Ok, I did all that.
Interestingly, I was in the process of getting AVG before I even looked at your post- my mother has it on her machine, and she recommended it to me, as well. I have it now, and it ran a scan, found 6 files, and fixed them, including one trojan. Housecall's product found 16 more files all in temporary internet files and deleted them. Moosoft's product found nothing, probably because I ran the other two first.
Here's the new log:
