Ok, it is listed in the Start Up section of your HJT log here;
O4 - HKUS\S-1-5-18\..\Run: [MySpaceIM] C:\Program Files\MySpace\IM\MySpaceIM.exe (User 'SYSTEM')

You can run HiJackThis again and put a check mark in that entry and then click Fix Checked.
Exit HJT.
If you NEVER use this you can uninstall the program. Not familar with the MySpace IM but it may be listed in Add/Remove and you can remove it entirely from there.
If it isn't listed there it is in the folder C:\Program Files\MySpace\
so it has been downloaded to the computer at some time. Now I use MySpace occasionally but have never used the IM program and just checked my computer and I do not have a MySpace folder in Program Files so I am guessing that you must have other MySpace items installed. As I said, I use My Space occasionally and have never had problems going through the various items on the page without anything installed from MySpace so that is what you should check out.
