Hello,
Your problem is actually related to a bug with Spy Sweeper's new method for updating the definitions -- the items being detected by the program aren't actually present on your computer.
This problem has a pretty easy fix. All you need to do is open Spy Sweeper, click the Home button, then hold down the Ctrl and Alt keys on your keyboard while double-clicking the Spy Sweeper icon. Doing so will bring up a small menu of additional support buttons. One of these buttons is labeled Download Full definitions. Click this button and let the definitions fully download. After doing this, you should be able to successfully sweep your system again.
