Avast can block Carbonite from installing and operating normally.

This article applies to:

Carbonite Plans Products Platforms
Basic, Plus, Prime, Core, Power and Ultimate (Not sure?) Safe and Safe Pro (Not sure?) Windows


  1. Right-click the Avast icon in your Windows notification area, and click Open Avast User Interface.
  2. Click Menu to the top right of the user interface then select Settings in the window that appears.
  3. Under General, click Exceptions to expand this section.
  4. Select the File paths tab
    • Click the Browse button next to a blank line.
  5. Select the individual files and folders in the following locations to be excluded from the Avast scans:
    • The Carbonite Installer
      • Typically named CarboniteSetup-personal-client.exe
      • Saved by default in C:\Users\[username]\Downloads\
        Where [username] is the folder name of the Windows user that downloaded the installer.
    • The Carbonite Install Directories
      • C:\Program Files\Carbonite\Carbonite Backup\ (32-bit Windows)
      • C:\Program Files (x86)\Carbonite\Carbonite Backup\ (64-bit Windows only)
      • C:\Documents and Settings\All Users\Application Data\Carbonite\Carbonite Backup\ (Windows XP)
      • C:\ProgramData\Carbonite\Carbonite Backup\ (Windows Vista, Windows 7, Windows 8, Windows 10)

    Use the + (plus) signs to navigate to the correct locations, ensuring that there is a check mark next to the Carbonite Backup folder for each location you add.

    Note: If the Carbonite directories above do not exist after a failed installation attempt, the applicable folders can be created manually and then exceptions set within Avast. As an example, on a 64-bit Windows 10 computer, create a Carbonite subfolder within C:\Program Files\, C:\Program Files (x86)\, and C:\ProgramData\, then create a Carbonite Backup folder within each of the Carbonite subfolders.

  6. Click OK when you have finished selecting locations to be excluded and Avast will automatically add each location as a separate line on the Exceptions list.
  7. Click OK at the bottom of the Settings window and close the Avast User Interface.


Avast may continue to block Carbonite even after exceptions are configured. This issue is specific to Avast. If you experience this issue, we recommend contacting Avast customer care for further assistance. Their contact number is 1-855-746-4118.
