Hello yoonekmason -
I see you ran the fix I posted previously - it seems to have gotten the bulk of the infection, but there is a lot to do still.

One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would advice you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the infection has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do. If you decide to go through with the cleanup, please proceed with the following steps.
Now if you choose to continue --

Step 1
Please download the following file(s) to your desktop
Once downloaded, please right click on each one and select Merge
Restart your computer after merging the file(s).

Step 2
Please download Farbar Service Scanner and run it on the computer with the issue.
  • Make sure the following options are checked:
    • Internet Services
    • Windows Firewall
    • System Restore
    • Security Center
    • Windows Update
  • Press "Scan".
  • It will create a log (FSS.txt) in the same directory the tool is run.
  • Please copy and paste the log to your reply.

Step 3
Download Security Check from here or 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.

In your next reply I would like to see:
  • FSS.txt from farbars service scanner
  • checkup.txt from security check
  • How is the computer running now?

Hi again.
You are in need of Service Pack 1 for Windows 7. It will close a bunch of holes that malware could use to re-enter your system,
Please go here to download the installer for SP1

You have 2 anti virus programs AVG 2013 and Microsoft Security Essentials installed. Having 2 AV programs is not recommended and may actually make your comptuer less safe.
You really need to uninstall one of them. Personally I would ditch the AVG program, as it's pretty much a resource hog.
If you choose to remove AVG, you will need to uninstall it by clicking on the start orb, selecting Control Panel, and clicking on Uninstall a program. Select AVG in that list and click Uninstall
After you uninsatll it, you will need to run the AVG removal tool from here, right click it and select Run as Administrator.
Follow the instructions and reboot when asked to.

If you choose to remove Microsoft Security Essentials instead, uninstall it by clicking on the start orb, selecting Control Panel, and clicking on Uninstall a program. Select Microsoft Security Essentials in that list and click Uninstall.

Having done all that --

Subject to no further problems :)

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset System Restore points:

  • Under the Custom Scans/Fixes box at the bottom, paste in the following


  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that
  • Go to control panel
  • Select folder options (Appearance > Folder options in category view)
  • Select the View Tab.
  • Under the Hidden files and folders heading select Do not show hidden files and folders.
  • Click Yes to confirm.
  • Click OK.

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

Upgrading Java:
  • Go to this site and click Do I have Java
  • It will check your current version and then offer to update to the latest version


To manually create a new Restore Point

  • Go to Control Panel and select System
  • Select System
  • On the left select System Protection and accept the warning if you get one
  • Select System Protection Tab
  • Select Create at the bottom
  • Type in a name i.e. Clean
  • Select Create

Now we can purge the infected ones

  • Go Start > All programs > Accessories > system tools
  • Right click Disc cleanup and select run as administrator
  • Select Your main drive and accept the warning if you get one
  • For a few moments the system will make some calculations
  • Select the More Options tab
  • In the System Restore and Shadow Backups select Clean up
  • Select Delete on the pop up
  • Select OK
  • Select Delete

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:
Posted Image
Malwarebytes. Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programs on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

To learn more about how to protect yourself while on the internet read our little guide How did I get infected in the first place ?

Keep safe :wave:
