Why and How to Turn Off Antivirus on Mac Computers


In today’s connected world, computer security is more important than ever. We rely on our devices to store sensitive information, conduct financial transactions, and access critical systems. This makes them an attractive target for cybercriminals seeking to steal data or install malware like viruses or ransomware. While Windows PCs have historically been most vulnerable to attacks, Mac computers are not immune. That’s why most Mac users employ antivirus software as one layer of protection.

However, antivirus tools utilize system resources to continuously scan for threats. This can reduce performance and battery life. Additionally, Apple has engineered multiple native security protections into macOS, making some question the necessity of third-party antivirus. So when can you safely turn off or uninstall antivirus on a Mac? Let’s take a closer look.

The Strengths Behind Chrome OS Security

Chromebooks come equipped with layers of built-in protections that drastically minimize the need for third-party antivirus apps. Even though Chromebooks have built-in security, you still need effective virus protection for Chromebooks. Let’s look at some key reasons why antivirus is largely redundant on properly updated Chrome OS devices:

Sandboxing: Chrome OS utilizes advanced sandboxing of processes and applications, meaning they each run restricted in their own environments isolated from critical system components. This containment prevents malware or crashes within an app from spreading across your device.

Seamless and Automatic Updates: Chromebooks install system and security updates seamlessly in the background as soon as they become available. This means potential security vulnerabilities get patched without you needing to manually install updates or antivirus database updates.

Reputable App Store with Vetting: The Google Play Store available on Chromebooks vets and verifies apps, acting as a gatekeeper against malware making its way onto your system. Downloading apps from outside this trusted source invites more risk.

Data Encryption: Chrome OS employs end-to-end data encryption for crucial user data, preventing access in the case of device theft or loss while also securing backups stored in the cloud.

Verified Boot Process: Each time a Chromebook starts up, it self-verifies the integrity of the operating system through a read-only boot process. If any components have been tampered with or corrupted, it will repair itself from a clean backup state.

Limited Owner/Admin Privileges: Unlike other operating systems, Chrome OS restricts access privileges even for the owner of the device. This constraint drastically limits the potential impact and changeability of any malware that evades other protections. Users essentially access Chromebooks as guests without admin powers.

Bonus Protection: The Best Antivirus Apps for Chromebooks

While Chrome OS’s multi-layered security renders antivirus unnecessary for most users, some may still wish to take the extra precaution, especially those accessing riskier websites and content. These top-rated Chrome antivirus apps provide robust real-time protection:

  • Avast Antivirus for Chrome:  Offers automatic scanning and manual scanning options to detect malware.
  • Bitdefender Virus Scanner: Includes autopilot mode for automatic scanning along with on-demand custom scanning. Highly rated.
  • Norton 360 Deluxe: More full-featured antivirus protection, including dark web monitoring and a no-logs VPN.

While paid antivirus apps offer robust scanning and threat detection, the free built-in protections still make their high subscription costs unnecessary for most general-use Chromebook owners.

When to Turn Off Chromebook Antivirus Protection

The streamlined antivirus apps available for Chrome OS use minimal system resources when running scans in the background. However, users may still wish to manage and turn off antivirus protection occasionally for better performance, including when:

  • Playing games or using other graphics-intensive programs
  • Using performance-taxing creative apps like video editors
  • Noticing sluggishness or reduced battery life
  • Temporarily troubleshooting compatibility issues with antivirus software

To disable antivirus apps on Chrome OS:

  1. Click the system tray icon for your antivirus program.
  2. Select “Disable” or “Turn Off”, depending on the app.
  3. Toggle the protection back on when desired for renewed scanning and threat detection.

It’s perfectly fine for the majority of general users to run their Chromebook without any third-party antivirus app, given the unobtrusive nature of Chrome OS’s security. But those opting to use one can easily manage protection as needed.

Do You Need Antivirus on a Chromebook?

  • Built-in security: Chrome OS has end-to-end encryption, auto-updates, verified boot protection, sandboxing, and other features, eliminating the need for antivirus software.
  • Low risk: The tightly controlled Google Play Store, read-only system processes, and limited user privileges prevent malware installation & impact.
  • Bonus layer: Optional antivirus apps like Avast, Bitdefender, and Norton 360 provide robust additional protection for risky browsing.
  • Performance control: Antivirus scans can be temporarily disabled to reduce sluggishness without compromising security.


So, while it’s ultimately up to you, the vast majority of Chromebook owners gain adequate peace of mind by sticking with the robust built-in protections for day-to-day browsing rather than installing intensive antivirus. Only those accessing riskier content may need the extra security layer. But when in doubt, Chrome OS still has you covered with the latest automatic security reinforcements.
