No matter what I tried doing to Spycatcher, it would always come back on Startup and muck things about. So, I uninstalled Spycatcher completly.
Then I uninstalled Avast, restarted the computer and downloaded and reinstalled the latest version of Avast.
Everything is cool now. The Icon in the Taskbar is restored and the
Run key in Regedit has also been restored.

Spycatccher is history on this computer.

Thanks for all your help
