Do Chromebooks need antivirus?
Not in the traditional sense. ChromeOS itself is very hard for malware to infect. You benefit from extra protection if you install many Android apps, sideload apps, or want help spotting phishing and scam sites. Keeping ChromeOS updated and only installing apps from Google Play does most of the work.
How to install antivirus on a Chromebook
- Open Settings, then Apps, and make sure Google Play Store is turned on.
- Open the Play Store and search for the antivirus, for example Bitdefender Antivirus Free.
- Select Install and wait for it to finish.
- Open the app, grant the permissions it asks for and run the first scan.
- Optional: add the vendor’s browser extension, such as Avira Browser Safety, from the Chrome Web Store.
Free vs paid Chromebook antivirus
| Free antivirus | Paid antivirus | |
|---|---|---|
| App scanning | Yes | Yes |
| Real-time protection | Sometimes | Yes |
| Phishing and web protection | Limited | Yes |
| Ads or upgrade prompts | Often | No |
| Support | Self-help | Customer support |
For most Chromebook owners a good free app is enough. If you want protection across Windows, Mac and phones too, see our full list of the best antivirus software.
Frequently asked questions
Can Chromebooks get viruses?
Traditional viruses are extremely rare on ChromeOS. Malicious Android apps, browser extensions and phishing sites are the main risks.
Is Google’s built-in protection enough?
For careful users, ChromeOS updates, Google Play Protect and Chrome’s Safe Browsing cover a lot. Antivirus adds a second opinion on apps and extra phishing protection.
Will antivirus slow down my Chromebook?
Lightweight apps such as Bitdefender Free and ESET have very little impact. Avoid installing more than one.
Final thoughts
Start with Bitdefender Antivirus Free or Avira Free Security for free protection, keep ChromeOS updated, and only install apps from Google Play. Upgrade to Norton 360 if you want web protection, scam detection and a VPN across all your devices.
