Ok yes that was ok putting it in this thread. I'm not a hijackthis guru but one obvious entry needs fixing. Open Hijackthis and scan again. Put a check in this one and tell it to fix it:

O2 - BHO: (no name) - {09F0F280-FB9A-481B-B69A-CB00DC44D027} - (no file)

I see nothing else untoward or bad in your log, but I believe the above might be why you're getting the IE close problems.
