I cant seem to open up any shortcuts on my desktop or even some executables on cd's or in program files. Windows keeps telling me that the files are not found but when i look in the directories they are there. problem started after removal of nortons anti virus. had a problem with install so i uninstalled it and i got rid of files it said were in quarintine. so maybe some needed windows files were in there and are now gone? any help would be greatly accepted. I have already tried re-installing OS over itself but no luck and i dont know the adminastrator password since I got this as a good working used computer.
