I have successfully used Spybot Search and Destroy to remove spyware.
You won't get any demands to buy it. It works the way it is. In some cases I had to run it a couple times, depending on the level of infestation.
Also, in some cases after I downloaded it I had to unplug the internet/network connection from the back of the computer to run it successfully, depending again on how persistent the spyware was.
You will also be able to update the signature file. Do that before you run it.
Go here to get it, and then install and run it.
Keep me posted.

And finally, to get some systems clean I had to get Microsoft's spybot cleaner. Each seems to catch something the other misses.
Get Windows Defender latest release here.
