12 Best Antivirus For Chromebook In 2024 | Free & Paid

Launched in 2011, Chromebook has become one of the most popular devices running Android and full-fledged Linux applications. With about 30 million units sold every year, Chromebook accounts for 11% of the total PC market.

But how safe are these devices?

Google provides multiple-layered security against various malware. This includes data encryption, sandboxing during malware attacks, recovery mode, automatic updates, and verified boot during system startup. While all these functions are necessary, they are not enough to keep your device safe from external attacks.

Chromebooks are prone to malicious scripts, such as spyware, trackers, and phishing scams. In fact, there are plenty of harmful apps on Chrome Web Stores and Google Play that can infect your device and compromise your account.

Phishing attacks and browser hijackers, for example, can trick users into sharing personal data and installing scripts on their devices. Once the script is installed, attackers can easily steal sensitive data such as login details and financial information. And the worst thing is users don’t realize they are being spied upon until their device starts slowing down.

According to Kaspersky, more than 550,000 new pieces of malware are identified daily and four organizations fall victim to ransomware every minute. Google’s Transparency Report shows that about 2.2 million websites are “dangerous for safe browsing.” The majority of those are phishing sites.

A good antivirus tool can keep you safe from all these attacks.

Below, we have listed some of the best antivirus tools for Chromebook that offer an additional layer of security while streaming, browsing, and downloading content. They protect your existing files and data and keep your device as clean as possible.

Lookout can be easily integrated into your existing security and endpoint management solutions. It focuses on three types of threats:

  • Network-based threats: It effectively detects man-in-the-middle attacks, ensuring attackers do not intercept the network traffic.
  • Phishing threats: It protects you against malicious websites that try to run harmful scripts when you visit them.
  • Application threats: It detects infected Android apps installed on Chromebooks and warns you if there are chances of losing data.

Lookout gives you access to a cloud-based admin console that shows you the overall health of your device. It continuously monitors the Chrome OS, assigns a level of risk, and shares this data with Google Cloud Identity. Based on how severe the risk is, it may block access to all unknown parties until the threat on the Chromebook is removed.

The platform has gathered security data from about 200 million devices worldwide and over 120 million applications, with nearly 100,000 new apps examined every day. To process such massive volumes of data, it uses artificial intelligence models. More specifically, it employs machine learning algorithms to identify the complex patterns that indicate risk.

More To Know

How to choose the best antivirus for your Chromebook?

Selecting an antivirus tool depends on how much protection you need. If you just need a basic defense against known malware, install a free version of a highly-rated antivirus engine.
