1. Introduction
Chromebooks are popular thanks to their speed, simplicity, and generally solid security. However, no system is ever fully impregnable. Malicious websites, phishing, Android app vulnerabilities, or browser-based threats can still create risk. That’s why many users ask: What is the best antivirus software for Chromebook?
In this post, we’ll evaluate antivirus apps that can run on ChromeOS (typically via Android support or browser extensions), weigh their pros and cons, and help you pick the right protection for your device. Our goal is to help you stay secure without slowing down your Chromebook experience.
2. Do Chromebooks Even Need Antivirus?
Before you install anything, it’s worth understanding the built-in protection that comes with a Chromebook—and its limits.
Built-In Protections of ChromeOS
Chromebooks (ChromeOS) include several built-in security features:
- Sandboxing: Each tab, app, or process runs in its isolated container so it cannot tamper with others.
- Verified Boot / TPM: On startup, the firmware and OS checks for signs of tampering.
- Automatic updates: ChromeOS updates frequently (often weekly) with security patches.
- Built-in safe browsing / web filtering: Chrome blocks many known malicious websites.
- Permission model for Android apps: If your device supports Android apps, ChromeOS enforces permission controls.
Because of these layers, many security experts argue that the risk of “classic viruses” on Chromebooks is lower than on Windows.
Why Some Users Still Consider Antivirus
Still, there are gaps:
- Malicious Android apps: If you sideload or install a risky app, it can carry malware or spyware.
- Phishing / browser-based threats: No built-in protection is perfect.
- Zero-day exploits or web injection: New vulnerabilities may slip through.
- File scanning: If you frequently receive files (e.g. via USB, cloud sync), you may want an additional check.
In short: Chromebooks are more secure by default, but additional protection can help harden them—especially if you use them like a general-purpose laptop.
Sources like Security.org note that ChromeOS doesn’t natively support most antivirus software, but Android apps (on supported Chromebooks) can provide extra protection.
Google’s own support pages also mention that antivirus programs don’t work in the usual way on Chromebooks—because ChromeOS is designed differently.
So the question becomes: which antivirus tools do offer useful protection without interfering with ChromeOS?
3. How Antivirus Works (and Doesn’t) on ChromeOS
It helps to understand the mechanics so you set realistic expectations.
Limitations & Differences
- Many antivirus suites can’t access the root system in ChromeOS due to its locked-down architecture.
- Most solutions for Chromebooks are Android apps (for devices that support Linux/Android) or browser extensions.
- Real-time, deep scanning of the entire OS is often not possible.
- Instead, protection often focuses on file scanning, app scanning, URL filtering, web shields, and phishing protection.
What to Expect
- Real-time protection of Android apps: Scanning apps as they are installed or run (for supported Chromebook models).
- On-demand scans: You can trigger scans of files or directories you suspect.
- Web protection / URL filtering: Blocking malicious websites before they load.
- Malware / adware / PUP detection: For files, downloads, or apps.
- System impact: A lightweight antivirus is essential — you don’t want a slow Chromebook.
Thus, choosing the best antivirus software for Chromebook means choosing one that works within these limitations while providing meaningful security in practice.
4. Key Criteria for Choosing the Best Antivirus Software for Chromebook
When evaluating antivirus options, here are important factors to prioritize:
| Criteria | Why It Matters for Chromebooks |
|---|---|
| Android app compatibility | Only some Chromebooks support Android apps; those that do need well-built Android versions. |
| Web / URL protection | A core function given most threats come via the browser. |
| Scans & file protection | Ability to scan files, downloads, and USB/Cloud-synced files. |
| Lightweight & performance | Antivirus shouldn’t hog resources or slow things down. |
| Automatic updates | Threat definitions must stay current. |
| Extra features | VPN, identity protection, app locker, etc. are nice bonuses. |
| Reputation & independent testing | Choose vendors with good track records and third-party test results. |
In many recent reviews, antivirus providers like TotalAV, Norton, Bitdefender, Malwarebytes, and Surfshark are cited as among the top options for Chromebook protection.
Comparitech suggests that Surfshark One is a strong all-in-one option with antivirus, VPN, and breach monitoring.
Let’s move to specific software options.

7. Tips to Improve Chromebook Security (Beyond Antivirus)
An antivirus tool is only one layer. Here are other strategies you should adopt:
- Use strong, unique passwords (with a password manager).
- Enable two-factor authentication (2FA) on all accounts.
- Use a VPN when on public Wi-Fi (many antivirus suites offer one).
- Be cautious with extensions: only use trusted Chrome extensions and review their permissions.
- Avoid sideloading apps from unknown sources (especially in Play Store or via APK).
- Backup data to secure cloud storage, so if anything happens you can restore.
- Regularly audit installed apps: remove ones you don’t use.
- Enable auto-updates for apps and ChromeOS.
- Educate yourself on phishing and malicious links: no antivirus catches everything.
8. Frequently Asked Questions (FAQ)
Q1: Can a Chromebook get a virus?
Yes—while Chromebooks are less vulnerable than many systems, they can still be targeted by web-based threats, malicious Android apps, phishing attacks, and drive-by downloads. The sandboxing and built-in protections reduce risk, but don’t eliminate it entirely.
Q2: Does antivirus software even work on ChromeOS?
Not in the same way it does on Windows. Because ChromeOS restricts deep system access, antivirus apps typically operate at the Android app level or via browser extensions. They’re more about adding layers of protection (URL filtering, app scanning) than full system defense.
Q3: What is the best free antivirus for Chromebook?
Free-tier versions of Avira and some others are often cited as decent starting options (with limitations). However, for full real-time protection, you often need a paid plan.
Q4: Will antivirus slow down my Chromebook?
A poorly optimized antivirus might cause lag, but many of the top ones are designed to be lightweight. Cloud-based scanning further reduces local impact.
Q5: Can I rely only on built-in ChromeOS security?
You can, and many users do, thanks to sandboxing, verified boot, and automatic updates. But adding an antivirus gives you extra defense against threats that slip through gaps.
9. Conclusion
Finding the best antivirus software for Chromebook is a bit different than for Windows or macOS. Because ChromeOS is built with security-first architecture, antivirus solutions must operate within constraints—mainly via Android apps or browser extensions.
As of current reviews and tests, TotalAV frequently emerges as a strong all-rounder, thanks to its feature set and Android compatibility. Other solid options include Norton, Bitdefender, Malwarebytes, Surfshark One, Avira, and Webroot.
But remember: antivirus is just one piece of your security puzzle. Keep your system and apps up to date, use strong passwords, be cautious of phishing, and use trusted extensions. Combine built-in protections with a good antivirus solution to get closer to a truly secure Chromebook experience.
