Best Antivirus for Linux

Best Antivirus for Linux 2021 - Do You Need One?

Quick answer: The Best Antivirus for Linux in 2024 is ClamAV!

It’s not usual to hear about virus attacks on Linux computers. It’s generally accepted that Linux is much more secure than Windows and viruses for Linux simply do not exist.

However, just by using this operating system, you are not automatically protected against viruses and malware. Even if you use the system properly, in many cases, antivirus software can play a significant role in protecting your confidential files. Moreover, today we hear about more and more attacks targeted at Linux devices.

The number of viruses is gradually growing. So, using an antivirus solution is not so bad idea, especially when your business uses Linux. One attack can highly influence your productivity and destroy business processes. Let’s see why you should use antivirus for Linux and which are the best products.

1. Do you really need an antivirus for Linux?

01 ubuntu

Linux is considered to be a reliable operating system because it is less vulnerable than Windows. Most user PCs run on Windows, so the number of viruses and malware developed for this platform is far greater than for others. However, this doesn’t mean that Linux doesn’t need protection from viruses.

There are several reasons to consider installing an antivirus app on your Linux computer:

  • The chances of unauthorized access to your PC. If your device is permanently connected to the Internet, hackers can steal information from it.
  • Trojans that mask themselves as browser extensions or useful apps. You can catch them when visiting suspicious resources. The apps will send spam from an infected computer.
  • A Linux PC cannot be infected by viruses for Windows. However, it can spread viruses to other devices.
  • Spy bots can monitor and copy personal data from a computer.
  • If you use two operating systems on your device, you can scan files of the second operating system while running Linux.
  • To perform certain actions, you need superuser rights. So, if you like to run most tasks under root, the antivirus will protect your system from a crash.
  • Your PC runs as a server — in this case, you can infect other devices in your network, especially if these are Windows computers.

2. What to expect from Linux antivirus?

By using the antivirus for Linux, you can expect the following features:

  • Protection against phishing. Many resources steal personal information from users by using fake sites. Good antiviruses can detect such resources and block access to them.
  • Control the files on the server. Often, antiviruses are used to monitor the status of the server and the files on it.
  • Detecting and removing viruses for Windows and macOS if you use dual boot. To prevent Linux from being an incubator and distributor of viruses, antiviruses for Linux can clean the device of threats for other operating systems as well.

Now, let’s review the best antivirus apps for Ubuntu. Why Ubuntu? Because this is the most popular Linux distributive. Most apps are compatible with Ubuntu and Ubuntu-based distributives first.

    Nice review, however, Eset NOD32 & Ubuntu are not that well suited and feels like Eset are not really committed to Linux.
    1) The installer looks awful on ubuntu gnome with adwaita dark theme – white text on white background highlighted in white! Thankfully when highlight the text turns to light grey. Eset knew of this issue in Feb 2020, still not fixed.
    2) On The 19th of Nov 2020 an AV update caused Nod32 to stop. No identifiable UI notification, messages in Syslog, for those that read the logs every day. Eset finally admitted an error on their forum, with a workaround, but then deleted the workaround post. Eset didn’t email users about non-functioning AV.
    3) Latest version (27 Oct 2020) GUI control app, doesn’t work on Ubuntu 20.10 Gnome 3.38.1 using the Wayland display terminal.
    4) Installer and app report ‘Failed to load module “canberra-gtk-module”‘, Eset knew of this issue in Feb 2020, still not fixed.

    I have been using ESET on Debian and Manjaro – all good. Except the product is to be discontinued next year. I have not received any notification from the company but there is a notice on the website. Only business products supplied from mid 2022.

    This article seems outdated. For example, ESET NOD32 ended software downloads as of 3 August 2021 and are ending support (security updates) as of 3 August 2022. ESET, like the other software developers who no longer offer Linux home user antivirus/security software (including Sophos, BitDefender, Avast), are instead offering an Endpoint antivirus//security software solutions. However, these are primarily designed for business use, i.e. servers and computer networks. If you research the prices of some of the Endpoint software for Linux, the prices are way too high for home users. The prices for Endpoint antivirus/security software on Linux are aimed at business users. Current users of ESET NOD32 appear to be offered a replacement, both ESET Endpoint and ESET Protect, one is to control the software (like would be used for remote servers) and the other one for the antivirus/security software application itself (I may have those two mixed-up). The functionality does not appear to be anywhere near as good as ESET NOD32 for home users such as for example, no ability to set-up automated scans, cannot manually scan individual files, no email scanning. So it looks to me as though Clam AV (made by Cisco?) maybe the only antivirus still available for Linux home users in 2022?? I’ve read other Linux antivirus software articles like this one with “2022” in their titles, the articles no longer applied as of 2021, or earlier, for most of the software reviewed.
