Installing Antivirus

This Article Applies to:

  • Essential/Premium/Ultimate Business Security
  • Small Office Protection

For unmanaged Essential/Premium/Ultimate Business Security and Small Office Protection, you can download the Essential/Premium/Ultimate Business Security installer from and the Small Office Protection installer from here. For Essential/Premium/Ultimate Business Security, click on the Business tab and select either the Online or Offline installer for the Antivirus version you have. When the installer is downloaded, you can run it on the device you would like to install Antivirus on.

If you select the Online installer, the other services will be downloaded upon installation of the Antivirus agent. This option is not recommended if you are installing Antivirus on multiple devices at the same, as each machine will individually contact Avast servers to download the other services. 

Customizing Installation

  1. Copy the installer file to a location accessible by the end device
  2. Double-click on the installer file to run it
  3. If asked to allow the application to make changes to your device, click Yes
  4. Click Customize, then do one of the following:
    • Select Recommended protection to install all components
    • Select Minimal protection to install only File, Web, and Mail Shield
    • Select Custom protection so you can check and uncheck the specific components you would like to install. For information on which components are not recommended in a Business environment, see Recommended Components for Servers and Workstations.
  5. Click Install and wait while Essential/Premium/Ultimate Business Security is installed on your device
  6. When prompted, restart the device

Once you have installed Antivirus on your device, be sure to activate your subscription following the information in Activating Licenses.

Installing with a Logon Script

You can install Essential/Premium/Ultimate Business Security as a logon script, as long as you change the file location to reflect the location and name of the install file on your network (\\server\install\avast_business_antivirus_setup.exe).

If you are not familiar with how to use a logon script with your domain, search the Microsoft web site for your domain controller's OS and how to use logon scripts. This article details how to use logon scripts.
