Hi,
Sounds bad. Let's try this. Delete the Combofix from your desktop and download a fresh copy, but we'll do it a little differently this time:
Download
Combofix from any of the links below. You
must rename it before saving it. Save it to your desktop.
Link 1
Link 2
Link 3

--------------------------------------------------------------------
Double click on
Combo-Fix.exe & follow the prompts.
- When finished, it will produce a report for you.
- Please post the C:\ComboFix.txt along with a HijackThis log so we can continue cleaning the system.
Note:
Do not mouseclick combofix's window while it's running. That may cause it to stall
