and uploads). -
wp-config.php
file (contains database credentials).
-
-
Delete everything else in the root folder.
-
Open the
wp-config.php
file and copy the database name, username, password, and table prefix. Once copied, delete this file as well.
Step 4: Reinstall WordPress
-
Download the latest version of WordPress from wordpress.org.
-
Upload the downloaded ZIP file to your site’s root folder and extract it.
-
Move the contents of the extracted
wordpress
folder to the root directory.
Step 5: Reconfigure WordPress
-
Open your site in a browser. You’ll see the WordPress installation page.
-
Enter the database name, username, password, and table prefix that you copied earlier.
-
Complete the installation process.
Step 6: Update Permalinks
-
Log in to your WordPress dashboard.
-
Navigate to Settings > Permalinks and click the Save Changes button. This will regenerate your site’s permalink structure.
Step 7: Scan and Clean Your Site with Wordfence
-
Install the Wordfence Security plugin from the WordPress repository.
-
Run a full scan of your site using Wordfence.
-
After the scan, click the following buttons:
-
Delete All Deletable Files

Repair All Repairable Files
-
-
Repeat the scan until no file changes or malware are detected.
Additional Tips to Secure Your WordPress Site

Install a Security Plugin: Plugins like Wordfence, Sucuri, or iThemes Security can help protect your site from future attacks.
