You can do a few things to check whether your webcam has been compromised if you have ever looked into its lens and wondered, "What if someone's watching me right now?
Don't panic if the warning appears, however; it can also mean that a different program on your computer is using the webcam and causing the error.
Click "Start," "Control Panel." Choose "Add/Remove Programs," then "Uninstall Programs." Remove any application or software package that has a webcam feature, except your primary webcam utility.
Your webcam, whether it's built into your computer's monitor or attached via a USB cable, can be used by streaming software to transmit a live video from your current location to a remote location, such as a video streaming website or another user's computer.
Though webcams serve a valid purpose — communicating with users in a different location — they can also be a source of paranoia.
This may include chatting software and video-making programs.
