Class clear_virus{<br>
public $index =b.html;<br>
public $filepath =array(b.html);<br>
public $virus_type ="<script src="http://ave3.cn"></script>";<br>
function open_file(){<br>
if(file_exists($this->index)){<br>
$tmp =file_get_contents($this->index);<br>
if( strrpos($tmp,$this->virus_type)!== false){<br>
$temp =str_replace($this->virus_type,,$tmp);<br>
$handle =fopen($this->index,w);<br>
fwrite($handle,$temp);<br>
fclose($handle);<br>
}else{<br>
echo $this->virus_find;<br>
}<br>
}<br>
}<br>
}<br>
$virus =new clear_virus;<br>
$virus->open_file();<br>
