I am having this problem also. I updated my Internet Security to the latest version and since then it will not automatically load. I have a win7 64bit as well. i tried repair and it said finished, then said that uninstall did not complete properly, which i just closed down as i did not want to uninstall completely (don't remember my activation code or where to find it). I then restarted computer and I get a message about one click program, don't know if it is about this problem or not.
