Hi, After having installed SnoopFree (Anti KeyLoger) I got the following messages: a) "SnoopFreeUI.exe (UserInterface) is blocked from creating a Global Debug Hook". (After that I allowed it to create Hooks.) Questions: 1) what is a debug hook? 2) Did I the rigth thing? 3) If not how to undo it? b) "SnoopFreeSVC.exe (Main program) is trying to modify a service called SnoopFreeSVC.exe"; so it is try to modify itself . This message is repeated time and again but I have not done anything as I do not know what is going on. Any help? Ems.
