I. Uninstall other antivirus software

You must uninstall any previously installed antivirus software from your system before installing your ESET product (uninstallers for common antivirus software). When you are finished, continue to part II to install your product.

II. Download the ESET Live Installer or insert CD

If you have a CD, insert the CD into your computer (if the installation does not begin automatically, click Start → Computer and double-click the ESET   disc icon) and proceed to part II. If you do not have a functioning CD drive, follow the steps below to download your product:

  1. North American customers: Download ESET Live Installer

    Customers outside of North America: Download ESET Live Installer
  2. Click Save when prompted and save the file to a newly created folder (once the download has completed, you may be prompted to click Run and begin the installation process. Do not install from folders like Downloads, Temp or Desktop. If the installer does not run automatically, navigate to a newly created folder or wherever you saved the downloaded file and double-click it to open). When you are ready, continue to part III.

III. Install ESET NOD32 Antivirus

  1. In the Install ESET NOD32 Antivirus screen, click Continue.
