McAfee cannot be installed directly on most smart TVs (Samsung, LG, Sony, etc.) — they run proprietary operating systems that don’t support antivirus apps. However, you can protect your smart TV by securing the router it connects to and isolating it on a guest Wi-Fi network.

Key Points
- McAfee cannot be installed on Samsung, LG, Sony or other smart TV operating systems
- Smart TVs are vulnerable to: compromised apps, DNS hijacking, and network-based attacks
- Best protection: connect smart TVs to a separate guest Wi-Fi network (most modern routers support this)
- This isolates your TV from your main network where PCs and phones operate
- Change your smart TV’s default settings: disable diagnostic/data sharing where possible
- Keep smart TV firmware updated via Settings → About → Software Update
- Only install apps from the official TV app store — avoid sideloading APKs
