==Payload==
==Payload==
When the user runs the malware by executing the [[.exe]] directly, a picture of an Asian woman in full screen is displayed along with the "introduce dialogue" Chinese text showing line by line in the upper-left corner of the screen. However, a ghost version of the woman in the image will appear briefly along with a scream sound effect, before immediately returning to the original image.  
When the user runs the malware by executing the [[.exe]] directly, a picture of Madoka Ozawa, a Japanese adult actress, in full screen is displayed along with the "introduce dialogue" Chinese text showing line by line in the upper-left corner of the screen. However, a ghost version of the woman in the image will appear briefly along with a scream sound effect, before immediately returning to the original image.  


Before showing the initial payload, the malware will copy itself to the Windows directory as <code>ozawa.exe</code> and try to append itself to <code>win.ini</code> in order to auto start with the operating system. Judging from the decompiled source code, this only works on [[wikipedia:Windows 98|Windows 98]] and [[wikipedia:Windows ME|Windows ME]]. On [[wikipedia:Windows_XP|Windows XP]] or higher, there is no ''Run'' section in <code>win.ini</code> and the malware will not work apart from the initial payload.
