    Well, this folder appear like twice every month and I don't remember how I got it. I just delete the folder, run CCleaner registry fix, run Malwarebytes, run AdwCleaner, run HitmanPro and somehow the problem is still there.

    Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer.

    1. I will be working on your Malware issues. This may or may not solve other issues you have with your machine.
    2. The fixes are specific to your problem and should only be used for this issue on this machine.
    3. If you don't know or understand something, please don't hesitate to ask.
    4. Please DO NOT run any other tools or scans while I am helping you.
    5. It is important that you reply to this thread. Do not start a new topic.
    6. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
    7. Absence of symptoms does not mean that everything is clear.

    If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line.
    *************************************************************************
    One or more of the identified infections is a backdoor trojan.

    This allows hackers to remotely control your computer, steal critical system information and Download and Execute files

    Read this article: Danger: Remote Access Trojans.

    If your computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay and forums. You should consider them to be compromised. They should be changed by using a different computer and not the infected one! If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach.

    I would counsel you to disconnect this PC from the Internet immediately.

    Though the Trojan 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 attempt to clean this machine but i can't guarantee that it will be 100% secure afterwards.

    Should you have any questions, please feel free to ask.

    Please let us know what you have decided to do in your next post

      Format and reinstall the OS sounds like a last resort. Can you show me how to clean up this computer for the moment?

          Whatever will work for you. Let's do some clean up.

          Click Start> Computer> right click the C Drive and choose Properties> enter
          Click Disk Cleanup from there.



          Click OK on the Disk Cleanup Screen.
          Click Yes on the Confirmation screen.



          This runs the Disk Cleanup utility along with other selections if you have chosen any. (if you had a lot System Restore points, you will see a significant change in the free space in C drive)
          *********************************************
          This step will remove all cleaning tools we used, it'll reset restore points (so you won't get reinfected by accidentally using some older restore point) and it'll make some other minor adjustments...
          This is a very crucial step so make sure you don't skip it.
          Download DelFix by Xplode to your desktop. Delfix will delete all the used tools and logfiles.

          Double-click Delfix.exe to start the tool.
          Make sure the following items are checked:
          • Activate UAC (optional; some users prefer to keep it off)
          • Remove disinfection tools
          • Create Registry backup
          • Purge System Restore Points
          • Re-set system settings
          Now click "Run" and wait patiently.
          Once finished a logfile will be created. You don't have to attach it to your next reply.
          ********************************************
