Hello oakparkmom,
  • Welcome to Bleeping Computer.
  • My name is fireman4it and I will be helping you with your Malware problem.

    Please take note of some guidelines for this fix:
  • Refrain from making any changes to your computer including installing/uninstall programs, deleting files, modifying the registry, and running scanners or tools.
  • If you do not understand any step(s) provided, please do not hesitate to ask before continuing.
  • Even if things appear to be better, it might not mean we are finished. Please continue to follow my instructions and reply back until I give you the "all clean".
  • In the upper right hand corner of the topic you will see a button called Watch Topic.I suggest you click it and select Immediate E-Mail notification and click on Proceed. This way you will be advised when we respond to your topic and facilitate the cleaning of your machine.

  • Finally, please reply using the ADD REPLY button in the lower right hand corner of your screen. Do not start a new topic. The logs that you post should be pasted directly into the reply, unless they do not fit into the post.

1.
I do not recommend that you have more than one anti virus product installed and running on your computer at a time. The reason for this is that if both products have their automatic (Real-Time) protection switched on, then those products which do not encrypt the virus strings within them can cause other anti virus products to cause "false alarms". It can also lead to a clash as both products fight for access to files which are opened again this is the resident/automatic protection. In general terms, the two programs may conflict and cause:
1) False Alarms: When the anti virus software tells you that your PC has a virus when it actually doesn't.
2) System Performance Problems: Your system may lock up due to both products attempting to access the same file at the same time.
Therefore please go to add/remove in the control panel and remove either Mcafee or Microsoft Securty Essentials.


2.
Spybot S&D or Ad-Aware are no longer recommended
  • mvps.org is no longer recommending Spybot S&D or Ad-Aware due to poor testing results. See here - (scroll down and read under Freeware Antispyware Products)
  • Further, most people don't understand Spybot's TeaTimer or how to use it and that feature can cause more problems than it's worth. TeaTimer monitors changes to certain critical keys in Windows registry but does not indicate if the change is normal or a modification made by a malware infection. The user must have an understanding of the registry and how TeaTimer works in order to make informed decisions to allow or deny the detected changes. Additionally, TeaTimer may conflict with other security tools which do a much better job of protecting your computer and even prevent disinfection of malware by those tools.
  • More effective alternatives are Malwarebytes Anti-Malware and SUPERAntiSpyware Free.



3.
Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.5.6.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.5.6.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.


4.
Install Recovery Console and Run ComboFix

This tool is not a toy. If used the wrong way you could trash your computer. Please use only under direction of a Helper. If you decide to do so anyway, please do not blame me or ComboFix.

Download Combofix from any of the links below, and save it to your desktop.

Link 1
Link 2
  • Close/disable all anti-virus and anti-malware programs so they do not interfere with the running of ComboFix. Refer to this page if you are not sure how.
  • Close any open windows, including this one.
  • Double click on ComboFix.exe & follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • If you did not have it installed, you will see the prompt below. Choose YES.
  • Posted Image
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Note:The Windows Recovery Console will allow you to boot up into a special recovery (repair) mode. This allows us to more easily help you
should your computer have a problem after an attempted removal of malware. It is a simple procedure that will only take a few moments of your time.

  • Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

    Posted Image
  • Click on Yes, to continue scanning for malware.
  • When finished, it will produce a report for you. Please post the contents of the log (C:\ComboFix.txt).
Leave your computer alone while ComboFix is running.
ComboFix will restart your computer if malware is found; allow it to do so.


Note: Please Do NOT mouseclick combofix's window while its running because it may cause it to stall.

Hello,

Update - my computer just did the Blue Screen of Death. What do I do?


Try and start it up again and see how it goes.


Lets try a couple of other things see how it goes.

1.
Re-Run aswMBR

  • Click Scan
  • On completion of the scan, click the FIXMBR button
  • There is a slight pause after clicking the 'Fix' button.
  • Wait for the tool to report 'Infection fixed successfully', now reboot the machine.
  • Rebooting the machine prematurely, before seeing this line will result in an incomplete fix.

