Antivirus software is the requirement of today’s IT Infrastructure. Linux is mostly used by the developers for individual use and used by the system administrator team for corporate IT server setups.
Before I proceed on choosing the best antivirus tool for Linux, it needs to be evaluated what type of server is built on Linux, what type of usage, and so on. In addition to this, what is licensing structure, pricing, and features each tool provides are equally important before making the right choice.
Antivirus Tools for Linux
- ESET (Personal Use)
- Avast (File server)
- Bitdefender (Small Business)
- McAfee (Enterprise)
- Kaspersky (Medium Scale Businesses)
ESET (Personal Use)
For Linux desktops, antivirus software is hard to find. ESET is the one that is only used for desktops. It comes for all three (Windows, Mac and Linux) platforms. Licensing cost is no different for platforms.
In case the user wants to switch from Linux to Windows, the same antivirus license can be used at no extra cost.

Avast (File Servers)
File Servers are prone to spread viruses across enterprise or office networks. Linux-based file servers can be protected by the Avast Security tool. Malware protection is the need for secured data.
Avast comes with the package of file server security, network security, and core security. Combining all of these makes the tool perfect for small, medium-scale IT setups.

Bitdefender (Small Business)
Bitdefender’s GravityZone product provides small businesses IT security from malware threats and firewall protection. Most importantly, at affordable prices.
The tool offers vulnerability assessment features by running a report of misconfiguration or issues that each computer within the network has. Proactively, the tool offers protection before any damage to network/computers occurs.
The features offering by Bitdefender are:

Kaspersky (Medium Scale Businesses)
Business computer networks usually comprise all platforms. Servers are built on Linux, where development machines are Windows or Mac or Linux.
When it comes to antivirus solutions, it should support hybrid networks. Kaspersky is a security solution that supports hundreds of machines in a network. It provides an easy to deploy the solution to the IT Operations team.
Its anti-cryptor is a powerful feature to detect ransomware. Absolutely No compromise on security.
Kaspersky’s advantages for Linux Antivirus solution are as follows:
