Hi,
WARNINGUnfortunately one or more of the infections I have identified are Backdoor Trojans, IRCBots or other Malware capable of stealing very important information. You need to stop using all Internet Banking sites, change passwords to all sites with sensitive information from a clean computer and phone your bank to inform them that you may be a victim of identify theft. More often than not, we advise users that a full reinstallation of their Operating System is the only way to ensure that their computer will ever be 100% clean again.
Unfortunately I have found what is known as the ZeroAccess rootkit on your system. It is an especially nasty infection that can take quite some time to clean as well as may have damaged your system files itself. As a warning, during the cleaning (if you choose to do so) you may lose internet access with this computer and in the end we may need to reinstall the operating system anyway depending on the extent of the infection.
If you would like to format and reinstall your Operating System please let me know and we can assist you with that.
If you would like to continue with the cleaning, please continue with the following instructions and I will be more than happy to help. 
Please download and run ERUNT (Emergency Recovery Utility NT). This program allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed. **Remember if you are using Windows Vista as your operating system right-click the executable and Run as Administrator.
If you are running Malwarebytes 1.6 or better, please disable it for the duration of this run.
To disable Malwarebytes

[*]Remove the tick from “Start Protection Module with Windows” as seen below
