|I myself faced the same issue & tried all possible methods found in the net to remove the icon but was not successful, at last I found out the procedure of getting rid of the Shredder icon from my desktop.|
Its a very simple and fast procedure. First click the start button on the extreme bottom left side of the screen then on the Run/start box type "regedit". A new window with regedit data will appear, press Ctrl F and type "Shredder" or "PC Confidential" in the search box, press enter. On the right side pane you can find the file containing the Shredder icon or PC Confidential. Now delete it & restart your machine.
