Hi, I have a basic question here. I have some AT systems running during the trading hour and checked the operating situation of it from time to time . But once when I approached to check the system, I found my computer machine has rebooted, and no trading program was running at all. Later I reinstalled the whole window xp system and everything has been fine since then, I thought maybe it was a virus or something irregular happened. I am not sure such thing will not happen in the future. So my question is: is there a way/software that can monitor the running of my AT system, giving out a (sound ) alert whenever something wrong is going on, or when the AT system is halted /exited irregularly ?
