What is mosquitto.exe?

Mosquitto.exe is an executable file associated with the software Eclipse Mosquitto, an open-source message broker that implements the MQTT protocol. MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol for small sensors and mobile devices, optimized for high-latency or unreliable networks. This software is developed by the Eclipse Foundation.

The primary use of Mosquitto.exe is to enable IoT (Internet of Things) functionality. It is often used in conjunction with software like TeamViewer HostIoT to facilitate communication between various IoT devices. It is typically found in the directory C:\Program Files\mosquitto.

Whether Mosquitto.exe should be removed or not depends on its usage. If you are using IoT devices and require the MQTT protocol for communication, then it is necessary to keep it. If you are not using any IoT devices or software that requires the MQTT protocol, it may not be necessary.

Any executable file should be scanned for viruses or malware to ensure it's not a threat to your system. If your antivirus software flags Mosquitto.exe as a threat, it should be removed.
