Heard about this a few years ago.
Here is something I found online from Lenovo.
Take a look:
There was an application some years ago where something like this was installed into Lenovo computers, there is an application that gets rid of it.
Scroll down to the list of machines listed and see if your model is listed there, it will also show you what exactly what it will be getting rid of. One of the items listed is something called LenovoCheck.exe.
