PHP.Pirus是第一只被发现的用PHP写的病毒,它寻找扩展名为.php和.htm的文件，并插入代码去调用自己。这个病毒只能在以php为解释器的服务器上。访问一个被它感染的网页并不能感染上病毒。

种类:病毒
感染长度：718字节
病毒发现时间：2000-11-13
危害程度: 疯狂程度:低;
破坏程度：低;
传播：低
疯狂程度:
    被感染的计算机:0-49
    被感染的站点:0-2
    地理分布: 低
防范:容易
消除:容易

技术描述:
    这个病毒是用php写的，长度为718字节
    当发作时，它寻找当前目录中以.php和.htm结尾的文件，如果发现有可写文件，它先判断文件是否已感染，如果没被感染，它会在文件中插入一行,优先执行病毒文件
消除:
    病毒文件名可能是变化的，所以完全消除它，必须:
    1. 删除原始病毒文件
    2. 去掉所有已感染的php和htm文件中的病毒代码
    如病毒文件名假设为virus.php,那么所有感染文件中的如下语句必须删除 include "virus.php"
/php>
