Microsoft Anti-Spy auto exits.

[Guest]

It works well until today. I'm not sure why but it doesn't open at start up.
And when I open it manually, it auto-exits. When I try to uninstall it
through "Add and Remove Program", it auto exits before it is fully uninstall.
So, I deleted Anti-Spy through the Program Files folder. Then I try to
install it again but the installer auto-exits. I try redownloading another
installer from Microsoft's site but the installer auto-exits too.

I wonder what is the cause?

Thanks in advance.
