Detect & Remove Malware From WordPress

Easy Steps To Remove Malware From WordPress Site: 

Once we have realised that our site has been infected with some type of malicious code, the first thing we must do is to detect what type of malware has infected us and which files are the ones that are infected. Also, some useful steps for finding and removing malware from wordpress website. To achieve this goal, we can make use of several options.

1 – Run An Antivirus Scan On Computer

Another option that we can use to detect files that have been infected is to use an antivirus that we have installed on our computer. With an FTP program, we can download the entire site so that each of the files that are part of the web is analyzed in search of malicious code.

Normally the antivirus is able to analyze the files while they are being downloaded, so once the download is completed we should only go to see the generated report to know which are those that have been designated as potentially dangerous.

2 – Run Website Malware Scan Online

If the above options have not yielded good results or you do not like them, we can always use some of the online tools that we can find online and that are able to scan our site for malware. WP Hacked Help is among the most popular site which detects and remove malware from the WordPress.

Once our entire site has been analyzed, WP Hacked Help shows a report with the files that have been infected.

Within the online tools, we can also activate the Google Webmaster tool to consult its  “Security problems” section where it will inform us about the type of threat we are suffering.

3 –  List Files By Modification Date

One of the fastest ways to detect potentially dangerous files is to access via FTP and sort them by modification date. Thus, in the first places will appear those who have suffered some type of change recently.

If we have not changed anything in them, it can be a symptom that inside there is some kind of code that is causing the problem.

The problem with this system is that you should go through all the folders that are part of the site to locate each of the infected files, a job that could be very tedious if the code has been inserted in a large number of files.

4 – Scan your downloads folder

Scan-Wordpress-Database-For-Malware

You must scan the download folder for possible malware. Typically, the download folder does not contain any PHP files. So, delete all PHP files in a wp-content folder.

Now, you may be wondering how to find all the possible PHP files in this folder because the size of your download folder is much larger.

How to find and delete PHP files in a specific folder?

  • Using the cPanel File Manager

You can do this with the cPanel file manager. Type .php in a search bar and select the current directory. The file manager will display all PHP files. 

FileZilla does a great job if you want to filter a specific file type and only want to delete certain types of bulk files. Here’s how to use the FileZilla file filter;

Another way to discover PHP files in the download folder is to use Windows Search. Download the “uploads” folder on the PC and use the Windows Explorer search to list the PHP files.

After cleaning your wp-content folder and reinstalling the theme and plugins, also install a security plug-in named Anti-Malware and Brute-Force Security, then analyze your WordPress with this plugin. This plugin can detect many known threats and traps and correct them. It can also update your obsolete Tim thumb script.

5 – Back up your WordPress site completely and regularly

Before any intervention, make a regular backup of your WordPress site. You must save the following items:

  • Your MySQL database
  • Your FTP account

Your host may have a full backup system directly accessible via cPanel for example. Take the opportunity to get a complete ZIP of your site!

6 – Deactivate Plugins/Clean Up WP Theme

The most likely way that WordPress has hacked is that it’s a plugin or theme and a vulnerability that it had. Or you have downloaded free of charge from unreliable sources.

The step we are now going to take is simple but much more important in order to remove malicious code:

  • We must Scan & Detect Malware in WordPress Themes and make sure we download themes from the original source and replace the files in the folder with the name of the template in /wp-content/themes/ by the newly downloaded. 
  • If you made any changes directly to these files and did not use a child theme, you will lose those changes.
  • If so, you will have learned how important it is to create and what the child theme is for.
  • The next step is to repeat what we have done so far but with the folders that contain the plugins. We will have to download the clean plugins from their respective repositories and replace them.
  • That is, delete the path /wp-content/plugins/ the folder of each of the plugins and copy the new files.

7 – Change Passwords

An important measure that you must take is to change all the passwords that have relation with your web.

  • Change the password of all users with administrator level.
  • Change the access password to your hosting panel.
  • Even if you do not make much use of FTP, change the password.
  • And finally, change the password of the user of the database.

The last two steps you can do from CPanel or from the panel that you from your hosting provider in your case:

  • If you use CPanel you will have to go to the Database section-> MySQL Databases-> Current Users-> Change password.
  • Once you have changed it, it is important that you update it in the wp-config.php because otherwise, the web will not work when not connecting to the database.

Open the file and in this line, change the password:

/** MySQL database password */

define( 'DB_PASSWORD', 'password_here' );

And take the opportunity to review this file looking for any line or text that is suspicious. It may also be the case that it has to modify it.

Use secure password whether on your WordPress site or on your personal computer, must have a password of at least 8 characters including:

  • Numbers ;
  • Special symbols;

This will save you from hacker attacks of testing dictionary words.

  • Avoid any information that refers to your personal life such as a birth date, a department number. Nowadays, privacy is poorly protected on the Internet.
  • Of course, use unique passwords for your different accounts. A password to govern them all and we have seen how it ends.

8 – Find Malicious User

If you are registered and your WordPress website has many users, click here. Some hackers register on your WordPress and execute malicious scripts exploiting any vulnerability of their theme or their plugin. You can use Stop Spammers to spam and delete them.

9 – Remove the default ‘admin’ account

In older versions of WordPress, the admin id was the  administrator account created during installation. It is, therefore, a first-rate identifier tested by hackers during brute force hacking attempts.  (Also Read – How To Change Your WordPress Username)

10 – Lock WP Login To Limit Login Attempts in WordPress

By default, it is possible to test as many login/password pairs as you want to connect to your WordPress administration. Login LockDown records the IP address and timestamp of every failed WordPress login attempt. After a certain number of attempts are detected within a short period of time from same IP range, then the login function is disabled. This helps to prevent brute force password discovery. 

So install the Login Lock Down plugin to restrict the number of attempts allowed for a certain amount of time.
