Update: We reached out to LG for a statement, and it has denied claims of auto McAfee installations, stating: "LG Electronics reiterates that McAfee is not installed automatically and is never installed without the user’s explicit consent. The LG Monitor App Installer is distributed through Microsoft’s official Windows distribution process, which included McAfee as an option.
"McAfee will be installed only if a user actively chooses to proceed with the installation and provides consent. Under no circumstances is McAfee installed automatically or without user authorization. The LG Monitor App Installer does not access, collect, or transmit any customer personal data."
