I am also a user of Huazhong Securities. I suspect that this is a virus called Trojan Backdoor. The grey pigeon (commander) attacked the server of Huazhong Securities. Please don't repeat the connection. If more genuine antivirus software is installed in your computer, it may be stopped. If not, your computer must be poisoned, because this virus will automatically attack your computer n times every time you connect to the original main station, and the IP address keeps changing. I think there is nothing Huazhong Securities can do at present. ! ! !
