Hi and Welcome!! :) My name is Jeff. I would be more than happy to take a look at your malware results logs and help you with solving any malware problems you might have. Logs can take a while to research, so please be patient and know that I am working hard to get you a clean and functional system back in your hands. I'd be grateful if you would note the following:

  • I will be working on your Malware issues, this may or may not, solve other issues you have with your machine.
  • The fixes are specific to your problem and should only be used for the issues on this machine.
  • Please continue to review my answers until I tell you your machine appears to be clear. Absence of symptoms does not mean that everything is clear.
  • It's often worth reading through these instructions and printing them for ease of reference.
  • If you don't know or understand something, please don't hesitate to say or ask!! It's better to be sure and safe than sorry.
  • Please reply to this thread. Do not start a new topic.

IMPORTANT NOTE : Please do not delete anything unless instructed to.

DO NOT use any TOOLS such as Combofix or HijackThis fixes without supervision.

Doing so could make your system inoperable and could require a full reinstall of your OS losing all your programs and data.

Vista and Windows 7 users:

These tools MUST be run from the executable (.exe) every time you run them

with Admin Rights (Right click, choose "Run as Administrator")

Stay with this topic until I give you the all clean post.

---------

Please download TDSSKiller

  • Double click TDSSKiller.exe
  • Press Start Scan
  • Do Not Attempt To Fix Anything Now. We just need to look over the report and be sure we are removing the correct
    items.
  • Attach the log in your next reply
    • A copy of the log will be saved automatically to the root of the drive (typically C:\)

Good job!

Download Combofix from the link below, and save it to your desktop.

Link

**Note: It is important that it is saved directly to your desktop**

If you get a message saying "Illegal operation attempted on a registry key that has been marked for deletion", please restart your computer.

Right-Click and Run as Administrator on ComboFix.exe & follow the prompts.

  • Please open Notepad (Start -> Run -> type notepad in the Open field -> OK) and copy and paste the text present inside the box below:

    ClearJavaCache::
    DDS::
    BHO: Expat Shield Class: {3706EE7C-3CAD-445D-8A43-03EBC3B75908} - C:\Program Files (x86)\Expat Shield\HssIE\ExpatIE.dll
    x64-BHO: Expat Shield Class: {3706EE7C-3CAD-445D-8A43-03EBC3B75908} - C:\Program Files (x86)\Expat Shield\HssIE\ExpatIE_64.dll
    Firefox::
    FF - ProfilePath - c:\users\Jenny\AppData\Roaming\Mozilla\Firefox\Profiles\aj84rors.default\
    FF - ExtSQL: 2012-11-19 09:37; {FD0ACDF6-72F4-4FE3-8411-6BDF7F1FCEA1}; c:\users\Jenny\AppData\Roaming\Mozilla\Firefox\Profiles\aj84rors.default\extensions\{FD0ACDF6-72F4-4FE3-8411-6BDF7F1FCEA1}.xpi
  • Save this as CFScript.txt and change the "Save as type" to "All Files" and place it on your desktop.
    CFScriptB-4.gif
  • 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".
  • 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. Post 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.

----------

Please post the new ComboFix log and let me know how your system is running. :)

Hi,

Good to hear!

I see that your Java software is out of date. Please go to Start >> Control Panel >> Programs and Features >> uninstall all versions of Java.

Now download and install the newest version from here >> http://java.com/en/download/index.jsp

-------------

Clear Java Cache

See this page for instructions on how to clear java's cache.

Go into the Control Panel and double-click the Java Icon. (looks like a coffee cup)

  • Under Temporary Internet Files, click the Delete Files button.
  • There are three options in the window to clear the cache - Leave ALL 3 Checked

    • Downloaded Applets
      Downloaded Applications
      Other Files

    [*]Click OK on Delete Temporary Files Window

    Note: This deletes ALL the Downloaded Applications and Applets from the CACHE.

    [*]Click OK to leave the Java Control Panel.

----------

Malwarebytes

Please open Malwarebytes, update it and then run a Quick Scan. Save the log that is created for your next reply.

