Get IM's Pwd use SYS

???????????????????? 今天下午沒有事做，把暑假回家寫的鍵盤過濾驅動改進成，密碼盜竊驅動。
???????????????????????????????????????????? 可以盜竊目前98%的網頁，程序，游戲的密碼。
?????????????????? 今天我來演示盜竊某著名IM軟件密碼，把密碼保存在C盤下zhuruinan.txt文本文件里
???????????????????????????????????? 通過加載zhusjm.sys過濾驅動，我們可以得到輸入的密碼。
???????????????????????????????????????????????? 通過DebugView查看我們的驅動輸出信息
