A HOT POTATO: Adware is usually associated with pre-built PCs and dubious free downloads, but some users recently discovered that even legitimate monitors can quietly install apps that display pop-ups without permission. Fixing the issue seems to require changing local group policy settings or, in extreme cases, disabling the Microsoft Store altogether.

Redditor "Mags_Smash" recently complained about seeing McAfee pop-up ads on his PC despite never having installed the antivirus suite. He eventually traced the ads back to another app that his new LG monitor had installed without his knowledge.

After connecting one LG UltraGear 27GP83B monitor and two 27GN800s, Mags_Smash found that at least one of the panels had installed an "LG Monitor App Installer" via the Microsoft Store and Windows Update. The application shows up under the name "9PM9N6F47JB8-LGElectronics.LGMonitorApp" in Reliability Monitor, and Event Viewer logged its successful installation.

Several others reported the same problem after coming across the discussion, and some found their own systems were affected once they went looking. Others confirmed similar behavior with Dell and Alienware monitors, comparing it to how Asus motherboards automatically install the company's Armory Crate software.
