While ChromeOS blocks most traditional viruses through built-in security features, malware can still slip through via browser extensions, phishing, and compromised apps.

This guide covers how Chromebooks get infected, the top Chromebook security threats, and how you can detect, remove, and prevent malware on ChromeOS.

Can Chromebooks get viruses?

Yes, Chromebooks can get infected with viruses or malware, though it happens far less often than on Windows or macOS computers.

Chromebooks run on ChromeOS, which is designed from the ground up to be resistant to traditional malware. They use web apps, not executable files (think .exe or .dmg), so the kind of viruses that spread through local software can't easily take hold.

While many Chromebooks can run Android apps from the Google Play Store, most extensions and web-based tools still come from the official Chrome Web Store, helping keep the platform secure.

However, Chromebooks aren't completely secure against other forms of malware. Threats such as trojans, spyware, adware, and ransomware can compromise your device. Security vulnerabilities, like a rogue browser extension or malicious app, are the most common culprits.
