Why Doesn’t Linux Need Antivirus?

As a Linux user, I was curious to why people always say “Linux doesn’t need antivirus”.

So, what’s different about Linux? Why wouldn’t it need Antivirus?

Linux is still an operating system. So yes, It can still get some nasty malware.

Let’s think about this.

The most popular operating system usually is the main target. Pretend you’re going to make some malware, and you want to infect some users. Which operating system should you target? Are you going to use the most popular operating system? Or the operating system nobody uses?

Microsoft’s Windows is by far the most popular operating system as of 2020.

So, Linux just isn’t targeted for malware as much. Is that the only reason though?

No! Unlike Windows, Linux is open source. That means anybody can view and edit the Linux code themself. Making Linux open source is a great idea for security, this is because the Linux community can help find bugs and security vulnerabilities and help fix them.

Linux is a very secure operating system. You should use it.

I hope this post will help you to understand why Linux doesn’t need antivirus.

  1. This is a very good point, when malicious actors try to get their malware on as many computers as possible they make it so it’ll be compatible with the most amount of machines.

    This is certainly true for desktops, but what do you think about how the vast majority of servers are running linux hosts? (https://thecloudmarket.com/stats#/by_platform_definition).

    I think Linux is a better designed and written operating system than Windows :-). Here’s a good list of security features/systems in Linux that are worth digging into: https://kernsec.org/wiki/index.php/Projects

  2. I’d be curious what the overall security profile is for non-mainstream OSes. For example, is the smaller number of code contributors/reviewers that the BSDs have offset by their lower adoption rate? I’d imagine that you’d be more impervious to mass malware campaigns (at least those directed at the OS level), but if you were targeted specifically, I’d assume there would be more undiscovered vulnerabilities that could be exploited.
