Hi there and welcome
To do this, Run Safari browser and Click Reset Safari.
Check the all boxes and Click Reset.
This will then remove it for you. If you needed it removed from other browsers as well, let me know.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