----------

ESET Online Scanner

Go here to run an online scannner from ESET. Windows Vista/Windows 7 users will need to right click on their Internet Explorer shortcut, and select Run as Administrator

  • Note: For browsers other than Internet Explorer, you will be prompted to download and install esetsmartinstaller_enu.exe. Click on the link and save the file to a convenient location. Double click on it to install and a new window will open. Follow the prompts.
  • Turn off the real time scanner of any existing antivirus program while performing the online scan
  • Tick the box next to YES, I accept the Terms of Use.
  • Click Start
  • When asked, allow the activex control to install
  • Click Start
  • Make sure that the option Remove found threats is unticked and the Scan Archives option is ticked.
  • Click on Advanced Settings, ensure the options Scan for potentially unwanted applications, Scan for potentially unsafe applications, and Enable Anti-Stealth Technology are ticked.
  • Click Scan
  • Wait for the scan to finish
  • When the scan is done, if it shows a screen that says "Threats found!", then click "List of found threats", and then click "Export to text file..."
  • Save that text file on your desktop. Copy and paste the contents of that log as a reply to this topic.
  • Close the ESET online scan, and let me know how things are now.

Those entries found by ESET are fine....

Providing there are no other malware related problems...

IT APPEARS THAT YOUR LOGS ARE NOW CLEAN SO LETS DO A COUPLE OF THINGS TO WRAP THIS UP!!

This infection appears to have been cleaned, but I can not give you any absolute guarantees. As a precaution, I would go ahead and change all of your passwords as this is especially important after an infection.

----------

The following will implement some cleanup procedures as well as reset System Restore points:

Press the Windows key + R and this will open the Run box. Copy/paste the following text into the Run box as shown and click OK.

Combofix /Uninstall

(Note: There is a space between the ..X and the /U that needs to be there.)

----------

Any of the logs that you created for use in the forums or remaining tools that have not yet been removed can be deleted so they aren't cluttering up your desktop.

If you didn't already have it I would keep Malwarebytes AntiMalware though.

Here are some tips to reduce the potential for spyware infection in the future:

1. Internet Explorer. Even if you don't use it as your main browser it should be kept up-to-date because that is the browser Windows uses for updates.

Make your Internet Explorer more secure - This can be done by following these simple instructions:

  • From within Internet Explorer click on the Tools menu and then click on Options.
  • Click once on the Security tab
  • Click once on the Internet icon so it becomes highlighted.
  • Click once on the Custom Level button.
  • Change the Download signed ActiveX controls to Prompt
  • Change the Download unsigned ActiveX controls to Disable
  • Change the Initialize and script ActiveX controls not marked as safe to Disable
  • Change the Installation of desktop items to Prompt
  • Change the Launching programs and files in an IFRAME to Prompt
  • Change the Navigate sub-frames across different domains to Prompt
  • When all these settings have been made, click on the OK button.
  • If it prompts you as to whether or not you want to save the settings, press the Yes button.
  • Next press the Apply button and then the OK to exit the Internet Properties page.

2. FireFox. If you use Firefox, I recommend installing the following add-ons to help make your Firefox browser more secure:

NoScript

AdBlock Plus

3. Enable Protected Mode in Internet Explorer. This helps Windows Vista users stay more protected from attack by running Internet Explorer with restricted privileges as well as reducing the ability to write, alter or destroy data on your system or install malicious code. To make sure this is running follow these steps:

  • Open Internet Explorer
  • Click on Tools > Internet Options
  • Press Security tab
  • Select Internet zone then place check next to Enable Protected Mode if not already done
  • Do the same for Local Intranet, Trusted Sites and Restricted Sites and then press Apply
  • Restart Internet Explorer and in the bottom right corner of your screen you will see Protected Mode: On showing you it is enabled.

4. Use and update an anti-virus software - I can not overemphasize the need for you to use and update your anti-virus application on a regular basis. With the ever increasing number of new variants of malware arriving on the scene daily, you become very susceptible to an attack without updated protection.

5. Firewall

Using a third-party firewall will allow you to give/deny access for applications that want to go online. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a firewall in its default configuration can lower your risk greatly. I would personally only recommend using one of the following two below:

Online Armor Free

Agnitum Outpost Firewall Free

6. Make sure you keep your Windows OS current. Windows XP users can visit Windows update regularly to download and install any critical updates and service packs. Windows Vista/7 users can open the Start menu > All Programs > Windows Update > Check for Updates (in left hand task pane) to update these systems. Without these you are leaving the back door open.

7. WOT (Web of Trust) As "Googling" is such an integral part of internet life, this free browser add on warns you about risky websites that try to scam visitors, deliver malware or send spam. It is especially helpful 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. WOT has an add-on available for Firefox, Internet Explorer as well as Google Chrome.

8.Finally, I strongly recommend that you read How to Prevent Malware found here and also PC Safety and Security - What Do I Need?.

Please reply to this thread once more if you are satisfied so that we can mark the problem as resolved.
