Chromebooks run on ChromeOS, which has strong security built in. The system uses sandboxing to isolate apps and verified boot to check for tampering at startup.
While Chromebooks rarely get infected, threats can still slip through malicious browser extensions or Android apps from unknown sources. Phishing attacks can also compromise your device.
You need to know how to scan for viruses on Chromebook to catch potential threats early. This guide shows you practical steps to check your device and remove harmful software.
Regular scanning keeps your Chromebook running smoothly and protects your personal data from unauthorized access.
How To Scan For Viruses On Chromebook?
ChromeOS doesn’t have a built-in antivirus scanner like Windows or macOS. You’ll need to use Android-compatible security apps or manual checks to find malware.
Follow these steps to scan your Chromebook for potential threats.
Update Your ChromeOS
Start by updating your Chromebook to the latest version. ChromeOS updates include security patches that fix known vulnerabilities.
Click the time in the bottom-right corner of your screen. Select the gear icon to open Settings.
Navigate to About ChromeOS and click Check for updates. If an update is available, your Chromebook will download and install it automatically.
Restart your device when prompted to complete the update process.
Review Browser Extensions
Malicious extensions are a common way malware enters Chromebooks. Some Chrome extensions look legitimate but collect your data or display unwanted ads.
Open Chrome and click the three-dot menu in the top-right corner. Select More tools, then Extensions.
Look through your installed extensions carefully. Remove any you don’t recognize or haven’t used recently.
Pay attention to extensions that request excessive permissions or have poor reviews.
Check Android Apps
Android apps on your Chromebook can carry malware if downloaded from unverified sources. Even apps from the Google Play Store occasionally slip through screening.
Click the launcher icon and select All Apps. Right-click any suspicious or unfamiliar app and choose Uninstall.
Remove apps you don’t remember installing or those that behave strangely.
Install Antivirus Software
To scan for viruses on Chromebook properly, you need antivirus software that works with Android. Several reputable options are available through the Google Play Store.
Open the Google Play Store on your Chromebook. Search for antivirus apps like TotalAV, Bitdefender, or Avira.
Download and install your chosen antivirus app. Open the app and complete any initial setup steps.
Some free antivirus options provide basic scanning features without requiring a subscription.
Run a Full System Scan
Once you’ve installed antivirus software, run a complete scan of your Chromebook. This process checks all files and apps for threats.
Open your antivirus app and locate the scan option. Select Full Scan or System Scan from the menu.
The scan may take several minutes depending on how many files you have. Let it complete without interruption.
Review the results when the scan finishes. If threats are found, follow the app’s instructions to quarantine or remove them.
Reset If Necessary
If you suspect serious malware that antivirus software can’t remove, consider a Powerwash. This factory reset removes all local data and restarts your Chromebook fresh.
Back up important files to Google Drive before resetting. Open Settings and search for Powerwash.
Follow the prompts to reset your device. Your Chromebook will restart with a clean ChromeOS installation.
FAQs
Do Chromebooks need antivirus software?
Chromebooks have strong built-in security, but antivirus software adds protection against malicious extensions and Android apps. Extra security measures help catch threats that bypass ChromeOS defenses, especially if you install apps from unknown sources.
How often should I scan my Chromebook for viruses?
Run a full scan monthly if you regularly download files or install new apps. If you only browse trusted websites and rarely install software, scanning every two months is sufficient. Always scan after installing new extensions or apps.
Can Chromebooks get infected through websites?
Yes, visiting compromised websites can lead to infections through malicious downloads or phishing attempts. ChromeOS blocks many threats automatically, but hackers use various methods to bypass security. Stick to trusted websites and avoid clicking suspicious links.
What are signs my Chromebook has malware?
Watch for unexpected pop-ups, browser redirects to unfamiliar sites, or slower performance than usual. Unfamiliar apps appearing without installation or changed browser settings also indicate potential malware. Strange battery drain can signal background malicious processes.
Is a Powerwash safe for removing viruses?
Powerwash removes all local files and resets ChromeOS to factory settings, effectively eliminating malware. However, back up important files first since data safety requires proper preparation. Synced Chrome data remains accessible after reset through your Google account.
