Seeing how no answered this...
You go to task manager and go to services.
Then you click the little button on the bottom right hand corner that says..."Services..."
You will see a list. Sort the list by clicking the name bar at the top of the list and it will go from Z-A.
xSherlock SHOULD be the first one.
Now right click it and go to properties.
There should be a drop down box that says "manual". Click it and select disable.
That should stop the service.
Thats all from memory so if I'm wrong...strike me down now...
