WsaErr = WSAStartup(MAKEWORD(2, 2), &wsaData) Here is a shortened and smaller version of the program above: #ifndef UNICODE What do I have to change to make my program not longer detected by AntiVir? If I delete the accept()-function in 'winMsgServerAcceptThread', the program can be executed and no virus is detected. SendMessage(hwnd, WINMSG_WM_CLIENT_ACCEPTED, NULL, NULL) Swprintf(statusBuffer, 10000, L'%s Connection with %s:%d established!', statusBuffer, serverIPString, WINMSG_STD_PORT) ĭWORD WINAPI winMsgServerAcceptThread(LPVOID lpParam) Swprintf(statusBuffer, 10000, L'%s listen() successful! Wait for client.', statusBuffer) ĬreateThread(NULL, NULL, winMsgServerAcceptThread, 0, 0, &winMsgServerAcceptThreadID) Swprintf(statusBuffer, 10000, L'%s Error: listen() returned code 0x%x!', statusBuffer, WSAGetLastError()) Swprintf(statusBuffer, 10000, L'%s Error: bind() returned code 0x%x!', statusBuffer, WSAGetLastError())

If(bind(mSocket, (SOCKADDR*)&socketService, sizeof(socketService)) = SOCKET_ERROR) //No, I am server SocketService.sin_addr.s_addr = inet_addr(ownIP)

If(connect(mSocket, (SOCKADDR*)&socketService, sizeof(socketService)) = SOCKET_ERROR) //Am I client? SocketService.sin_port = htons(WINMSG_STD_PORT) SocketService.sin_addr.s_addr = inet_addr(WINMSG_RECV_IP) Swprintf(statusBuffer, 10000, L'%s Establish connection.', statusBuffer) Swprintf(statusBuffer, 10000, L'%s Socket with IP %s successfully initialized!', statusBuffer, ownIPWC)

Strcpy(ownIP, inet_ntoa(*(struct in_addr*)*thisHost->h_addr_list)) Swprintf(statusBuffer, 10000, L'%s Error: socket() returned code 0x%x!', statusBuffer, WSAGetLastError()) MSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP) Swprintf(statusBuffer, 10000, L'%s Error: System doesn't support WinSock version 2.2!', statusBuffer) If(LOBYTE(wsaData.wVersion) != 2 || HIBYTE(wsaData.wVersion) != 2) SendMessage(hwnd, WINMSG_WM_UPDATE_STATUS, 0, 0) Swprintf(statusBuffer, 10000, L'%s Error: WSAStartup() returned code 0x%x!', statusBuffer, WSAGetLastError()) Int wsaErr = WSAStartup(MAKEWORD(2, 2), &wsaData) LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) ĭWORD WINAPI winMsgServerAcceptThread(LPVOID) But when I call the accept() function and compile the program, AntiVir tells me that it found a virus ('BDS/Backdoor.Gen') im my application. I made a Windows program with WinAPI and WinSock 2.2.
