Keep a copy of Malwarebytes removal tool on your desktop.
It's free.
Just run a full system scan and this will catch it (and any other malicious software.)

I use Malwarebytes as well as SUPERAntiSpyware.
What one misses, the other one gets. My compurts are free of any rubbish that tracks or hogs your PC.
