The Importance of Malware Protection
Malware is a major threat to servers connected to the internet. Hackers and cybercriminals use malware to gain access to sensitive information, steal data, and damage or disrupt systems.

That’s why it’s important to take the necessary precautions to protect your system from malware threats.

It is also updated regularly with new virus definitions to ensure that it can detect the latest threats.

Easy to Use
ClamAV is easy to use and has a simple command-line interface. It also has a graphical user interface (GUI) called ClamTk, which makes it easy to run scans and view reports. ClamTk is available for Ubuntu and other Linux distributions.
Flexible Configuration
ClamAV has a flexible configuration that allows you to customize how it scans files and email attachments. You can configure it to scan specific directories, exclude certain files, and quarantine infected files. This makes it easy to tailor ClamAV to your specific needs.
Integration with Mail Servers
ClamAV can be integrated with mail servers such as Postfix and Sendmail to scan incoming and outgoing email attachments for malware. This ensures that your email system is protected from virus-infected attachments.
Supports Multiple Formats

ClamAV uses a signature-based approach to detect known malware threats. This means that it can only detect threats that have a known signature. It cannot detect zero-day threats or unknown malware.
No Real-Time Protection
ClamAV does not provide real-time protection, which means that it cannot prevent malware from infecting your system. It can only detect and remove malware after it has already infected your system.
No GUI
Although ClamAV has a GUI called ClamTk, it is not as feature-rich as other antivirus software and can be difficult to use for some users.
No Technical Support
