Hi,

Please do the following:

  • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before following the steps below.
  • They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
Copy/paste the text inside the Codebox below into notepad:

Here's how to do that:
Click Start > Run type Notepad click OK.
This will open an empty notepad file:

Copy all the text inside of the code box - Press Ctrl+C (or right click on the highlighted section and choose 'copy')

Folder::
C:\Program Files\ReferenceBoss_1p
C:\Program Files\Windows iLivid Toolbar

ClearJavaCache::

Now paste the copied text into the open notepad - press CTRL+V (or right click and choose 'paste')

Save this file to your desktop, Save this as "CFScript"


Here's how to do that:

1.Click File;
2.Click Save As... Change the directory to your desktop;
3.Change the Save as type to "All Files";
4.Type in the file name: CFScript
5.Click Save ...

Posted Image
  • Referring to the screenshot above, drag CFScript.txt into ComboFix.exe.
  • ComboFix may request an update; please allow it.
  • ComboFix will now run a scan on your system. It may reboot your system when it finishes. This is normal.
  • When finished, it shall produce a log for you.
  • Copy and paste the contents of the log in your next reply.

CAUTION: Do not mouse-click ComboFix's window while it is running. That may cause it to stall.


NEXT


  • Press the Win key + R to open a run box, then copy/paste the following single-line command into the Run box and click OK:

    C:\Qoobox\Add-Remove Programs.txt

  • A text file should open.
  • Post the contents of that file in your next reply.

Hello. I have run combofix, and after the reboot it has been sitting on the preparing log report screen for about 15 mins. The windows explorer has crashed 4 times during the wait. Should I rerun combofix? Thank you.

Below I have included a number of recommendations for how to protect your computer against malware infections.

  • It is good security practice to change your passwords to all your online accounts on a fairly regular basis, this is especially true after an infection. Refer to this Microsoft article
    Strong passwords: How to create and use them
    Then consider a password keeper, to keep all your passwords safe. KeePass is a small utility that allows you to manage all your passwords.

  • Keep Windows updated by regularly checking their website at :
    http://windowsupdate.microsoft.com/
    This will ensure your computer has always the latest security updates available installed on your computer.

  • Make Internet Explorer more secure
    • Click Start > Run
    • Type Inetcpl.cpl & click OK
    • Click on the Security tab
    • Click Reset all zones to default level
    • Make sure the Internet Zone is selected & Click Custom level
    • In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls) to "Prompt", and ("Initialize and Script ActiveX controls not marked as safe") to "Disable".
    • Next Click OK, then Apply button and then OK to exit the Internet Properties page.

  • Download TFC to your desktop
    • Close any open windows.
    • Double click the TFC icon to run the program
    • TFC will close all open programs itself in order to run,
    • Click the Start button to begin the process.
    • Allow TFC to run uninterrupted.
    • The program should not take long to finish it's job
    • Once its finished it should automatically reboot your machine,
    • if it doesn't, manually reboot to ensure a complete clean
    It's normal after running TFC cleaner that the PC will be slower to boot the first time.

  • WOT, Web of Trust, warns you about risky websites that try to scam visitors, deliver malware or send spam. Protect your computer against online threats by using WOT as your front-line layer of protection when browsing or searching in unfamiliar territory. WOT's color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites:
    • Green to go
    • Yellow for caution
    • Red to stop
    WOT has an addon available for both Firefox and IE

  • Keep a backup of your important files - Now, more than ever, it's especially important to protect your digital files and memories. This article is full of good information on alternatives for home backup solutions.

  • ERUNT (Emergency Recovery Utility NT) 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.

  • In light of your recent issue, I'm sure you'd like to avoid any future infections. Please take a look at this well written article:
    PC Safety and Security--What Do I Need?.


Thank you for your patience, and performing all of the procedures requested.

Please respond one last time so we can consider the thread resolved and close it, thank-you.
