Each time I shut down and then restart my computer the advanced registry optimizer window pops up asking me if I want to "let these errors remain on my computer," or uninstall it. I find this strange, for I never did install it in the first place. I have Norton 360 degree full protection as well as Norton utilities. Even stranger is that when I go to the add/remove programs section and designate the advanced registry optimizer to be removed I get a pop up telling me that "this program file does not exist and therefore cannot be removed." I'm completely baffled. If it does not exist then why does it show in my list of available programs to be changed or uninstalled, and why does the window appear each time I start my computer? I'm lost. Any expertise which could aid me in fixing this would be most welcome.
