  1. Click Continue in the Live Grid window (the Live Grid Early Warning System submits new threats to ESET's labs and provides feedback that improves protection. Deselect the check box next to Enable Live Grid Early Warning System to disable this functionality).
  1. The next step of the installation process is to configure detection of Potentially unwanted applications (what is a potentially unwanted application?). Such programs are not necessarily malicious, but can negatively affect the behavior of your operating system. These applications are often bundled with other programs and may be difficult to notice during the installation process. Although these applications usually display a notification during installation, they can easily be installed without your consent. Select one of the options and click Continue.
