Microphone monitor allows Bitdefender to detect different applications or web pages that want to grab microphone access and record sound for different purposes such as blackmail or extortion.
Rogue apps may access your built-in microphone silently or in the background without your consent. To make you aware of potential malicious exploits, Bitdefender Microphone monitor will give you notice of such events. This way, no app will be able to gain access to your microphone without you being in charge.
