Here is a link that i have used to try and identify unknown/unfamiliar background processes
http://www.answersthatwork.com/Taskl...s/tasklist.htm
Also it probably isn't a bad idea to run adaware or spybot to clear out any spyware that might be running on your system.
I can also tell you that some of the processes listed (devldr16, ahqtb, etc) are programs "needed" for some of your hardware to work (devldr16 = nvidia video card, and ahqtb = creative sound card), but usually a google search has helped me identify some of the "weird" process names.
