This spyware causes a specific problem. The mouse cursor is fine if you click on Desktop items, but once you move the cursor over to the task bar you get a hourglass, and you can't click on anything on the task bar including the Start button. Pressing the Windows key on the keyboard doesn't bring up the Start menu either. I've never seen this behavior before. Saw it for the first time couple of weeks ago. Wondering if it's a single spyware causing the problem or a combination of different ones.
