Components

Manage these settings from: SettingsComponents

The Components screen allows you to manage all features included in your version of Avast Antivirus. These features are divided into three sections labeled as Security, Privacy, and Performance.

Some components may be inactive in your version of Avast. This may be because the components were not installed during installation of Avast Antivirus, or because they are not included in your program version by default.

Note: All security components are available in Avast Premier, however some Privacy and Performance components such as SecureLine VPN and Passwords, are available in all versions of Avast only as extra paid features.

Manage components

Depending on each component, you can perform the following actions:

  • Customize a component:
    • Click Customize next to a component to adjust its settings.
  • Enable/disable a component:
    • To enable a component, click the OFF slider so that it changes to ON.
    • To disable a component, click the ON slider so that it changes to OFF. For the crucial security components such as Shields and Firewall, select how long you want a component to be temporarily disabled to minimize risk.
  • Install/uninstall a component:
    • Click Install Component next to the component you want to use (some components are not installed by default). Some components may require you to restart your PC.
    • Click the down arrow to expand the panel of the component you want to uninstall. Then, click Uninstall and OK to confirm.

Note: We strongly recommend you keep all crucial security components, such as Shields and Firewall, installed and enabled to ensure your maximum protection. We do not recommend you turn off these components indefinitely by selecting the Stop permanently option.
