How to install Free Antivirus on Linux OS?

Linux doesn’t always need antivirus for personal use, but on servers, shared environments, or high-security systems, it adds an extra safety layer.

Linux is generally more secure than Windows, but antivirus can still be useful because:

• 🔹 Cross-platform threats – Linux servers can host files that carry Windows or Android malware, spreading them to others.

• 🔹 Targeted attacks – Although rare, Linux malware (like rootkits, trojans, cryptominers) does exist.

• 🔹 Web & mail servers – Antivirus helps scan attachments or downloads to protect users.

• 🔹 Compliance – Some industries require antivirus for regulatory reasons.

• 🔹 Defense in depth – Extra protection against zero-day exploits or misconfigurations.
