Best Linux Antivirus: Top 10 Reviewed and Compared

There are always errors and problems in the computer Operating System, especially intentionally made mistakes, which we call trojan, malware, viruses. Linux OS is a much more efficient and secure OS, but still, there are possibilities to have these problems. To decreasing these issues, a security specialist has developed a Linux antivirus to detect and remove those threats before they harm the system.

Best Linux Antivirus

In online, you can find lots of different antivirus suggestions. Recently, an independent IT security institute AV-Test took over the test to ensure a real Linux antivirus software list that helps us make a useful generic list of the top 10 best antiviruses for Linux.

1. Sophos

In the AV-Test, Sophos is one of the best free antiviruses for Linux. It does support not only on-demand scanning but also provides a real-time scanning feature. This particular Linux antivirus prevents Linux base malware and works fine on all the major platforms like windows android. It detects worms and trojans as well and helps to remove them from the repository. But if you are kinda geeky, Sophos provides you terminal coding facility to make it easier.

2. Comodo

Comodo is another best antivirus software for Linux. It is well known for its unique architecture support and cross-platform feature. It also supports an email scanning feature with an additional anti-virus protection system, which is not available on other applications.

Comodo supports the windows firewall feature with 32-bit and 64-bit architecture. Comodo Antivirus for Linux also supports all distros, so it widely uses among Linux users.

3. ClamAV

This is the best and probably widely referred antivirus in the Linux community. ClamAV is an open source and free to use. It is recognized as a versatile antivirus to detect trojans, malware, and viruses. It also supports standard mail gateway scanning. It is easy to use and fast to run because it doesn’t have a native GUI and works through the terminal.

  • Can run on different software architecture
  • Scanning feature for internal drive and drivers

5. Chkrootkit

From the name, Chkrootkit, you can guess it really works on a root, and frankly speaking, it is the best option for rootkit available in a Linux system. IT is lightweight and portable. You can quickly burn it to CD or USB. It contains multiple programs to support users like.


  • Rootkit detection
  • Lightweight
  • Portable
  • Easy to use and fast
  • Run from terminal

6. Rootkit Hunter

Rootkit Hunter is another best option for the rootkit. It works on command and uses backdoor and other local exploits to detect all kinds of viruses, including trojans. A rootkit is developed on Bourne shell with an SHA-1  hash comparison for better service with portability feature. This particular software is available for different distros.

  • Opensource
  • Free
  • Works from GUI
  • Support on-demand scanning

8. BitDefender

This can be your next antivirus for Ubuntu. In the Linux community, BitDefender did an excellent job as a Linux antivirus software. Here is a, but we have to think that it is not free as a Linux antivirus software; you have to download the trial version. But within this trial, it is still the best antivirus software for Linux.


  • It scans archives.
  • Desktop integration supports.
  • Intuitive GUI and also supports a command-line interface
  • Quarantine infected files into a protected directory.

9. ESET NOD32 Antivirus 4

In the AV-Test, ESET was first ranked and selected as the best antivirus for Linux or Ubuntu. But the software is not free. You can have it as your ubuntu antivirus for a limited time and as a trial version. But if you think about its feature, then the price won’t be a problem.

It can be said that this particular Linux antivirus is the best for malware detection built for Linux only. But you will get surprised by the result because it also detects viruses for other  OS malware and trojans.


  • The best virus, malware, detector selected by AV-Test
  • Best antivirus and antispyware
  • Spying detector
  • Home and industrial level solution
  • Network security
  • Automatic update

10. Avast Core Security

One of our final best choices is a Linux antivirus. This Linux antivirus also came up among the best in the AV-Test. It works with Ubuntu and other Linux distros 32-bit and 64-bit software architecture. This Linux antivirus supports core security, network security and also provides file server security. This software you can download from here. But this version is a trial version, but it works way better than other available free versions.


  • Real-Time Protection and anti-spyware
  • On-demand scanning and planned scanning function
  • Core security, network security
  • Home and industrial safety
  • The regular update for assuring new threat

Final Thought

Finally, I tried to bring you the best antivirus software for Linux systems based on different categories like price, availability, reliability, and reliable online test result. From the beginning, I described the free version and believed that you might find it the best option for your Linux device. Later parts are trial versions but offer some excellent and useful options as the best antivirus for Linux. All those above Linux Antivirus will keep your device and your data secure.


