His articles are carefully crafted with this goal in mind - making complex topics more accessible.


  1. Sophos and Comodo no longer supply Linux security software. This Article pretends to be current but is not.

  2. 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.

  3. 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 Lots of complaining here, talk of windows, lack of facts, outdated information.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.

    Easy to do.

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

  5. 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

    • That is true. Tho there is a kind of workaround that is editing the DEB file to change the dependency that causes the problem libssl-0.9.8 to libssl-1.0.0. But still, as of june 2022, seems Comodo stopped supporting updates of the virus definitions from the program GUI. I tried doing manual updates, downloading the definitions file from Comodo site, but it seems the latest definitions are not recongnized by the Linux version anymore

  6. 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.

  7. The list is appreciated but seems to be outdated.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.

  8. Seqrite AntiVirus for Linux shields your Linux systems against malware. It offers On-demand and Schedule scanning, Samba Share protection, and Web Security.

    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…..

  9. I use Norton for my computer and it’s one of the best antiviruses I ever used till now.

    • 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.

  10. 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.

  11. 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?

  12. 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.
