  You will see the following image:
  

Click I Agree to start the program.

ComboFix will then extract the necessary files and you will see this:



As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. This will not occur in Windows Vista and 7

It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.

If you did not have it installed, you will see the prompt below. Choose YES.



Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:



Click on Yes, to continue scanning for malware.

When finished, it will produce a report for you. Please post the contents of the log (C:\ComboFix.txt).

Leave your computer alone while ComboFix is running. ComboFix will restart your computer if malware is found; allow it to do so.

Note: Please Do NOT mouseclick combofix's window while its running because it may cause it to stall.

Windows Defender is MS's Anti-virus and anti-spyware program and it comes with Windows 8. If you're going to use another AV all you need to do is de-activate it. Here are the directions to do that. Keep in mind that I have my Windows 8 configured with at Start button. Click Start, Programs, Windows Systems, Windows Defender. Open it and click on Realtime protection and make sure it's off.
We can now do some cleanup.

Download this program and run it Uninstall ComboFix .It will remove ComboFix for you.

Click Start> Computer> right click the C Drive and choose Properties> enter
Click Disk Cleanup from there.



Click OK on the Disk Cleanup Screen.
Click Yes on the Confirmation screen.



This runs the Disk Cleanup utility along with other selections if you have chosen any. (if you had a lot System Restore points, you will see a significant change in the free space in C drive)