  1. ESET NOD32 for Linux Desktop is also EOL. Their proposed alternative is to switch to an enterprise solution that costs a minimum of 5x the price (ESET Endpoint Security). Frankly, I don’t understand why AV companies don’t just opensource their code but continue charging for the virus definition update service. That’s pretty much the only reason we pay them anyway.

  2. Offer a solution or say nothing. Lots of complaining here, talk of windows, lack of facts, outdated information.
    Linux isn’t Windows. read the instructions and install correctly per the instructions. It works, all of the time , every time.

  3. Every OS (operating system) that needs an antivirus software was designed with its backdoor WIDE OPEN for hackers. Just saying.

  4. Seriously, COMODO on Ubuntu is a complete JOKE, it fails to install and is looking for removed libraries and thinking of how many home users are using newer versions of Ubuntu (past 12.04 where comodo worked) it should be removed from the list, which leads me to believe the Author is getting kickbacks

  5. So what if something doesn’t have a GUI, command line is MUCH LESS bloat usually, and often easier when you’ve used it enough.

  6. The list is appreciated but seems to be outdated. With Ubuntu 18.04 I find that Sophos states on installation that it does NOT have on-access protection (and I can’t seem to get it running anyway); Comodo requires a support file that no longer exists (won’t run without it and it is listed as “removed”); rkhunter and chkrootkit are the go-to root-kit tools but really don’t do other sorts of malware – and are rendered less effective by known and growing false-positives. I’m still working down the list but the feature that I really need to make Ubuntu (or any Linix distro) a viable home-desktop system is the ability to scan traffic coming in on the web. So far it’s been fat-finger miss-access to web sites that have been the source of troubles.

  7. Seqrite AntiVirus for Linux shields your Linux systems against malware. It offers On-demand and Schedule scanning, Samba Share protection, and Web Security. The Advanced Device Control enforces a complete governance over the use of removable storage devices, which helps to keep your system safe and secure. It is easy to use and supports wide range of 32-bit and 64-bit Linux distributions.

    Powerful Scanner
    Create scheduled scan for selected files and folders that can run automatically at given date and time, and set appropriate action items using various commands.

    Real-time Protection
    Real-time antivirus protection that detects and automatically cleans all types of virus, worms, Trojans, spyware, adware etc.

    Web Filtering
    Blocks access to certain categories (social networking or gaming) of websites or an individual website or exclude a website even though its category is blocked.

    Advanced Device Control
    Enforces complete governance over the use of removable storage devices, which helps to keep your system safe and secure.

    SAMBA Share Protection
    It enables users to scan files as soon as they are copied to SAMBA Shares and thus helps to prevent any kind of virus infection from spreading.

    Detailed Reports
    View the detailed information of virus scan incidents and logs of update.

    • Seqrite AntiVirus for Linux May be great but when price is not mentioned on the website you have to wonder…..

    • Norton is only available for Windows systems and has always been garbage. Norton typically rates between 20th and 30th on the AV-comparative lists year-after-year. Norton products are never able to detect and block as many malware samples as most of the other AV programs. Norton provides less protection for more money – don’t confuse them having a big company with quality software. Norton is not great and has never been.

  8. Bitdefender is free for home users. You have a 30 day trial in which you can request a free home user licence for one year.

  9. I think this information is quite outdated, I have just installed Sophos and it doesn’t bring a GUI for Linux anymore.

    • Thanks for the comment. Sophos is a quite good application. If it does not fulfill your requirement, you can always install another one from this list. And if the Sophos does not support GUI, soon I will be correcting the content.

      • Yeah, Sophos dropped their GUI. It’s CLI now but still probably the best. You really couldn’t go wrong with any of these. Good article.

        I use antivirus to protect my Windows box more than for protecting Linux. I am a guitarist and my Windows computer serves as a recording studio and pre-amp. It has been highly modified and is never allowed to access the Internet. Any updates and software needed come through my Linux machine so I need a virus scanner for that.

        • Michael : I have been looking for any sort of Sophos Linux AV download, and I have not seen any mention of even just a CLI version. Do you have any links for that?

  10. Whether one needs protection for a single device, a smart home, your small business, hybrid infrastructure or Enterprise data center, now best antivirus services have the product that delivers the best security, unparalleled performance and incredible ease of use. Multi-layer ransomware protection to keep files safe is just another achievement that big names have achieved.
