For what it's worth, I'm not longer seeing the "Ending program - n" message when I shutdown, but I'm still worried. Below I've pasted both the HijackThis log and then, after it, the malwarebytes log. eset and spybot came up clean and malware bytes found a suspicous.

In any case, I ran esetnod32, malwarebytes, and spybot s&d. After googling, I found nothing definitive on this answer, though it's listed as a trojan on process library: I noticed when I shut down today a popup that said "Ending Program - n," and that seemed like a red flag for an infection of some sort.
