Whether you run a personal blog or manage a major e-commerce platform, your website is vulnerable to attacks. Hackers can exploit vulnerabilities in your website’s software, server, or even third-party plugins to inject malware. Once infected, your website may display unwanted ads, collect sensitive user data, or redirect visitors to malicious sites. Worse yet, Google may blacklist your website, blocking potential visitors, and hurting your SEO rankings.

How to Check Website for Malware

That’s why regularly conducting a check for website malware is essential to maintain both your reputation and your visitors’ safety. In this guide, we will cover what malware is, how it can infect your website, and the methods you can use to detect it.

Let’s begin our journey!

What is Malware?

Malware is short for “malicious software,” and it refers to any type of harmful code or program designed to disrupt, damage, or gain unauthorized access to systems. There are various types of malware that can affect websites, including:

  1. Viruses: These can spread across a website or server, compromising its performance and functionality.
  2. Worms: A self-replicating type of malware that can quickly infect large parts of your website’s infrastructure.
  3. Trojans: Hidden malicious code that is disguised as legitimate software or updates.
  4. Ransomware: A type of malware that locks access to your site, demanding payment to restore control.
  5. Spyware: Malware that monitors user activity on your website and collects sensitive information such as login credentials or payment details.

Understanding these types of malware is the first step to learning how to properly check a website for malware and eliminate it. Now, let’s move on to the practical steps you can take to ensure your website remains malware-free.

How Malware Infects Your Website

Before diving into how to check your website for malware, it’s important to know how malware infects websites in the first place. Here are some common methods:

1. Outdated Software

Keeping your website’s software and content management system (CMS) up to date is crucial. Hackers often exploit vulnerabilities in outdated software to inject malware.

2. Unsecured Plugins and Themes

Many website owners install third-party plugins or themes to enhance their site’s functionality or aesthetics. However, if these plugins and themes come from unreliable sources, they can serve as a gateway for malware.

3. Weak Passwords

If you or your website’s users have weak passwords, cybercriminals can easily brute-force their way into your system. Once inside, they can inject harmful code, compromising your site’s integrity.

4. Infected Devices

In some cases, the computer or device you use to manage your website might already be infected with malware. When you upload files from that device to your site, the malware spreads, compromising your site.

Now that we’ve covered how malware can get into your website, let’s explore the various ways to check your website for malware.

How to Check Website for Malware?

1. Use Online Malware Scanners

One of the easiest and most efficient ways to check your website for malware is to use an online malware scanning tool. These tools analyze your website’s files, code, and server environment for malicious activities or code.

Some of the most popular online malware scanners include:

  • Sucuri SiteCheck: A free website security scanner that looks for malware, viruses, blacklisting status, and other security issues.
  • Google Safe Browsing: Google’s tool to check if your website has been flagged for containing malicious content or malware.
  • VirusTotal: Allows you to scan a specific URL or file for malware by cross-referencing it with a database of known threats.
  • Quttera: A free service that scans websites for malware, malicious code, and vulnerabilities.

These tools are user-friendly, requiring just your website’s URL to perform a comprehensive scan. They provide a detailed report highlighting any potential malware threats, giving you peace of mind or pointing out where further investigation is necessary.

2. Check Website Files Manually

For those with technical knowledge, a manual inspection of your website files is another effective method to check for website malware. By accessing your website’s server via FTP or cPanel, you can review files and directories for suspicious or unauthorized changes.

Look for:

  • Unknown Files or Scripts: If you notice files that you didn’t upload or that don’t seem to belong, they could be malware.
  • Unusual Code Injections: Examine your website’s code for strange or unfamiliar script tags. Malware is often embedded in JavaScript or PHP code.
  • Changes in File Permissions: If file permissions have been altered without your knowledge, it could be a sign of malware.

Manually checking your website for malware can be time-consuming and requires a certain level of expertise, but it offers deeper insight into the workings of your website.

3. Review Website Logs

Your website’s logs hold a wealth of information regarding the activity on your site. Checking these logs can help you detect unusual or unauthorized access that may indicate a malware infection.

To do this, access your server logs through your hosting provider’s cPanel or use a plugin to monitor traffic and user activity. Look for anomalies such as:

  • Sudden spikes in traffic from unknown sources.
  • Unusual login attempts or successful logins from unknown IP addresses.
  • Strange requests or errors that appear in your server logs.

By regularly reviewing these logs, you can identify malicious behavior early and prevent malware from spreading.

4. Leverage Website Security Plugins

If you use a CMS like WordPress, installing security plugins can automate the process of checking for malware. Plugins like Wordfence, iThemes Security, and MalCare can scan your site for vulnerabilities and malware, while also providing features such as firewall protection, login security, and real-time monitoring.

These plugins are often equipped with automatic scanning features, meaning they can notify you as soon as malware is detected. In some cases, these plugins can even remove malware for you, reducing the need for manual intervention.

5. Conduct a Server-Side Scan

A server-side malware scan goes beyond your website’s files and scans your entire server for suspicious activity. This method is more comprehensive, as malware may hide in your server’s root directory, infecting files that a regular website scan might miss.

To conduct a server-side scan, you’ll need to:

  • Use tools like ClamAV or Maldet, which are designed to perform server-wide scans for malware and viruses.
  • Ask your web hosting provider for server-level scanning services, especially if you’re on a shared hosting plan.

This step is crucial for identifying hidden malware that may not be apparent through traditional website scans.

How to Clean Your Website After Detecting Malware

Once you’ve completed your check for website malware and found an infection, it’s time to remove it. Cleaning malware from a website can be complex, but here’s a basic overview of the steps you’ll need to take for malware and ransomware removal to ensure your website is fully secure:

1. Isolate Your Website

To prevent the malware from spreading further, immediately take your site offline by placing it in maintenance mode. This step will help protect your visitors from encountering the malware while you work to remove it.

2. Backup Your Website

Before making any changes, create a backup of your website. This backup will serve as a reference point and can be used to restore your website in case anything goes wrong during the cleaning process.

3. Identify the Source of the Infection

Determine where the malware originated. Is it a compromised plugin, an outdated theme, or a malicious file that was uploaded? Identifying the source will help you avoid similar infections in the future.

4. Remove Infected Files

Once you’ve identified the malware-infected files, delete or replace them with clean versions. If your website was infected through a plugin or theme, uninstall it and install a clean version from a trusted source.

5. Strengthen Your Security

After malware removal, bolster your website’s security by following best practices such as using strong passwords, updating your software regularly, and implementing security plugins.
