自2003起，QQ尾巴病毒可以算是风光了一阵子。它利用IE的邮件头漏洞在QQ上疯狂传播。中毒者在给别人发信息时，病毒会自动在信息文本的后边添上一句话，话的内容多种多样，总之就是希望信息的接收者点击这句话中的URL，成为下一个中毒者。

　　下面我将要讨论的，就是QQ尾巴病毒使用的这一技术。由于病毒的源代码无法获得，所以以下的代码全是我主观臆断所得，所幸的是效果基本与病毒本身一致。

-Since 2003 onwards, QQ tail virus can be regarded as scenery for a while. It uses IE' s vulnerability in the QQ on the message header madness spread. Poisoning in the information issued to others, the virus will be automatically added behind the text in the Information sentence, then the contents of a wide variety, in short, it is hoped the information the recipient click on the phrase in the URL, to be the next one poisoned. Now I will be discussing is QQ tail virus used in the technology. Because the virus' s source code is not available, so the following code all I received a subjective assumption, but fortunately the effect of the basic agreement with the virus itself.
