Plug in an LG Monitor and Windows Quietly Installs Software That Sells You Antivirus

- LG monitors, Windows Update, hardware-paired app auto-install
Plug in an LG monitor, and Windows Update quietly installs software on your PC without asking. No prompt, no notification, no consent – just an app appearing on a machine you own, loaded with something you never asked for. This isn’t a bug. It’s a delivery system Microsoft built and LG is now using to sell you antivirus.
The monitor that installs itself
Connect a new LG UltraGear monitor to a Windows 11 machine for the first time and, in the background, Windows Update reaches out and installs the “LG Monitor App Installer” along with driver updates. Gamers Nexus caught it happening on their own hardware and confirmed the behavior has been hitting a lot of people. The machine doesn’t ask. There’s no permission pop-up and no notification. The installer simply shows up, because Windows decided your new screen came with software you never requested.
The app itself is thin. It isn’t a real utility you’d open to adjust your panel. Instead, it’s a doorway that points at LG’s other apps and, prominently, at McAfee antivirus – pushing ad notifications onto your screen for software you never asked to install.
The Windows feature that makes it legal
Microsoft is not an innocent bystander here. Windows includes a mechanism that lets hardware makers pair an app to a device, so the software auto-installs the moment the hardware shows up on your system. Microsoft’s own developer documentation even warns that the automatic installation “does not provide a notification to the user when the app is installed.” In other words, the silence isn’t an accident. It’s a designed-in feature of the system.
LG leaned on that feature, and Microsoft let it. When pressed, LG pointed out that it was using a legitimate Windows capability and that it hadn’t actually installed the full antivirus package – just an ad for it. Technically true, and completely beside the point. The point is that the one channel you trust to patch your PC securely, Windows Update, is being rented out as an advertising delivery network.
Why this is spyware-adjacent
The story doesn’t stop at a pop-up ad. Gamers Nexus frames the broader concern around LG’s ecosystem, including data collection and the app traffic flowing off the devices. When a monitor manufacturer can push software onto your computer silently, and that software can phone home, you’re no longer in control of your own machine. Every LG product you connect becomes another doorway LG holds a key to. Combined with the telemetry-style concerns raised around LG’s TVs and displays, the pattern is familiar: the hardware you paid for is now a channel for ads and data collection you never agreed to.
Microsoft only stepped in after the backlash got loud, with reports that a Microsoft executive reached out and LG agreed to dial back the unwanted pop-ups. But the underlying mechanism is untouched. The capability to silently install a partner’s adware remains in Windows, waiting for the next company to use it.
The receipt
- The scam: Connecting an LG monitor silently installs an adware-like app through Windows Update, pushing McAfee ads onto your screen without consent.
- The mechanism: Windows’ hardware-paired app auto-install feature, which Microsoft designed to skip any notification to the user.
- Why it’s still running: The silent install channel stays in Windows, and LG only stopped the loudest pop-ups after public backlash – the delivery system remains for the next partner.
- The fix that’s missing: Auto-installed third-party apps should require explicit user consent, and Windows Update should never be a vehicle for advertising or companion software.
This is a real, widely-documented problem. The video below walks through it.
