i have been trying to fix my sisters computer using msconfig and stuff like that. there is no doubt in my mind that there is viruses on it but that is not the problem right now. the problem is i tried to download internet explorer 7 and it said "you do not have administrative privileges to do this". now i know wut ur thinkin, im not logged on as administrator, but i am. ive checked a million times. the computer will not let me change any settings. it is like i am logged in as a guest but i am not. this computer is usually used at a college for the net but now its on a wireless router. however i dissconnected from the wireless network completely and it still will not let me change any settings. wuts wrong with it?
