In 2025, digital threats have evolved—subtle, fast, and increasingly deceptive. Chromebooks, known for their lightweight design and cloud-first approach, have long been considered “safe” compared to traditional laptops. But that narrative is changing. As more users rely on Chrome OS for both personal and professional tasks, security is no longer optional—it’s essential.
So, what’s the best antivirus for Chromebook in 2025? Let’s break it down, with human clarity and tech-smart logic.

The idea that “Chromebooks don’t need antivirus” simply doesn’t hold up anymore.
