3 days ago, I updated America Online from version 9.0 to 9.0a. It slowed down my computer a lot...plus it just looked plain ugly

. So I uninstalled it and went back to 9.0. However, ever since that update, IE 6 has been messed up. If I open up 2 or more windows of IE at once, I won't be able to exit them with out using control + alt + delete, which is extremely annoying. I went through Add/Remove programs and found the following programs that I don't remember having on the list there before:
-Internet Optimizer
-Internet Explorer Q832894
-IE Win-enhancer
-Help Finder
-Help Features
-AOL Coach Version 1.0 (Build: 20040229.1 en)
-AOL Connectivity Services
-AOL
I removed Q832894 because a site said that you shouldn't apply this patch if you have IE6, only if you have IE6 s1 or something like that. I removed IE Win-enhancer as a test to see if it would get rid of the problem. I know it was stupid to remove it with out knowing what it is, but I'm extremely annoyed. I think that AOL Connectivity Services is just a program for my internet cable connection, but I'm not sure.
Also, whenever I open up IE, there is an add at the top of the page. The shortcut on it is
