I am using windows 7 64 bit and deleted the shortcut to internet explorer. I have tried deleting internet explorer through programs files and deleting it as administrator as well however I am unable to delete it. A pop-up comes up that reads "you require permission from TrustedInstaller to make changes to this folder". I use firefox and Internet Explorer randomly opens itself and then laggs. This is such an annoying issue. Opinions might differ about which browser is better but I am not going to use IE and would like this issue to stop. Any help is appricated.
