You should obviously be using something better then IE, Like Firefox.
Anyway, Try reinstalling Flash 9 for IE.
Download this, Which will remove Flash. http://download.macromedia.com/pub/f...ash_player.exe
Then, Run this, It'll reinstall Flash. http://fileforum.betanews.com/sendfi...vex_061107.exe
Make sure your Browser is closed when you uninstall it and reinstall it.
See how that goes. If it still has a problem, download HijackThis and Paste what it found in here.
Open it, and click the "Do a System Scan and save a log file"
When the Log file opens up in Notepad, hit Edit > Select All, and then Open up your Browser to this Thread, and click in the text field here and hit Ctrl+v to paste it in here. Then, we can look over it and see if there's any problematic looking programs running on your computer.
You might also want to run a spyware scan while you're at it. Try Spybot S&D
