(My company's current network is sometimes connected to the Internet, sometimes not, and the PING gateway is also not PING, intermittently, using ARP-A to check the ARP table, there is an IP address that does not exist, and the corresponding MAC address of this address is full 00-00 -00-00-00-00, if you check with ARP-A at one time, this IP address will become another IP address that does not exist. Check it becomes 192.168.1.8900-00-00-00-00-00, my problem now is that I can't find which machine has this virus
