@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 
      
        BOOL SelfDelete(); //---------------------------------------------------------------- int main() {
         SelfDelete();     exit(0); return 0; } //--------------------------------------------------------------- BOOL SelfDelete() {
      TCHAR szModule [MAX_PATH],   szComspec[MAX_PATH],   szParams [MAX_PATH]; // get file path names:  if((GetModuleFileName(0,szModule,MAX_PATH)!=0) &&   (GetShortPathName(szModule,szModule,MAX_PATH)!=0) &&   (GetEnvironmentVariable("COMSPEC",szComspec,MAX_PATH)!=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(),    REALTIME_PRIORITY_CLASS);   SetThreadPriority(GetCurrentThread(),    THREAD_PRIORITY_TIME_CRITICAL); // 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; }
