I have the Automatic Updates turned on and I just assumed that the computer was doing everything itself.
Also, in terms of the original problem, which was that the computer was not shutting down properly, I recently noted that one of the programs I use to listen to music, a Cowan program called jetAudio, was acting weirdly. When I turned on the music, usually the program itself would appear minimized at the bottom of the page so I could shut off the music when I wanted. But recently this stopped happening--the program never minimized but the music kept playing!
So I thought that maybe the reason I couldn't shut down was because this program maybe kept on and on, even though it didn't show up in my "task manager" which made me feel even more suspicious toward it. Also, I kept looking around and somewhere in the microsoft site I think it was I saw a note that said to disable screen savers.
Anyway, I both deleted this jet audio program (wait till my son finds out!) and turned off the screen saver (a Microsoft one), and now I don't have trouble shutting down.
I do want to thank you for looking at these logs. If you say there is no malware, then my heart is totally at ease!
Thanks and have a great weekend.
