Internet Explorer Hacker Problem

Question

I switched to Mozilla Firefox when news of hackers getting passwords on IE came out a few weeks ago. I don't like Firefox and want to switch back to IE. At the time of the news it was said that there was a process to safe guard your info but, it was complicated and not a sure thing. I don't want to try that. I want to know if the problem has been solved and is it safe to return to IE?
