Best free cPanel antivirus, antimalware & scanner

cPanel is the most important software tool for online web hosting service providers and protecting it is a top priority both for the company’s reputation and customers’ safety.

cPanel is by far the most popular web hosting control panel in the market with over 85% market share. Also, it is safe to say that cPanel is the most important piece of software a hosting provider needs to manage all the customer-related processes.

cPanel’s popularity also attracts hackers who are trying new methods every day to to breach the system, which makes cPanel security is a top priority for every web hosting service provider that uses cPanel. In this article, we will take a closer look at the antivirus solutions for cPanel that can help service providers to protect themselves against attacks and virus/malware.


ClamAV’s security solution within cPanel enables users to scan various directories such as mail folders, the entire home directory, public FTP, and the web directory. Upon detecting a security threat, it prompts users to take action. ClamAV also provides information on the number of scanned files, the remaining files to be scanned, and a list of identified malicious software.

However, when compared to alternative antivirus software, ClamAV may fall short of expectations. Research indicates that its Windows solutions can detect less than 20% of malware, and its Linux solution detects less than 70% of malware. Some third-party companies offer additional malware signatures for ClamAV to enhance its detection rate for PHP files, but these often come at a significant cost.

As a free and open-source antivirus solution, ClamAV lacks professional support, making it challenging to find the necessary online resources from community websites. Primarily focusing on mail gateway protection, ClamAV misses several essential features that users may require. Furthermore, its interface appears outdated and can be confusing at times.


  • Open Source: ClamAV is an open-source antivirus solution, which means it’s freely available for users and developers to use, modify, and distribute.
  • Integration with cPanel: ClamAV integrates well with cPanel, a popular web hosting control panel. This integration allows users to easily scan mail folders, home directories, public FTP, and web directories.
  • Cross-Platform Support: ClamAV is available for both Windows and Linux platforms, making it versatile and suitable for different server environments.
  • Mail Gateway Protection: It is particularly effective for mail gateway protection, offering robust scanning capabilities for email attachments and content.
  • Low Resource Usage: ClamAV is known for being lightweight and using minimal system resources, making it suitable for servers with resource constraints.


  • Detection Rate: ClamAV’s detection rate, especially on Windows, has been criticized in various research studies. It may not be as effective as some commercial antivirus solutions, detecting less than 20% of malware on Windows and less than 70% on Linux.
  • Lack of Professional Support: Being open source, ClamAV lacks dedicated professional support. Users often need to rely on community forums and resources, which may not provide the level of assistance required in critical situations.
  • Limited Features: While ClamAV is proficient in mail gateway protection, it lacks many features found in comprehensive commercial antivirus solutions. This limitation might be a drawback for users who require a more extensive range of security features.
  • Outdated Interface: Some users find ClamAV’s user interface to be outdated and less intuitive compared to more modern antivirus solutions. This can lead to confusion, especially for users who are accustomed to more user-friendly interfaces.
  • Dependency on Third-Party Signatures: To improve detection rates, ClamAV users may need to rely on third-party companies for additional malware signatures. However, these often come at a cost, negating the perceived advantage of a free antivirus solution.
