When certain LG monitors are connected to a PC running Windows 11, Windows Update reportedly installs an LG driver update and a management app called ‘ LG Monitor App Installer ‘ on the PC. This app doesn’t contain any special features, but it displays pop-up advertisements for other LG apps and McAfee.

The YouTube channel ‘ Gamers Nexus ,’ with 2.63 million subscribers, purchased an LG gaming monitor, the ‘ LG UltraGear 34GX900A-B ,’ to investigate this phenomenon. When connected to Windows 11 and used, they reported that multiple pop-up ads appeared. According to Gamers Nexus, pop-up ads for LG apps such as LG Switch, LG Calibration Studio, LG Dual Controller, and LG Channels also appeared, but they reported that most of them were McAfee pop-up ads.

Following a video from Gamers Nexus, Microsoft announced it would remove McAfee pop-up ads from the LG Monitor App Installer. Pavan Davrli, Executive Vice President of Windows Devices, posted, ‘We have reached out to the LG team and successfully secured their agreement to first disable McAfee pop-up ads in the app. We appreciate LG’s cooperation in our shared goal of providing a better experience for both our customers. We will continue to work with our ecosystem partners to improve in this area.’

Thanks again for bringing this to our attention. We’ve connected with the team at LG and as an immediate next step, they have agreed to disable the McAfee pop-up from their app. We appreciate LG working with us toward a shared goal of a better experience for our mutual customers.…
