Hello, Welcome to BleepingComputer.
I'm nasdaq and will be helping you.
 
If you can please print this topic it will make it easier for you to follow the instructions and complete all of the necessary steps.
===
Please download ComboFix from one of these locations:
IMPORTANT !!! Save ComboFix.exe to your Desktop
  • Disable your Anti-Virus and Anti-Spyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools.

  • Double click on ComboFix.exe & follow the prompts.

  • 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.  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.

  • 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.

  • Some Rookit infection may damage your boot sector. The Windows Recovery Console may be needed to restore it. Do not bypass this installation. You may regret it.

**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 shall produce a log for you.  Please include the C:\ComboFix.txt in your next reply.
 
Note: If you have difficulty properly disabling your protection programs, refer to this link --> http://www.bleepingcomputer.com/forums/topic114351.html
 
Do not mouse click ComboFix's window while it's running. That may cause it to stall
 
Note: If after running ComboFix you get this error message "Illegal operation attempted on a registry key that has been marked for deletion." when attempting to run a program all you need to do is restart the computer to reset the registry.

Third party programs if not up to date can be the cause of infiltration an infection.
 
Please run this security check for my review.
 
Download Security Check by screen317 from here.
  • Save it to your Desktop.

  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.

  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.

===
 
Search and delete the AdWare, PUP (Potentially Unwanted Program) installed on your computer.
 
Please download AdwCleaner by Xplode onto your Desktop.

  • Close all open programs and internet browsers.

  • Double click on AdwCleaner.exe to run the tool.

  • Click on Delete tab follow the prompts.

  • A log file will automatically open after the scan has finished.

  • Please post the content of that log file with your next answer.

  • You can find the log file at C:\AdwCleaner[Rn].txt (n is a number).

 
Please post the logs and let me know what problem persists.

Secure your system by updating 3rd party programs.
 
Your version of Java is outdated and needs to be updated to take advantage of fixes that have eliminated security vulnerabilities.
 
Be careful not to install malware posing as Java update!
Important read this blog.
 
Quoted from the page.
"In light of the recent events surrounding Java, users must seriously consider their use of Java. Do they really need it? If yes, make sure that users follow the steps we recommended and get the security update directly from the official oracle website." at:
 
How to disable Java in your browsers
 
You can manually check your present version and update as recommended.
 
If present remove the old version(s) of Java using the Add/Remove Programs applet.
 
 Java™ 6 Update 39
 
Java 7 update 10 introduced important new security controls
You can read about it here.
 
Note
Java security update installs Ask Toolbar by default -- a single click in a multi-step installer.
I suggest that your un-check the box "Install the Ask Toolbar" before proceeding.
===
 
Critical vulnerabilities have been identified in old version of Adobe Flash Player please get the latest version.
 
Adobe has released security updates for Adobe Flash Player 11.6.602.168 and earlier versions for Windows, Adobe Flash Player 11.6.602.167 and earlier versions for Macintosh, and Adobe Flash Player 11.2.202.270 and earlier versions for Linux. 
 
 
On the top of the page you will be given an opportunity to download the version for your operating system.
Make sure you select appropriate version.
 
You will also have an option to install the Free! McAfee Security Scan Plus Un-check the box if you are NOT using McAfee's virus protection software.
 
For the users of Internet Explorer download version 11.
===
 
Get the latest version of the Adobe Reader.
Before your download I suggest you unckeck the box on the top right "Yes, install McAfee Security Scan Plus - optional" this is not required if you are not a McAfee subscriber. While the installation is in progress you can also deny the installation of any other programs that may be suggested.
 
When installed remove your old version of the Reader using the Add/Remove Programs applet if present.
===
 
Please let me know of any remaning issues with this computer.
