http://www.bleepingcomputer.com/combofix/how-to-use-combofixBefore running Combofix, temporary disable any firewall(s) shield(s) ect...to prevent any conflicts with Combofix. After Combofix is done scanning, it will create a log, for further instructions, save and paste the results by Attach File, or by Code Snippet so other experts can take a look at it. Once after the log looks clean, you may enable your firewall(s) shield(s) ect. Combofix will disconnect your machine from the Internet. Your Internet connection will be automatically restored just before Combofix completes its scan. If Combofix runs into problems, your Internet connection can be manually restored by restarting your machine.
You'll might need to rename the file before saving to your desktop so it will not be blocked.
Please note: Don't run Combofix in Safe Mode.
