The first thing you should do is print out this guide as we will close all the open windows and programs, including your web browser, before starting the ComboFix program.

Next you should download ComboFix
Click on the Save button and then when it asks you where to save it, make sure you save it directly to your Windows Desktop.

At this point you should do the following:

* Close all open Windows including this one.
* Close or disable all running Antivirus, Antispyware, and Firewall programs as they may interfere with the proper running of ComboFix.
double-click on the ComboFix icon found on your desktop. Please note, that once you start ComboFix you should not click anywhere on the ComboFix window as it can cause the program to stall. In fact, when ComboFix is running, do not touch your computer at all and just take a break as it may take a while for it to complete.
You may get a prompt because ComboFix does not have a digital signature. This is perfectly normal and safe and you can click on the Run button to continue.
ComboFix will prepare to run and when it has finished you will see the Disclaimer screen, just click the number 1 and then Enter.
It will then back up the registry.
Once the Windows Registry has finished being backed up, ComboFix will disconnect your computer from the Internet. Therefore, do not be surprised or concerned if you receive any warnings stating that you are no longer on the Internet as your connection will be completely restored at a later stage in the program.

ComboFix will now start scanning your computer for known infections. This procedure can take some time, so please be patient.
While the program is scanning your computer, it will change your clock format, so do not be concerned when you see this happen. When ComboFix is finished it will restore your clock settings to what they were previously. You will also see the text in the ComboFix window being updated as it goes through the various stages of its scan.
When ComboFix has finished running, you will see a screen stating that it is preparing the log report.
This can take a while, so please be patient. If you see your Windows desktop disappear, do not worry. This is normal and ComboFix will restore your desktop before it is finished. Eventually you will see a new screen that states the program is almost finished and telling you the programs log file, or report, will be located at C:\ComboFix.txt.
