Yes, Chromebooks can get infected by viruses and malware but it is extremely rare thanks to their multilayered security architecture. While Chrome OS has robust builtin protections, Chromebooks are still vulnerable to threats like phishing, malicious extensions and compromised Android apps.
Having a reputable antivirus provides an extra layer of defense for maximum safety. In this comprehensive guide, we will explore Chromebook security, risks, the best antivirus software and provide tips to keep your device infection-free.
How Secure is Chrome OS?
Chromebooks run Chrome OS, an operating system designed with security as a top priority. Multiple defenses work together to create an ultra-secure environment that blocks most traditional virus attacks:
Automatic Updates
Chrome OS is constantly improved by Google with security patches and feature updates. These are immediately pushed to all Chromebook users automatically. This ensures you are always running the most secure Chrome OS version without any effort on your part.
According to research from antivirus testing lab AV-Test, over 200 updates were released in 2021 to fix security flaws in Chrome OS. Staying updated is key to preventing infection attempts using older vulnerabilities.
Sandboxing
A sandbox isolates each app and browser tab into its own enclosed space. Even if malicious code somehow finds its way onto your Chromebook, it cannot escape the sandbox to infect other parts of the system.
Viruses are prevented from spreading beyond the app level. According to Google, this innovative sandboxing technique makes Chrome OS much more secure compared to traditional operating systems.
Verified Boot
Every time you start your Chromebook, it performs a self-check called Verified Boot. This scans for any system corruption, compromised settings or tampering with the operating system files.
If any issues are detected, Chrome OS will automatically repair itself to regain its secure state. This prevents any persistent infections from surviving restarts.
Data Encryption
Your local data like downloads, cookies and browsing history is encrypted by default using tamper-resistant hardware. This makes it extremely difficult for viruses to access and steal sensitive personal information.
Recovery Mode
As a last resort, you can restore your Chromebook to a clean factory settings state in seconds using Recovery Mode. Just press Ctrl + Alt + Shift + R during startup. This will wipe your system and remove any advanced infections.
According to website CVE Details, Chrome OS only has 46 known vulnerabilities currently, compared to 588 for Windows 11 and 3,101 for Mac OS X. The layered security of Chromebooks makes them highly resistant to viruses and cyber attacks.
Security Risks Facing Chromebooks
While Chromebooks provide much stronger defenses compared to Windows PCs and Mac devices, they are not completely immune to infections. Some threats can still break through if you are not careful:
Malicious Websites
Websites infected with malware are a prime threat vector. Browsing to insecure or compromised sites allows cybercriminals to launch "drive-by" attacks to install viruses, hijackers and spyware.
While Google Chrome has good protection against malicious sites, an infected website could still slip through and attack an underlying vulnerability in Chrome OS.
Fake Browser Extensions
Browser extensions require access to read and modify web page content in order to work. However malicious extensions can abuse this privilege to steal data or inject malware into pages you visit.
Such extensions may also change browser settings like default search engine without your permission. Though Google vets extensions submitted to the Chrome Web Store, sometimes fake extensions using names of legitimate apps get approved.
Compromised Android Apps
Chromebooks allow installing Android apps from the Google Play Store for access to millions of mobile apps. While the Play Store has security checks, occasionally infected apps make it past Google‘s screening processes.
Researchers have found malware-laced apps with over 100,000 downloads in the Play Store before being caught. Also, downloading Android apps from third-party stores greatly increases infection risks.
Phishing & Social Engineering
Despite strong technical safeguards, users themselves can be the weakest link in security. A well-crafted phishing email or social media scam could fool someone into downloading malware, entering login credentials on fake sites or sharing sensitive personal information.
Being vigilant is key – Chromebooks cannot protect against poor judgement. Cybercriminals are experts at psychological manipulation tactics.
Vulnerabilities & Exploits
No software is perfect. Like all operating systems, Chrome OS has some vulnerabilities that hackers could exploit to run malware. In 2021, Google patched several "zero-day" flaws being used to attack Chromebooks.
But since the source code for Chrome OS is public, Google‘s security engineers are quick to find and fix any holes. Updates roll out in days compared to the months it often takes other vendors.
While Chromebooks have excellent defense-in-depth, exercising caution is still necessary when browsing the web and installing apps.
How to Check for Malware on a Chromebook
It‘s easy to inspect your Chromebook for any infections:
Review Browser Extensions
Check for any unknown, suspicious or recently installed Chrome extensions. Malware authors often disguise extension names to seem legitimate. Look for typos, generic names or anything out of the ordinary.
- Click the puzzle icon in Chrome to open the Extensions menu
- Review the list and research any unfamiliar extensions
- Remove any unwanted or questionable extensions
Verify Android Apps
Scan through your installed Play Store apps and uninstall anything that seems dubious. Stick to downloading apps only from the official Google Play store and avoid sideloading from unknown sources.
- Open the Play Store app
- Go to Manage Apps & Devices -> Manage
- Review the apps – watch for generic names or sketchy descriptions
- Uninstall any unwanted apps
Also check for signs of infection like slower performance, crashes or unexpected popups. If issues persist after removing suspicious extensions and apps, run a full antivirus scan.
