Looking at your HijackThis log, there appear to be many items that are starting up unnecessarily.]
If you go to Start --> Run --> Type msconfig and press Enter.
Go to the Startup tab and you can uncheck anythng you don't need on startup (like Java (jusched.exe), MSN, QuickTime (qttask.exe), ect...)
Don't worry, Unchecking these doesn't mean you disable them. Just run the program and those processes with start automatically.
