程序通过创建线程实现删除自身（转）

@echo   off
loop
del  access.exe 
if   exist   access.exe
goto   loop
del   DelMe.bat

下面用C/C++语言表示创建DelMe.bat文件

FILE *pFile=NULL;
pFile=fopen("DelMe.bat","w");
if(pFile==NULL)
{
  return;
}
fputs("@echo   off\n",pFile);
fputs("loop\n",pFile);
fputs("del  access.exe\n",pFile);
fputs("if exist  access.exe\n",pFile);
fputs("goto  loop\n",pFile);
fputs("del  DelMe.bat\n",pFile);

再通过API函数执行DelMe.bat文件

下面通过创建线程实现程序删除自身

#include <windows.h>

int main()

    SelfDelete();
    exit(0);
    return 0;

 {
  // set command shell parameters
  lstrcpy(szParams," /c del ");
  lstrcat(szParams, szModule);
  lstrcat(szParams, " > nul");
  lstrcat(szComspec, szParams);
  
  
  // set struct members
  STARTUPINFO  si={0};
  PROCESS_INFORMATION pi={0};
  si.cb = sizeof(si);
  si.dwFlags = STARTF_USESHOWWINDOW;
  si.wShowWindow = SW_HIDE;
  
  // increase resource allocation to program
  SetPriorityClass(GetCurrentProcess(),

  // invoke command shell
  if(CreateProcess(0, szComspec, 0, 0, 0,CREATE_SUSPENDED|
   DETACHED_PROCESS, 0, 0, &si, &pi))
  {
   // suppress command shell process until program exits
   SetPriorityClass(pi.hProcess,IDLE_PRIORITY_CLASS);
   SetThreadPriority(pi.hThread,THREAD_PRIORITY_IDLE);
   
   // resume shell process with new low priority
   ResumeThread(pi.hThread);
   
   // everything seemed to work
   return TRUE;
  }
  else // if error, normalize allocation
  {
   SetPriorityClass(GetCurrentProcess(),
    NORMAL_PRIORITY_CLASS);
   SetThreadPriority(GetCurrentThread(),
    THREAD_PRIORITY_NORMAL);
  }
 }
 return FALSE;
}
