Hello and welcome to Bleeping Computer

My name is etavares and I will be working with you to fix your computer.

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

Please take note:

  • If you have since resolved the original problem you were having, we would appreciate you letting us know.
  • If you are unable to create a log because your computer cannot start up successfully please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.
  • Please tell us if you have your original Windows CD/DVD available.
  • If you are unable to perform the steps we have recommended please try one more time and if unsuccessful alert us of such and we will design an alternate means of obtaining the necessary information.
  • Once we start working together, please reply back within 3 days or this thread may be closed so we can help others who are waiting. If you will be unable to respond (e.g. vacation, travel, etc.), please let me know ahead of time.
  • Please refrain from running tools or applying updates other than those we suggest while we are cleaning up your computer. The reason for this is so we know what is going on with the machine at any time. Some programs can interfere with others and hamper the recovery process. Please also continue to work with me until I give you the all clear. Even if your computer appears to act better, you may still be infected.
  • If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • If you have already posted a log, please do so again as instructed below, as your situation may have changed.
  • Use the 'Add Reply' and add the new log to this thread.

We need to see some information about what is happening in your machine. Please perform the following scan:

We need to create an OTL report,
  • Please download OTL from this link.
  • Save it to your desktop.
  • Double click on the Posted Image icon on your desktop.
  • Click the "Scan All Users" checkbox.
  • Under the Custom Scan box paste this in:

    netsvcs
    msconfig
    drivers32 /all
    %systemroot%\system32\*.dll /lockedfiles
    %systemroot%\system32\*.sys /90
    %systemroot%\Tasks\*.job /lockedfiles
    %systemroot%\System32\config\*.sav
    %SYSTEMDRIVE%\*.*
    %systemroot%\system32\Spool\prtprocs\w32x86\*.dll
    %systemroot%\*. /mp /s
    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
    CREATERESTOREPOINT

  • Click the Quick Scan button.
  • The scan should take a few minutes.
  • Please copy and paste both logs in your reply.


Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice

Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


In your reply, please post both OTL logs and the GMER log. Thanks and again sorry for the delay.

Here are the logs. It is strange though that the ark.log is empty. I ran the scan and at the end it said something like "No modifications were found...." Is this how it was supposed to finish? I followed the directions exactly from the gmer page and I am confused why it would say the above mentioned message but the log come up blank. Below are the logs. #It would not let me post the ark.log it says "Error No file selected for upload" .I guessing it is due to being empty.

Hello, moddman.

Interesting. GMER should run on this as it's 32bit. No worries, we'll run aswMBR on it.

Also, the OTL log is missing several sections. We'll run an MBAM scan, then get a fresh DDS log since that was complete a while back.



Step 1

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.



Step 2

Please download aswMBR ( 511KB ) to your desktop.
  • Double click the aswMBR.exe icon to run it
  • Click the Scan button to start the scan
  • On completion of the scan, click the save log button, save it to your desktop and post it in your next reply.



Step 3

We need to see some information about what is happening in your machine. Please perform the following scan:
  • Download DDS by sUBs from one of the following links. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explaination about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Hello, moddman.




Trusted Zone Warning

Having trusted sites may not be a good idea. The reason why I say it's not a good idea is because the security settings for the internet is not extremely high and once you put a site in your trusted zone, basically almost anymore or thing, including hackers or other malicious software have full access to that site which can lead to hijacking that site and may even have access to your computer. Are you sure you trust a site to that degree?

It is recommended NOT to have ANY sites in your Trusted Zone unless the site requires it to function properly and you trust it very well. Other than that, it is not necessary for you to add any sites into the trusted zone. If you're not sure, and/or you do not need these in your trusted zone to facilitate access or you did not knowingly permit this access yourself, then please remove those sites from your trusted zone.

They can be accessed in Internet Explorer via Tools>>Internet Options>>Security>>Trusted Zone>>Sites. Remove if there are any there.



