Webcam light won't turn off (External webcam)

Maybe the webcam light doesn't turn off because it "froze." To "unfreeze" it, try unplugging the webcam from the computer's USB port and plugging it back it after a couple of minutes. If the light turns on again, it means that either the program you used the webcam with is running in the background or your computer is infected with a virus.

If you haven't turned off your computer for some time, i.e. you put it in the sleep mode when you don't use it, and you are unable to turn off the webcam's light, consider turning your computer off and turning it back on after a couple of minutes.

If the webcam light won't turn off when you browse the Internet, a bad (sometimes malicious) browser extension might be the reason. In this case, removing the browser extension should solve this problem.

Maybe the program itself is buggy, and as a result it can't turn off the webcam. Check if the program manufacturer released an update of the program, which should fix this bug. If an update is available, download it from the program developer's website and apply it.
