Chances are you also have stuff running that you dont need.
I saw processes named 'helper' in a task list... IMO those are suspect. probably not adware or a virus, but something you can get rid of.
Put your mouse cursor over each icon in your system tray. if its something you use a lot - keep it. if not - get rid of it. either by uninstalling the program, or disabling the icon.
example:
I saw an nvidia icon in your system tray. that runs as a process. If you use the features on that menu, then keep it. if you dont.. disable it.
My laptop boots up and shows 17 processes running under windows 2000, so its possible to drasticly reduce the number of processes.