Step 1

I don't see an Anti Virus Program running on your machine
  • Download and install an antivirus program, and make sure that you keep it updated
    New viruses come out every minute, so it is essential that you have the latest signatures for your antivirus program to provide you with the best possible protection from malicious software.
    Two good antivirus programs free for non-commercial home use are Avast! and Antivir
    Note: You should only have one antivirus installed at a time. Having more than one antivirus program installed at once is likely to cause conflicts and may well decrease your overall protection as well as impairing the performance of your PC.



Step 2

Download SystemLook from one of the links below and save it to your Desktop.
Download Mirror #1
Download Mirror #2

If you have a 64-bit system, please download the 64 bit version from here:
SystemLook (64-bit)

  • Double-click SystemLook.exe to run it.
  • A blank Windows shall open with the title "SystemLook v1.0-by Jpshortstuff".
  • Copy and Paste the content of the following codebox into the main textfield under "File":
    :reg
    HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug\Debugger
    HKCU\Software\Microsoft\Windows Script\Settings\JITDebug
    HKLM\SOFTWARE\Microsoft\.NETFramework\DbgManagedDebugger
    
  • Please Confirm everything is copied and Pasted as I have provided above
  • Click the Look button to start the scan.
  • When finished, a notepad window will open with the results of the scan.
  • Please post this log in your next reply.


Note: The log can also be found on your Desktop entitled SystemLook.txt
2nd Note: The scan may take a while from several seconds to a minute or more depending on the number of files you have and how fast your computer can perform the task




Step 3

Please pull anything out of the recycle bin that you want to save. Part of this fix will empty temp files, and that does include the recycle bin.

Please download TFC by OldTimer and save it to your desktop.
alternate download link


  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If you are using Vista or Windows 7, right-click on the file and choose Run As Administrator.
  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.




Step 4

I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Push the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Push the Posted Image button.
  • Push Posted Image

Installed Antivirus, Checked IE8 Settings for Sites and those sites were in IE6 and are not showing in IE8. Could they have been defaulted in to IE8 if I updated straight from IE6 to IE8 even if they not showing in trusted IE8 trusted zites? Is there a way to take them out of this grandfathered in code? Here are the logs.

Hello, moddman.
Let's go up one step in the registry, that one didn't work.

We can script out the trusted zone in a bit.

Download SystemLook from one of the links below and save it to your Desktop.
Download Mirror #1
Download Mirror #2

If you have a 64-bit system, please download the 64 bit version from here:
SystemLook (64-bit)

  • Double-click SystemLook.exe to run it.
  • A blank Windows shall open with the title "SystemLook v1.0-by Jpshortstuff".
  • Copy and Paste the content of the following codebox into the main textfield under "File":
    :reg
    HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug
    HKCU\Software\Microsoft\Windows Script\Settings
    HKLM\SOFTWARE\Microsoft\.NETFramework
    
  • Please Confirm everything is copied and Pasted as I have provided above
  • Click the Look button to start the scan.
  • When finished, a notepad window will open with the results of the scan.
  • Please post this log in your next reply.


Note: The log can also be found on your Desktop entitled SystemLook.txt
2nd Note: The scan may take a while from several seconds to a minute or more depending on the number of files you have and how fast your computer can perform the task

The good news is that those entries are fine. Sometime malicious programs edit those to launch in place of a legit debugger. It's set to auto which means it launches when the app crashes. That's the default setting. What applications are crashing and causing this? I went back and looked at the other 2-3 threads you had about this..it sounds like you've had .NET issues for month or so.

The application is Tiny Tuner which depends on Net 2.0 in order to work. It opens up but when it trys to load the database it gives me the error that I posted. There is a debug folder in the main program folder that contains the tiny tuner.exe and if I use it from that folder I do not get the error and the database loads just fine. It happens when I use the main folder that is meant for use when using this program. I can post the link if you want to check out this particular app.

As far as the net issues, I had net 2.0 service pack one installed with out having net 2.0 installed first. The tiny tuner wouldn't open at all due to this issue. I used the net uninstaller tool and started from scratch. Net 1.0, Net 1.1, Net 2.0, Net 3.5, etc. Do you think the uninstaller caused this issue I'm currently having?
