Hi:

I have an HP HDX 16 running windows 7.  About 6 weeks ago I started having problems with my computer slowing down and then becoming non-functional, so I would have to shut it down and start over.  I ran malware bytes in safe mode but found nothing.  This has happened several times - each time worse.  I reran malware - again nothing.  I tried testing my hard drive with the built in diagnostic, but it says my hard drive is perfect.  Hmmm.  anyway, I decided that rather than try a bunch of stuff on my own, I would follow your step-by=step procedure to see if I have a malware problem.  I have attached the two files from dds you asked for.

 

Thanks for your help.  I await your brilliance!

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:
  • The fixes are specific to your problem and should only be used for the issues on this machine.
  • 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.
  • If you happen to have a flash drive/thumb drive please have that ready in the event that we need to use it.
  • Please be sure to subscribe to this topic so that you can see when there are new responses.
  • IMPORTANT NOTE : Please do not delete, download or install anything unless instructed to do so.
    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 operating system and losing all your programs and data.


    Having said that.... vegeta_zps7f4345cf.gifLet's get going!!
    ----------

    aswmbr-1-1.jpg
  • Please download aswMBR to your desktop.
  • Double click the aswMBR icon to run it.
  • Click the Scan button to start scan.
  • If you are asked to update the Avast Virus database please allow it to do so.
  • When it finishes, press the save log button, save the logfile to your desktop and attach its contents in your next reply.

thanks so much!  I ran the scan and have attached the results.  It took 2 minutes.  Something is wrong - am I doing something wrong?

Started the scan again and it crashed after about 20 minutes so I could not save the log.  I did a screen capture so you could read, and have attached as a jpeg.Attached File  screensave.jpg   90.58KB   2 downloads

Now what???? Do you think this could be a hard drive or memory problem?

I can not say with 100% accuracy at this point what the problem is but it may be we are dealing with the ZeroAccess rootkit infection.

 

 

ComboFix
 
Download Combofix from the link below, and save it to your desktop.  
 
**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.
 
--------------------------------------------------------------------
 
IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
 
--------------------------------------------------------------------
 
Right-Click and Run as Administrator on ComboFix.exe & follow the prompts.
  • When finished, it will produce a report for you.  
  • Please post the C:\ComboFix.txt for further review.

    Hi:

    I've run Combofix and have the log attached.  I couldn't find a directory named c:/combofix, but I had saved it on my desktop before closing, so here it is.

    I am very eager to hear from you, and hopeful that my computer isn't dying!

    Thanks so much for your help.

    ComboFix

    • 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: DefaultTab Browser Helper: {7F6AFBF1-E065-4627-A2FD-810366367D01} - C:\Users\CH\AppData\Roaming\DefaultTab\DefaultTab\DefaultTabBHO.dll
    Trusted Zone: $talisma_url$
    • 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.
     
    Post the new ComboFix log and let me know how your system is running now.

    My computer appears to be running well, but my problems occur after the computer  has been on for a while and I have been working with several programs.  However, today (after the first combofix scan) I ran the computer all day and didn't have a problem. So I think there is a huge improvement after the first ComboFix.  I am hoping...

     

    Question: did I have a virus?  I noticed in the first CF Log there were a series of files deleted (c:\windows\SysWow64\~GLH000c.TMP etc.) that I didn't recognize.  I googled them and found they could be problematic - or not (like life). But i can't interpret a good portion of the log; and i would really like to know if I had (or still have) a virus. Also, what did we do to the computer with the script I copied?

     

    Thanks for your help.  I have attached the second combofix file for your review.  I am hoping I am clean.  You've been great and I really appreciate your technical wisdom.

    Hi,

    Yes you had a few viruses on your system. How or when they got there is really hard to tell.
    -------------

    java-1.jpg 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
    -------------

    java-1.jpgClear 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.
    • ----------

      mbam-3.jpg 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.

    I have attached the mbam file, but nothing was found. Unfortunately, I didn't save the list of threats from eset - I thought I was going back to the first page listing the results, but when I clicked, it took me to the end and I couldn't get back to the results.  However, the threats deleted were:

     

    an exe file for an iso burner software

    an exe file for firefox

     

    So.. my questions for you are:

     

    I usually do not use Windows Defender, as Kasperksy recommends (or did recommend) turning it off (conflicts).  Should I turn it back on?

    Should I delete combofix (following instructions on your site?

    Am I now clean?

     

    Thanks again for your guidance.  I am thrilled to be back in operation.

    Hi,
     

    I usually do not use Windows Defender, as Kasperksy recommends (or did recommend) turning it off (conflicts).  Should I turn it back on?

    Nope...you should be fine.
     
     
    Providing there are no other malware related problems...

    Vegeta.gifIT APPEARS THAT YOUR LOGS ARE NOW CLEAN

    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 text 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.)

    CF.jpg
    ----------

    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 did not have Malwarebytes Antimalware before, I would keep it and run it weekly.
    ----------

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

    1. 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. 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.

      4. 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. **There are firewalls that could be downloaded and used but I would personally only recommend using one of the following two below:
      Online Armor Free
      Agnitum Outpost Firewall Free

      5. 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.

      6. 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.

      7. Finally, I strongly recommend that you read Miekiemoes' great advice How to prevent malware.

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

    It appears that this issue is resolved, therefore I am closing the topic. If that is not the case and you need or wish to continue with this topic, please send me or any Moderator a Personal Message (PM) that you would like this topic re-opened.
