Ok. We can do some cleanup.

To uninstall ComboFix

• Click the Start button. Click Run. For Vista: type in Run in the Start search, and click on Run in the results pane.
  
• In the field, type in ComboFix /uninstall
  

(Note: Make sure there's a space between the word ComboFix and the forward-slash.)

• Then, press Enter, or click OK.
  
• This will uninstall ComboFix, delete its folders and files, hides System files and folders, and resets System Restore.

Clean out your temporary internet files and temp files.

Download TFC by OldTimer to your desktop.

Double-click TFC.exe to run it.

Note: If you are running on Vista, right-click on the file and choose Run As Administrator

TFC will close all programs when run, so make sure you have saved all your work before you begin.

* Click the Start button to begin the cleaning process.
* Depending on how often you clean temp files, execution time should be anywhere from a few seconds to a minute or two.
* Please let TFC run uninterrupted until it is finished.

Once TFC is finished it should restart your computer. If it does not, please manually restart the computer yourself to ensure a complete cleaning.

I uninstaled combofix and then ran TFC. I then restarted my computer, but a problem occurred. After the restart my sound wouldn't work. My speakers worked fine but the volume icon was gone from my taskbar and anything I played on youtube no sound would come out. I did a system restore to the day before which fixed the problem. Also i'm still having the issue with windows not automatically logging me in.
