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.

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 your Desktop (once the download has completed, you may be prompted to click Run and begin the installation process. If the installer does not run automatically, navigate to your Desktop or wherever you saved the downloaded file and double-click it to open). When you are ready, continue to part III.
