Isn’t it kind of strange that Mircosoft has to buy a company to be able to release a tool to remove spyware from their own operating system? Shouldn’t they have enough expertise on Windows among their employees? They wrote the system after all. Therefore they should know, where and what the hooks and places are, that spyware uses to ensure that it is executed on every startup. And also they should understand the mechanisms which are employed by malicious code to hide itself...

This leaves me puzzled.
