Hi Corrine,
I did have an old version of TrendMicro antivirus installed on my machine. I think it was a throw-in along with the computer when I bought it. It did have an expired license, and I uninstalled it, but I do still have McAfee antivirus on my machine. McAfee is still under license.
I also ran ComboFix again using the bolded text. Let me know if you would like me to post the log file.
