WUAUCLT spyware/virus

I have the wuauclt.exe spyware/virus on my wife's laptop after she let our nephew use it and download who knows what. I am sure this topic has come up on one of the GeekPolice forums, but I cannot find it. As a newbie, I am sure I just haven't looked in the right place. Could someone point me in the right direction? Thank you in advance.

Never mind. I found it. Sorry to bother you.

depending on where you stored it, it will be in one of two places. Program files is more for user and 32 bit programs, while Program Files (x86) is more for system and 64 bit programs.
if you installed it, look in the program files first
anyone out there, please correct me if I am wrong.
