As TheChair suggests, the most likely cause of 'not responding' problems with browsers is a fault with the updating function of your antivirus software.
If you have to use AVG, I suggest uninstalling it completely, restarting your computer and then reinstalling it. (You might need to use AVG Remover to effectively uninstall AVG:

I used to love AVG but I chose to ditch it precisely because of the type of problems which you're currently experiencing. (Microsoft's own products are at least as bad). I now use Avast instead, without any problems.
IE is, and always has been, a total joke. Get yourself a decent browser! (My own choice is Firefox. Avant is just as good and, if you don't mind Google trying to take over everything you do, Chrome is worth considering).
