Romantic gesture
Good night, sweet prince, and flights of angels sing thee to thy rest

像邮件主题一样,其内容也是随机选取的,从下面的列表中:
Happy Valentines
I hope you like the card I‘ve attached,
even if you don‘t feel the same.
[Sender‘s Name]

Febuary Feelings
It‘s that time of year again.
But I‘m still only sedning a card to you.
[Sender‘s Name]

Hi
I feel like a child sending you this card
but I just had to do it.
[Sender‘s Name]

...and every breath I ever took,
every tear I ever wept,
Every star I wished upon,
Seemed nothing until now.
[Sender‘s Name]

In this life we cannot do great things.
We can only do small things with great love.
[Sender‘s Name]

发送者的名字从注册表中下面这个键中取得
HKLM\Software\Microsoft\Windows\CurrentVersion\RegisteredOwner

并且都会带一个名叫"ValentineCard.exe"的附件。如果运行了这个附件,病毒会将自身拷贝到系统目录,而且会在注册表启动项中,加入下面键值:HKLM\Software\Microsoft\Windows\CurrentVersion\Run\14th="%system directory%\ValentineCard.exe",也会加入下面这个键值:HKLM\Software\Microsoft\Windows\CurrentVersion\Valentine="true"。

这个病毒包括一个音频文件与一个JPEG格式的图片。如果该病毒在星期四触发的话,它会产生一个图片文件"c:\evil.jpg",
并且会执行这个"start c:\evil.jpg".这样将会用缺省的看图软件来打开这个JPG图片文件。

因为BUG原因,实际上是由一个音频文件替换了"c:\evil.jpg",而且这个音频文件也不会正确执行。而图片文件"c:\evil.jpg",将会永远不能被该病毒创建或者显示!

在有些情况下,该蠕虫病毒也能正确创建音频文件"c:\1.wav",如果有声卡的话,会立即执行。这个音频文件是由一个女人说的一句话"somebody loves you",你可以点击这里下载!
