xcrash.err这是什么？求详解

中了文件夹病毒后桌面就出现了这个,下了个专杀好了

服务器端（接收端）程序：1、创建套接字（socket）。2、将套接字绑定到一个本地地址和端口上（bind）。3、等待接收数据（recvfrom）。4、关闭套接字。客户端（发送端）程序：1、创建套接字（socket）。2、向服务器发送数据（sendto）。3、关闭套接字。client.c#include <Winsock2.h>#include <stdio.h>void main() if ( LOBYTE( wsaData.wVersion ) != 1 || HIBYTE( wsaData.wVersion ) != 1 ) SOCKET sockClient=socket(AF_INET,SOCK_DGRAM,0); SOCKADDR_IN addrSrv; addrSrv.sin_addr.S_un.S_addr=inet_addr("222.26.28.227"); addrSrv.sin_family=AF_INET; addrSrv.sin_port=htons(5001); sendto(sockClient,"Hello",strlen("Hello")+1,0, (SOCKADDR*)&addrSrv,sizeof(SOCKADDR));// printf("%d\n", sendto(sockClient,"Hello",strlen("Hello")+1,0,// (SOCKADDR*)&addrSrv,sizeof(SOCKADDR))); closesocket(sockClient); WSACleanup();}server.c#include <Winsock2.h>#include <stdio.h>void main() if ( LOBYTE( wsaData.wVersion ) != 1 || HIBYTE( wsaData.wVersion ) != 1 ) SOCKET sockSrv=socket(AF_INET,SOCK_DGRAM,0); SOCKADDR_IN addrSrv; addrSrv.sin_addr.S_un.S_addr=htonl(INADDR_ANY); addrSrv.sin_family=AF_INET; addrSrv.sin_port=htons(5001); bind(sockSrv,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR)); SOCKADDR_IN addrClient; int len = sizeof(SOCKADDR);// int len=sizeof(addrClient); char recvBuf[100] = "\0"; printf("Wating for message from others: \n"); int a = recvfrom(sockSrv,recvBuf,100,0, (SOCKADDR*)&addrClient,&len); if(a == SOCKET_ERROR) printf("%s\n",recvBuf); closesocket(sockSrv); WSACleanup();}
