If you see security warnings when trying to reach your website, the first thing to do is identify the type of warning. This warning message on your site is the key to understand what Google is telling you about the type the security issues on your site. The specific message depends on the virus or browser you are using. The right column lists all the types of warning messages that can appear on your site.

Review Diagnostic Pages

Every warning message on your browser will link to another page that describes why the website has been blacklisted by Google. The main button on the page  is for user visitors with messages like Get me out of here, but usually there is a link for the website, blog or e-commerce owner.

So, what you must do is:

  1. Visit the Google Transparency Report
  2. Enter your website URL
  3. Review the Site Safety Details and Testing Details

You find important info in the report, as malicious content is being detected on your site. And you will need these URLs when you remove the malware from your site.

In addition, some malicious domains that are on your site could be a hidden iframe, external script, or unauthorized redirect. Note these domain names to scan for them in the following section. The important things to look for are:

  • Scan date: how recently Google scanned your site
  • Discovery date: when the suspicious content was originally detected

 Scan your site or sites

Now is time to find any malicious payloads, security issues, malware locations, and blacklist status with major authorities. If you have more than website on your server, scan them all.

Using any of WeSecur’s plans you scan automatically your site so you will already have this info. Although if you don’t have any security maintenance you use any free website scanner as virustotal.

Remove File Infections

To remove malware from your site you should be edit files on your server. If you are not comfortable with this, ask for professional help. First of all, you must backup your website.


You can replace infected files if you use a CMS such as WordPress or Joomla. You can use copies of your core files and extensions directly from the official repositories. And with fresh non infected backup copies, you can replace custom files.

Malicious Domains

If the Diagnostic Page indicates any malicious domain or payload, then you can start looking for those files on your server.

Hackers change malicious sites to avoid detection. So, maybe you can not found on your site as they have already been replaced with other domains.

How to Remove a Malware Infection from your Website files

  1. Log into your server via SFTP or SSH.
  2. Create a backup of the site.
  3. Search your files for any reference to malicious domains or payloads.
  4. Identify suspicious or recently changed files.
  5. Restore infected files with copies from the official repository or a clean backup.
  6. Replicate any customizations made to your files.
  7. Test to verify the site is still operational after changes.

 Clean Hacked Database

Usually hosting providers offer PHPMyAdmin to manage your database. If you do not have any tool, you can use Adminer or MySQL Workbench.

How to  remove a malware infection from your database tables

  1. Log into your database admin panel
  2. Make a backup of the database
  3. Search for suspicious content ( as suspicious links)
  4. Open the table that contains suspicious content
  5. Manually remove any suspicious content
  6. Test to verify the site is still operational after changes

Prevent Reinfection

Hackers always leave a way to get back into your site. More often than not, we find multiple backdoors, malicious admin users, and overlooked vulnerabilities.

Start with your computer

We always recommend you to manage your site from a secure terminal. So be sure to have an antivirus program installed. All the people that access to your website, blog or e-commerce must be secure.

There are several free antivirus solutions as Avira or Avast, or paid as Kaspersky or Sophos.

User Accounts

Another important step is to change and clean up your user accounts. To do so:

  1. Confirm all website user accounts are valid:
    • CMS users
    • FTP/SFTP/SSH users
    • Database administration panels (PHPMyAdmin, etc.)
    • cPanel accounts
    • Hosting company logins
  2. Change all passwords for all users.
  3. Enable two-factor-authentication if it is available.

Patch Vulnerabilities

It is crucial to update all the elements of your website. We know it takes time, but worth it. So, make sure to update:


This can be one of the main reasons for reinfection. If you don’t close all backdoors your site will be reinfected. So, look for files named similar to CMS core files but located in the wrong directory.

Usually backdoors include this PHP functions: base64, str_rot13, gzuncompress, eval, exec, create_function, system, assert, stripslashes, preg_replace (with /e/), move_uploaded_file


Get Google Search Console

You must have a Google Search Console account to review the warnings on the messages section.

Other popular blacklist authorities are McAfee SiteAdvisor, ESET, Bing Blacklist, Norton SafeWeb, PhishTank, SpamHaus, BitDefender. If you have any WeSecur plan we explain you the process of removing from a blacklist for most of these authorities.

Request Security Review

Once you have finished your clean up it’s important to request a Google review to scan your site. If you do not do so, Google doesn’t know that you have finished your site cleanup. Be sure to have your site ready when requesting as Google is limiting the times you ask for a review monthly.
