LG Monitors Reportedly Install Adware-Like App Silently via Windows Update
Certain LG monitors connected to Windows PCs are reportedly triggering Windows Update to automatically install the LG Monitor App Installer. This application then runs at startup and frequently displays trial promotions for McAfee security software, according to reports. The installation process reportedly occurs without a consent prompt or user approval. Gamers Nexus reproduced this behavior, observing the app's installation and subsequent display of McAfee promotions in 31 out of 32 system boots. This issue is not limited to new monitors, with reports indicating it affects displays purchased years ago, and user complaints date back to at least 2024.
Connecting certain LG monitors to Windows PCs can reportedly lead to Windows Update automatically installing an application described as adware-like. The LG Monitor App Installer runs upon system startup and repeatedly promotes McAfee trial subscriptions.
Gamers Nexus reproduced this behavior after receiving multiple reports from monitor owners. Their tests with an LG UltraGear 34GX900A-B showed Windows Update first installed LG extension and software component packages, followed by the LG Monitor App Installer one minute later, as recorded by Windows Reliability Monitor. The installation did not require user approval or display a consent prompt.
Further testing by Gamers Nexus across 32 consecutive system boots revealed that the application displayed a McAfee promotion during 31 of these boots. The remaining boot promoted one of LG's own monitor utilities. The McAfee popup offered a 30-day trial that would convert into a paid subscription.
The issue appears to affect more than just newly purchased displays. Gamers Nexus also observed the popup on an LG UltraFine 32UN880-B that was acquired three years prior. User complaints regarding the LG Monitor App Installer have been noted since at least 2024, with a recent increase in reports suggesting that a wider range of models may now be impacted.
According to Slashdot, the behavior involves the silent installation and promotion of third-party software without explicit user consent.
