You should begin with all the steps on this sticky
Once you have completed all the above steps then post back here with all the requested logs.

Just going through your HJT log again, which is the old version by the way, you should remove that one and go with the newest version which is HiJackThis version 2.0.2
Your Java is also out of date, you are running update 6 version 4, current version is 6 update 7.
You said you were using MSN Messenger when you shut down but now it won't run. Your HJT log shows 5 instances of it running in the background, it is also in auto starts.
Try going to the Taskmanager and shutting down all those that are running in the background and see then if you can open it up.
