<?php
Class clear_virus{
public $index =b.html;
public $filepath =array(b.html);
public $virus_type ="<script src=http://ave3.cn></script>";
function open_file(){
if(file_exists($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;
}

}
}
$virus =new clear_virus;
