Avira Antivirus Install and Uninstall (PowerShell)


This article will serve as an informative guide and give you a clear understanding of how to perform silent or interactive installs and uninstalls of Avira Antivirus using the Powershell App Deployment Toolkit. The PowerShell App Deployment Toolkit can be used to replace your WiseScript, VBScript and Batch wrapper scripts with one versatile, re-usable and extensible tool. This tool is an absolute must for Microsoft Endpoint Manager Configuration Manager (MEMCM) / (SCCM) Administrators or anyone who is responsible for packaging and deploying software.

How to Install Avira Antivirus Using the PowerShell App Deployment Toolkit

  1. Download the Powershell App Deployment Toolkit 3.8.4:
  2. Download the zip file to a folder created at (C:\Downloads)
  3. Open Windows PowerShell by Right-Clicking on Windows PowerShell and selecting Run as Administrator
  4. Enter the following command to remove the Zone.Identifier:
    • Unblock-File -Path C:\Downloads\PSAppDeployToolkit_v3.8.4.zip
  5. Enter the following command to extract the contents of the zip file:
    • Expand-Archive -Path C:\Downloads\PSAppDeployToolkit_v3.8.4.zip -DestinationPath C:\Downloads\PADT
  6. Enter the following commands to copy the AppDeployToolkit & Files folders to “C:\Downloads\AviraAntivirus”:
    • Copy-Item -Path "C:\Downloads\PADT\Toolkit\AppDeployToolkit" -Destination "C:\Downloads\AviraAntivirus\AppDeployToolkit" -Recurse
    • Copy-Item -Path "C:\Downloads\PADT\Toolkit\Files" -Destination "C:\Downloads\AviraAntivirus\Files"

You should now see the AppDeploymentToolkit folder with files & the empty Files folder at “C:\Downloads\AviraAntivirus”

Next we’ll want to download the EXE installer for Avira Antivirus and create the setup.inf configuration file.

.SYNOPSIS
	This script performs the installation or uninstallation of Avira Antivirus.
	# LICENSE #
	PowerShell App Deployment Toolkit - Provides a set of functions to perform common application deployment tasks on Windows.
	Copyright (C) 2017 - Sean Lillis, Dan Cunningham, Muhammad Mashwani, Aman Motazedian.
	This program is free software: you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation, either version 3 of the License, or any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
	You should have received a copy of the GNU Lesser General Public License along with this program. If not, see <http://www.gnu.org/licenses/>.
.DESCRIPTION
	The script is provided as a template to perform an install or uninstall of an application(s).
	The script either performs an "Install" deployment type or an "Uninstall" deployment type.
	The install deployment type is broken down into 3 main sections/phases: Pre-Install, Install, and Post-Install.
	The script dot-sources the AppDeployToolkitMain.ps1 script which contains the logic and functions required to install or uninstall an application.
.PARAMETER DeploymentType
	The type of deployment to perform. Default is: Install.
.PARAMETER DeployMode
	Specifies whether the installation should be run in Interactive, Silent, or NonInteractive mode. Default is: Interactive. Options: Interactive = Shows dialogs, Silent = No dialogs, NonInteractive = Very silent, i.e. no blocking apps. NonInteractive mode is automatically set if it is detected that the process is not user interactive.
.PARAMETER AllowRebootPassThru
	Allows the 3010 return code (requires restart) to be passed back to the parent process (e.g. SCCM) if detected from an installation. If 3010 is passed back to SCCM, a reboot prompt will be triggered.
.PARAMETER TerminalServerMode
	Changes to "user install mode" and back to "user execute mode" for installing/uninstalling applications for Remote Destkop Session Hosts/Citrix servers.
.PARAMETER DisableLogging
	Disables logging to file for the script. Default is: $false.
.EXAMPLE
    PowerShell.exe .\Deploy-AviraAntivirus.ps1 -DeploymentType "Install" -DeployMode "NonInteractive"
.EXAMPLE
    PowerShell.exe .\Deploy-AviraAntivirus.ps1 -DeploymentType "Install" -DeployMode "Silent"
.EXAMPLE
    PowerShell.exe .\Deploy-AviraAntivirus.ps1 -DeploymentType "Install" -DeployMode "Interactive"
.EXAMPLE
    PowerShell.exe .\Deploy-AviraAntivirus.ps1 -DeploymentType "Uninstall" -DeployMode "NonInteractive"
