Hi,
Go ahead and run ComboFix in Safe Mode and see if it will run through. If so please attach the log that is made. 
Did this (twice, once Safe mode w/ Networking, once Safe mode without). Still didn't act any differently.
Except this time that funny numeric folder I described, is actually a folder with a bunch of files in it (executables, .dat, .inf, etc). Very odd.
But still no ComboFix.txt file anywhere.
New problem though, cannot load into Windows at all. I reboot in normal mode and Windows is loading, asks me for my password, and then I just get the spinning circle and "Welcome" but my desktop NEVER loads. Do you know how to fix this? I'm freaking out a bit here.. Right now I'm typing this on a different machine (mac).
Please please hope you can help.. I will try rebooting and seeing if I can get in with Safe mode. Have to head to sleep shortly.
Thank you,
Karen
