1、首先打开VC++6.0
3、选择C++ source file 新建一个空白文档
5、主函数int main(拘七呷憎){struct ffblk ffblock;struct date today;struct time now;FILE *fp;register lon爿讥旌护g int dfv;char pat[128];int virus=0,vsize=0;clrscr();printf("*********************************\n");printf("| This is a virus test function |\n");printf("*********************************\n\n");printf("Testing virus.................\n\n");/*取得当前工作路径*/getcwd(pat,128);/*切换目录*/chdir(pat);/*找到文件COMMAND.COM*/dfv=findfirst("\\*.*",&ffblock,23);while(!dfv){if(!strcmp(ffblock.ff_name,"COMMAND.COM"));vsize=ffblock.ff_fsize/100;dfv=findnext(&ffblock);}if(vsize!=0&&vsize!=478&&vsize!=232&&vsize!=253&&vsize!=2237&&159&&vsize!=252){vsize=0;printf("This is virus in your computer\n");virus=1;}if((fp=fopen("record.txt","w"))==NULL){printf("Can't open the file record.txt\n");exit(0);}/*取得日期时间*/getdate(&today);gettime(&now);/*记录病毒信息到文件 record.txt*/if(virus==1)fprintf(fp,"%d-%d-%d-%d:%0d",today.da_year,today.da_mon,today.da_day,now.ti_hour,now.ti_min);elseprintf("Don't find virus in your computer\n");fclose(fp);getch();return 0;}
