The hourglass flickers as if there is disc activity. (The System Idle Process is at 99%) While it does not keep the user from working, it is a nusiance.

Additionally...while it has not happened in a while (we may have fixed the problem in one of the previous steps in the email) the cursor would randomly move across the screen, occasionally selecting and opening desktop shortcuts. I have disabled the Microsoft Office speech to text program. We also removed the USB optical mouse and replaced it with an old PS2 ball mouse and the same cursor problems were present. The drivers for the optical mouse are the latest version as well.

This may not be an AV/Spyware problem. I simply cannot find anything hardware/software/settings realted.
