If you’re not comfortable removing the malware yourself, consider a professional. Many malware scanning services also offer malware removal services.

Once the malware has been removed, it’s important to restore your website to its pre-infection state. This may involve restoring files from a backup, repairing damaged files, or reinstalling your website software.

Tools and Services for Malware Scanning

A wide range of scanning tools and services are available to scan your website for malware. These range from free online scanners to professional services that offer comprehensive security solutions.

Free online scanners, such as Google’s Safe Browsing diagnostic tool, can be a good starting point. They can help you identify obvious signs of malware. However, they may not catch more sophisticated or hidden threats.

Professional services offer more comprehensive scanning solutions. They use advanced algorithms and large databases of known malware to detect threats. Many also offer additional services, such as removal of the malware and ongoing monitoring for new threats.

Checking for Malware in Files

Checking for Malware in Databases

  • Utilize tools like SQL map to detect SQL injection flaws and potential malware in your databases.
  • Manually review database entries for unexpected changes or new records and ensure the backup ahead of making changes.

Checking for Malicious Code in Source Code

  • Use automated tools like OWASP ZAP or SonarQube to scan for vulnerabilities and malicious code in your website’s source code.
  • Regularly manually review your source code for unfamiliar snippets or file changes to catch anything automation might miss.

Automatic Website Scanning and Malware Removal

  • Implement automatic scanning and malware removal tools such as Sucuri, Wordfence (for WordPress), or SiteLock for continuous monitoring and real-time protection.
  • Even with automatic tools, keep software up-to-date, review scan reports, and maintain proactive security measures.

Prevention: Best Practices to Protect Your Website from Malware

A stitch in time saves nine, and this is especially true when it comes to website security. By following best practices, you can significantly reduce the risk of a malware infection.

These best practices include keeping your website software and plugins up to date, using strong passwords, and limiting the number of users access to your site.

Regularly backing up your website is also essential. Ensures that you have a clear copy of your site that you can restore in case of an infection.
