Download Full and Free Trial versions

  • The Full and Free Trial download files are the same. "Activate" the software during installation with a valid licence key for a paid licence, or an email address for a 30 day trial.
  • We strongly recommend you UNINSTALL any existing security software before installing ESET as they can sometimes clash.
  • IMPORTANT! 32-bit or 64-bit? If you're unsure of your PC's operating system just use the Live Installer option or call our helpdesk.
  • The Live Installer will download a small application which will check your PC's Operating System and then download and install the correct version.
