I have installed the windows 7 Home Premium 64 bit on mine system and I have also installed the McAfee Security Center. I am using the internet explorer since 3 months and I donít have any issue on this. But in private browsing do not respond while unlocking the files. As well when I write the address in the address bar and after that when I click the go button, It was not working. I have tried lots of threads to solve this issue but I didnít have the any issue on that. Can anyone suggest on this and so that I can solve mine issue. Please help out from.
