Chromebook Security: Do You Need Antivirus?
ChromeOS is built on a different security model: each tab and app is sandboxed, the system partition is read-only, verified boot checks integrity at every start, and a corrupted system can be restored by powerwashing the device.
As a result, traditional Windows-style antivirus does not run natively on a Chromebook and would have little to scan if it did.
What actually threatens a Chromebook
Malicious browser extensions, phishing pages, and — where the Play Store or Linux containers are enabled — Android or Linux apps installed from untrusted sources. None of those are addressed by a classic file scanner.
What to do instead
Review your extensions and remove anything you did not deliberately install, keep ChromeOS updated, use multi-factor authentication on your Google account, and enable Enhanced Safe Browsing in Chrome settings. If Android apps are enabled, keep Play Protect on.
Frequently asked questions
- Is there free antivirus for Chromebook?
- There is no traditional free antivirus for ChromeOS, because the platform does not work that way. Browser extensions and Android security apps are the only real options, and neither replaces the OS's own protections.
- Can a Chromebook get a virus?
- Classic file-infecting viruses, effectively no. Malicious extensions, phishing and rogue Android apps, yes.
