Internet explorer problems

Yeah um so every time I use internet explorer its fine but the problem is when I try to close it, it wont close for some odd reason...
Sooo can anyone help me fix the problem and oh I have vista and oh yeah my computer is kinda not runnin fast as it use...

to how do I make run fast or faster please help???

well I'm not sure about how to make it run faster there is this thing you can buy that can do it. I would go to bestbuy and talk to geek squad about that. Your page wont close because the internet is using too much mb because you know its too slow so it needs more mb to run. If you cant get out the do the ctrl, alt delete thing and then go to processes and find iexplore in there and it will exit out.

In my opinion, Internet Explorer sucks. Download Mozilla Firefox, and you should immediately see some improvement in speed. Also, another thing to try is a 'cleaner'. Go here to download a good one :http://www.ccleaner.com/ The cleaner will erase all the useless stuff your computer has on it and make it faster, too. If your computer just doesn't have a very good processor or memory capability, it's never going to be lightning fast, but this should help.
