Chinese Crossfire problem...

Well I decided to run a uninstall for chinese crossfire and it happened to start removing every file on my pc.
I got it from the QQ site
the file name is "´©Ô½»ðÏßжÔØ.exe"

Why did it do this?
I ran the file two times since then and no problems...
But it did remove about 5k files before I got to closing it.
Why did it do this? Does anyone have any help or solution for me? I ran a system restore and have gotten my files back, but why did this happen?

An update maybe gone wrong? Why don't you uninstall it from program files?
