As one of the very first OSs to adopt the Linux Kernel, Debian has found its way into our homes and consolidated its supremacy as the most popular edition for home users, thus paving the way for numerous other distributions (Ubuntu included).

Debian is constantly updating and new packages are uploaded regularly. The latest version, Debian 11, was released in 2021. After almost 3 decades of existence, it’s still going strong and we’re fascinated.

What’s more captivating is that Microsoft has spotted the enormous potential of this powerful platform and started publicly endorsing the Debian distribution and Linux as early as 2015.

Microsoft loves Linux – a motto for posterity

➡ A full Linux Kernel with native support for Linux GUI apps is integrated into the Windows 10 and Windows 11 environments, along with updates, Microsoft Store presence, and all.
➡ Unsurprisingly, the Windows Subsystem for Linux (also called WSL) runs on a Debian subset. If you’re intrigued about it, don’t be shy to explore this feature and install the Linux Bash on your Windows 10 PC.
➡ Or maybe you’re more of a Windows 11 enthusiast? Don’t worry, we also got your back with some useful tips on how to dual boot Windows 11 and Linux.

Since protecting the things we value most comes naturally, it makes perfect sense to search for a good antivirus for Debian. But here’s where the plot unfolds: wasn’t Linux supposed to be virus-free?

Many still think so. Some praise its root access-based infrastructure that separates root processes from user-associated processes in order to prevent harmful executables activated at the user level to infiltrate and further contaminate privileged (or root) components.

Others are more inclined to praise enhanced Linux security patches that are publicly disclosed, generally the same day a vulnerability is revealed.

Finally, there are those who believe that Linux distros, Debian included, are simply not plagued by viruses because they are not that profitable as other more mainstream OSs, and thus less attractive for hackers.

While it does have the reputation of a reliable and secure operating system, the truth is Linux along with its various distributions requires virus protection as much as any other platform.

Can Debian be hacked?

Debian steadily becomes an increasingly attractive target for hackers

Up until this point, there has been no widespread virus infection across any Debian instances. This, combined with enhanced security measures and the fact that it claims a smaller market share compared to its counterparts makes Linux-based OSs less prone to viruses.

However, the status quo is shifting. Debian’s virus-free reputation is precisely what attracts more newcomers. And popularity boosts rarely pass unnoticed.

Wherever people are flocking, there is potential to make a profit, and hackers know it very well. This kind of unwanted attention implies that Debian is steadily turning into an increasingly attractive target for cybercriminals.

With more enticing and lucrative perspectives on the rise, hackers are more motivated to develop Linux and Debian-specific viruses, coded to exploit Debian vulnerabilities.

Hybrid malware is also a reason for concern. Windows and Linux codes are intertwined and cross-platform malware can also exploit Windows code embedded in Debian’s infrastructure.

Debian users can be tricked into downloading harmful content

Downloading files from unreliable sources can open the door to mayhem and havoc. Impossible, you say? Unfortunately not.

Officially, both Debian and the Linux kernel contain only free software with verified sources. However, paying software can still be downloaded from online repositories that are not hosted in-house.

Third-party repositories provide external software including codecs, programs, and more. Not all proprietary packages that you find in these repositories comply with regulations.

Even though they are not included in the official installation media, the fact that they are easily accessible makes it just as easy to install unverified software.

Does Debian need antivirus?

Debian GNU/Linux requires virus protection and it even incorporates virus scanning packages into its official distribution in order to allow you to build gateways with antivirus properties across various protocols.

Needless to say, Debian endorses open-source, distributable antivirus environments such as ClamAV. But that does not mean you cannot properly install and deploy proprietary antivirus software in the Debian system.

In fact, we are quite proud to present you with our selection, where you will most likely find the best antivirus for Linux Debian. As one would expect, we mostly deal with Windows-based test cases here, at Windows Report.

The novelty of Linux was even more enticing for our expert QA team and they enjoyed crafting an entirely new methodology that allowed us to test each antivirus to its limits and in some cases even beyond.

In fact, stress-testing is one of our favorite methods to determine which software has what it takes to make the cut and which ones don’t. Naturally, you’ll have to throw your own criteria into the mix to find that fine-tuned, perfectly tailored program that best suits your needs.

But we are convinced this review has a bit of something for every Linux aficionado out there. Without further ado, here’s how our selection process went.

F-Secure Linux Security

  • Graphic user interface and command line-based edition available
  • Advanced intrusion detection mechanisms
  • Smart firewall included
  • Solid malware removal capabilities
  • Centralized endpoint management
  • The CLI edition does not provide real-time protection.

F-Secure Linux Security is a top-rated antivirus for Linux and we simply love the fact that it does not cater exclusively to a particular type of user.

Generally speaking, Linux antiviruses have the tendency to privilege more knowledgeable users that are at ease with running long strings of commands via the terminal.

It’s safe to say that F-Secure delivers solid malware defense for everyone involved with this OS, from seasoned users to newcomers without being detrimental towards one or the other.

And it does so by providing both CLI and GUI editions across numerous Linux distributions ranging from 32-bit to 64-bit iterations such as Ubuntu, Debian, Suse, and more.

Similar to Bitdefender’s solution, this antivirus for Debian covers both desktop clients and servers, thus tackling every single aspect of your digital defense.

But that is pretty much where similarities end. Now, unlike our previous entry, F-Secure Linux Security includes a smart firewall and sophisticated intrusion detection algorithms to seal your network against exploits of all kinds.

In fact, it’s best known and most cherished for its cutting-edge Intrusion Detection system along with robust real-time protection against malware and simplified controls reunited in a comprehensive dashboard that includes all terminals where the F-Secure security agent is deployed.

Highly versatile, this antivirus for Debian Linux allows you to configure a GUI or CLI-based interface and pick out whatever suits your needs best.

The only downside for us is that you cannot enable real-time protection in the command line-based edition. However, it’s a pardonable hiccup and if you prefer a more graphical approach, it will not hinder you in any way.

Here’s what you’ll need to run via the terminal if you’re running Debian 10 or later versions:

# echo "deb http://deb.avast.com/lin/repo debian-buster release" \
>> /etc/apt/sources.list

Then, install the Avast public key, update the package manager state and you’re all set.

Speaking about updates, this best antivirus for Debian runs a cron every hour and relies on a shell script to check, download and install the latest virus definitions.
