What do you do With the Malware you Found?

First and foremost, it is upsetting to find malicious codes on your site, but now that you have found it, the question that arises is how do you deal with it? You could and must do a few things to clean your website and return it to a clean state.

Change your Passwords

You might have no clue as to how the malware entered your site and the reason behind it affecting your site, but the first step is to reset user passwords.

It could be possible that your passwords had been compromised; therefore, changing the passwords could be a great way of preventing the suspicious event from occurring. Ensure that you use an appropriate plugin to do so.

Clean All the Hacked Files

If your core files are infected, you could fix it manually; ensure that you have a complete backup for all of them. You can replace the custom files with recent backups later.

These simple steps could help you get done with the process quickly.

  • Log in to the server through SFTP/SSH and create a backup for your website first.
  • Select the recently changed files and confirm the dates with the user who made the changes.
  • Restore the suspicious files.
  • For the custom files, open anyone containing a text editor and delete all the suspicious codes you find in those custom files.
  • Lastly, run a test to see whether the site is operating correctly after making these changes.

Audit the Registered Users

It is always better to be on the safer side. So, it is advisable to double-check the users who are having permission for file editing on your website.

If an attacker gained access to your site and created their own user, they will be subjected to the password changes as well.

So you must root such users out and delete them from the database.

Clean Database Tables

If your database tables are hacked, you would have to clean and sort them out as well. To remove the malware from your database manually, you will have to follow a few simple steps.

Firstly, login into the database admin panel and create a backup. This step is essential before you make any changes to your actual database. Next, look for any questionable WP content folder that you find.

Once you have found the content, open the table and manually remove all the questionable content. And lastly, run a test to check whether your website operates appropriately after making the changes.

Secure User Accounts

If you wish to keep your website safe and free from any hacking, it is recommended to have a single admin user and set other user roles to the bare minimum of rights required for the work that is needed to be done by that user.

If you find certain unfamiliar user accounts on your WordPress website, you must instantly remove them. Here’s the process through which you could manually remove such user accounts.

  • As mentioned earlier, the primary step to any process is creating a backup.
  • Enter your WordPress site as the admin and click on “users.”
  • Look for unfamiliar WordPress user accounts and then delete them.


This is a new way of avoiding any hacker from entering your website and getting full access to it. If you wish to utilize this benefit, then ensure that your website has two-factor authentication (2FA).

Through this step, even if your password gets compromised, there is no way the attacker could go further into your site and misuse it. Nowadays, this measure has been adopted by many users to secure their WordPress sites from threats.

Get Rid of the Backdoors on your Site

One of the most common things that hackers do is leaving backdoors, i.e., paths through which they could enter back on your site. Several backdoors are present on the site at times, and the user is entirely unaware of it.

They are often embedded in files, and these files look similar to the WordPress core files. Therefore, if your find files with PHP function like exec, system, base64, etc. located within the wrong directories; go ahead and delete them as they could be malicious files.

It is essential to stop all these backdoors as soon as possible, or else there could be chances of your website getting infected quite easily.
