Best Antivirus for Linux 2020 – Do You Need One?

Best Antivirus for Linux 2020 - Do You Need One?

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.

Why 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 the 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.

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.

Best antivirus for Linux

1. ESET NOD32 Antivirus for Linux

When developing a product for Linux, most antivirus companies focus on business solutions. Fortunately, there is an excellent antivirus solution for home Linux users — ESET NOD32 Antivirus for Linux. The software is extremely easy to set up and use, so it is the most convenient antivirus solution for private users.

Despite ESET not being the most popular brand on the market, it has millions of users around the world. It regularly takes the highest positions in various independent tests. The ESET antivirus engine uses ThreatSense.NET, a timely detection system. The technology continuously collects data on new malware behavior from ESET users and then informs the entire ESET network, allowing you to stay one step ahead of any new threats.

Like most home antivirus programs for Linux, ESET NOD32 Antivirus for Linux does not offer a lot of advanced features. This is obvious when compared to Windows products which often include secure VPN connection and identity-theft protection services. However, it is still exceptionally good for everyone.

Basic features

  • Antivirus and Antispyware modules — utilities that monitor not only standard viruses, but also utilities that collect personal information.
  • Device control. The antivirus monitors all the connected drives and checks them for dangerous applications. It will help you not to spread viruses for other operating systems from your infected Linux computer.
  • Antiphishing module (protection against fake sites that steal personal data). This is a useful tool for those who are not very attentive to the resources they visit and frequently access unprotected and fake sites.
  • Minimal impact on the system resources.

Pros

  • Reliable real-time protection against all types of malware with the ThreatSense.NET timely detection system.

Cons

  • Few features apart from anti-virus scanning — no network security or privacy tools.
  • No email gateway (provided by most antivirus programs for Linux).
  • No free version — to use it, you must get a subscription.

ESET NOD32 Antivirus for Linux provides excellent protection against malware with a simple and intuitive user interface. This makes it an excellent choice if you are new to Linux and want reliable antivirus protection without extra features.

For example, Bitdefender’s patented Process Inspector can detect bodiless malware, an increasingly common cybersecurity threat.

It uses anti-cryptor technology to continuously scan saved files, detects and blocks unauthorized encryption as a possible ransomware attack at an early stage. You can install Kaspersky remotely on Linux, Windows, and macOS workstations without having to manually configure or even reboot your computer. This allows you to protect every workstation in your company and prevent data leak and virus attacks.

  • It also gives you full control over your network screen. You can manage incoming and outgoing connections from a single console.
