Adding or removing Avast Antivirus program components

In Avast Antivirus, various program components contribute to the overall protection of your PC. Certain components are installed by default while others can be added during advanced installation. You can manually install or uninstall components at any time, however, we do not recommend uninstalling components unless necessary for troubleshooting purposes.

Add or remove program components

Manage individual program components in the Avast user interface:

  1. Open the Avast user interface and go to Settings ▸ Components.
  2. Follow the relevant step depending on whether you want to add or remove a component:
    • To install a component:

      Click the Install Component link next to the component that you want to add (for example, Anti-spam).
    • To uninstall a component:

      Click the downward facing arrow next to the component that you want to remove (for example, Real Site), click Uninstall Component, then click OK to confirm the uninstallation.
  3. Restart your PC, if required.

Manage individual program components in the Avast Setup wizard:

  1. Log into Windows as an administrator and ensure no other programs are running.
  2. Access the Avast Setup wizard via your Control Panel.
  3. When the Avast Setup wizard appears, click Modify. A list of recommended program components for your edition of Avast appears.
  4. Select or deselect the components you want to add or remove, then click Change.
  5. When the update is complete, click Done and, if required, restart your PC.
