Jack,
I had to finally uninstall Norton. It said it had an error and kept popping up trying to fix it, but it never could fix itself. I also uninstalled my Chrome browser just incase it was creating problems. Anyway after I did this I thought maybe now I can run the combofix, which I did. It ran up to the very last. It had the "Almost done...., Please wait...., ComboFix's log shall be located at c:\combofix.txt displayed when it hung up. I had to reboot the machine as it was froze. Once it rebooted though the log was there, so I am attaching it. I hope it sheds some insight into what is going on.
Thanks,
Serena
PS Computer is still freezing. About the only difference now is the mouse will move around (didn't before), but when you click on something it does nothing, so essentially it still does nothing.
