In addition, if a UDP packet is sent to the system port 1900, and the address of the "Location" field is pointed to the charging port of another system, it may cause the system to enter an infinite loop, consuming all the resources of the system (required when installing hardware) Manually turned on).

3.Messenger: Commonly known as messenger service, computer users can use it for data exchange in the LAN (transfer Net Send and Alerter service messages between client and server, this service has nothing to do with Windows Messenger. If the service Stop, Alerter messages will not be transmitted). This is a dangerous and annoying service.
