Does Linux need antivirus? An honest answer

Here's the honest answer: most home Linux desktops don't need a traditional, always-on antivirus. That's not because Linux can't be attacked. It's because the things that keep a Linux desktop safe are mostly habits and settings, not a resident scanner running in the background.

Why Linux is a smaller target at home

Most desktop malware is written for Windows. On top of that, Linux installs software from checked, signed repositories rather than random downloads, and it keeps everyday users out of the parts of the system that malware wants to reach. Those two things stop most problems before they start.

What actually keeps you safe

Four habits do most of the work.

Install from trusted sources. This is the big one. Stick to your distribution's repositories or trusted formats like Flatpak, and you avoid the most common way malware arrives.
Keep your system updated. Updates close the holes that attackers rely on.
Work as a standard user, so nothing can change your whole system without your password.
Be alert to scams. Most real-world attacks on any platform come through your browser and inbox, not the operating system.

When antivirus does make sense

There's one common case: scanning files you'll pass on to Windows users. A Linux file can carry Windows malware harmlessly and then infect a colleague's PC. If you share files a lot, an on-demand scanner like ClamAV is worth having.
