I have been computer free for probably 15ish years until I recently bought and set up a RPi4 with Linux. It’s been fun but I’m not really a super user so I’m looking to back to Windows as my main OS.
- is antivirus a necessity? I will be gaming and streaming on my new setup.
If yes then
- what are some ideal options? Paid or free.
Thanks for your responses in advance.
I don’t think dedicated antivirus software is really required anymore. I haven’t run third-party AV software on any of my systems in the last decade.
On Windows, the built-in Windows Defender is good enough for most use cases. When it first launched Defender had a pretty bad track record at stopping viruses, but now it routinely ranks at the top.
On Linux, antivirus software has never really been required. One major exception I can think of would be if you’re running a file server or mail server that talks to OSX or Windows systems. Even then the AV software isn’t really there to protect the server, it’s there to make sure you don’t pass malware or viruses to those non-Linux clients.
Can you please help me understand why antivirus is not needed on linux? Are there no viruses for linuxor what?
There are some viruses that have targeted Linux, but they’re rare compared to other platforms and their ability to spread is relatively low. One of the main reasons is just down to how software tends to be installed on each platform. Viruses have an easier time spreading on Windows or OSX where users are more accustomed to downloading an executable and running it. Once there’s a malicious running process, it has a comparatively high chance to spread because it can attempt to escalate its privileges either by exploiting a bug or socially engineering the user to click through a privilege escalation prompt. That entire workflow is practically nonexistent on Linux, users just don’t tend to download and execute random binaries. Instead most Linux software gets delivered in one of these ways, each of which has impediments that reduce the chance a virus could spread:
There are some exceptions, for example some companies like Hashicorp will distribute their stuff as precompiled binaries. Even in that case you’re probably fine as long as you don’t run the downloaded binary as root. Users in the habit of downloading strange binaries from sketchy places and running them as root just aren’t very common among the Linux userbase. I’m sure there are some (and they should really stop doing that), but there aren’t enough of them to allow a virus to spread unchecked.
FWIW Linux has malware too.

That’s a cute little list
