Wondering whether Ubuntu needs antivirus software? You’re not alone. I used to feel it was overkill. But with Ubuntu’s rising popularity and the growth in AI-generated malware, having a bit of protection makes sense.
Recent incidents like the “Koske” malware hidden in seemingly harmless AI-generated images, targeting Linux-based JupyterLab servers, show that attackers are evolving fast (source). Supply chain compromises and privilege escalation flaws on Linux aren’t just theoretical, they’re happening in real-time.
That’s why having antivirus on Ubuntu 24.04 is more than just a style choice, it’s a smart precaution.

Why AI-Powered Malware Makes Antivirus More Important
AI is now part of both sides of cybersecurity. On one hand, antivirus engines are using AI to detect new threats faster. But attackers are also using AI to mutate malware and create new attack vectors.
This arms race makes it clear: even on Ubuntu, having antivirus protection in 2025 is a smart move.
