Hi LuZhao4
I am Dave, an Independent Advisor, I will help you with this . . .
Is that Debug file on your Desktop, and do you use the Chrome browser?
That file is known to be caused by Chrome, it is some sort of a bug, and Google support say the best way to stop the Chrome browser creating that file is to totally uninstall and re-install the Chrome browser, make sure to backup your favorites before you do that, just in case . . .
