Could anyone help me? I have windows 7 with norton antivirus. I loaded adobe reader x. Everytime I have tried to open a pdf file in Internet Explorer, I receive amessage that my security settings won't allow me to do so. I have tried reducing my security settings in IE nad have disabled my antivirus program but the problelm persists. I have removed Reader X and installed version 9 but the problem persists. Any ideas?
