Solved: Why Linux doesn’t need Antivirus

Linux is the least used desktop operating system. Hence this OS has lesser malware attack. There are very few Linux malware out there. Using an antivirus for Linux OS is unnecessary. The reason why Linux doesn’t need Antivirus are given above.

The reasons to this less Malware phenomenon can be attributed to the following reasons:

1.Package Managers:

Unlike Windows, programs for Linux are downloaded from Package Manager and taken from the Linux distribution’s software repositories. Package managers do all the work for you. Hence installing and updating software on Linux is easier than on Windows. These repositories have trusted software files and has been vetted by Linux distribution.

2.Security Features:

Linux users use limited user accounts and have to begin the root user feature only when necessary. Both su and sudo are used to run commands with root permissions. Since many users run the system with reduced permissions, Linus OS is more secure. Also, Linux has security features like AppArmor and SELinux. Ubuntu by default has AppArmor, which is a security feature. It runs in the background. The processes damaging the security of the system are locked down with this application.


Since Linus has a very small user base and even they tend to be tech-savvy, the platform is not as easy as other OSes. Also, it isn’t as profitable to attack Linux.

Follow the basic security practices to keep your Linux system secure:

1.Update the Software: Keep your applications updated with the latest patches. Most of the plug-ins are in Java and can work on Linux. You can update the software on Linux with a single, integrated updater.

  1. Open the terminal window.
  2. Type “sudo apt-get upgrade”.
  3. Enter the user password.
  4. “Take” a look at the available updates.
  5. Click the Y key to accept the updates and hit Enter.
  6. Wait while the update happens.

2.Take care of Phishing:

Phishing is as dangerous on Linux as on other OSes. Thankfully, browsers such as Firefox and Chrome on Linux have anti-phishing filter.

3.Avoid questionable commands:

Learn more about the authenticity of the commands before typing them into the terminal.

Overall, an antivirus software on Linux isn’t necessary if you avoid outdated extensions and plugins, irregularly updated cross-platform apps, and unchecked USB drives.