    Note:After the 'Infection fixed successfully' message appears, the machine may became unresponsive. You may have to do a hard boot of your machine. That may be a side effect from the fix. All will be well after the reboot.
  • Save the log as before and post in your next reply.

2.
Please download Malwarebytes' Anti-Malware (v1.50) and save it to your desktop.
Download Link 1
Download Link 2Malwarebytes' 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 and double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to this Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • Malwarebytes 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 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.
  • Under the Scanner tab, make sure the "Perform Quick Scan" option is selected.
  • Click on the Scan button.
  • When 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, then click the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked and then 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.
  • 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 the database version and your operating system.
  • Exit Malwarebytes' when done.
Note: If Malwarebytes' encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes' from removing all the malware.

3.
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

Hello, oakparkmom.
Congratulations! You now appear clean! :cool:


Uninstall Combofix
  • Make sure that Combofix.exe that you downloaded is on your Desktop but Do not run it!
    o *If it is not on your Desktop, the below will not work.
  • Click on Posted Image then Run....
  • Now copy & paste the green bolded text in the run-box and click OK.

    ComboFix /Uninstall

    Posted Image

    <Notice the space between the "x" and "/".> <--- It needs to be there
    Windows Vista users: Press the Windows Key + R to bring the Run... Command and then from there you can add in the Combofix /Uninstall

  • Please advise if this step is missed for any reason as it performs some important actions:
    "This will uninstall Combofix, delete its related folders and files, reset your clock settings, hide file extensions, hide the system/hidden files and resets System Restore again.
    It also makes a clean Restore Point and flashes all the old restore points in order to prevent possible reinfection from an old one through system restore".


Are things running okay? Do you have any more questions?

System Still Slow?
You may wish to try StartupLite. Simply download this tool to your desktop and run it. It will explain any optional auto-start programs on your system, and offer the option to stop these programs from starting at startup. This will result in fewer programs running when you boot your system, and should improve preformance.
If that does not work, you can try the steps mentioned in Slow Computer/browser? Check Here First; It May Not Be Malware.

We Need to Clean Up Our Mess
  • Download OTC by OldTimer and save it to your desktop.
  • Double click Posted Image icon to start the program. If you are using Vista, please right-click and choose run as administrator
  • Then Click the big Posted Image button.
  • You will get a prompt saying "Being Cleanup Process". Please select Yes.
  • Restart your computer when prompted.



Recommendations
Below are some recommendations to lower your chances of (re)infection.
  • Install and maintain an outbound firewall
  • Install Spyware Blaster and update it regularly
    If you wish, the commercial version provides automatic updating.
  • Install the MVPs hosts file, and update it regularly
    You can use the HostMan host file manager to do this automaticly if you wish.
    For more information on the hosts file, and what it can do for you, you can view the Tutorial on the Hosts file
  • Install an Anti-Spyware program, and update it regularly
    Malware Byte's Anti Malware is an excellent Anti-Spyware scanner. It's scan times are usually under ten minutes, and has excellent detection and removal rates.
    SUPERAntiSpyware is another good scanner with high detection and removal rates.
    Both programs are free for non commercial home use but provide a resident and do not nag if you purchase the paid versions.
  • Keep Windows (and your other Microsoft software) up to date!
    I cannot stress how important this is enough. Often holes are found in Internet Explorer or Windows itself that require patching. Sometimes these holes will allow an attacker unrestricted access to your computer.

    If you are using Windows XP or earlier
    Visit the Microsoft Update Website and follow the on screen instructions to setup Microsoft Update. Also follow the instructions to update your system. Please REBOOT and repeat this process until there are no more updates to install!!

    If you are using Windows Vista
    • Click the "Start Menu" (or Windows Orb)
    • Click "All Programs"
    • Click "Windows Update"
    • On the left, choose "Change Settings"
    • Ensure that the checkbox "Use Microsoft Update" at the bottom of the window is checked.
    • Press OK and accept the UAC prompt.
      Note: You shouldn't need to check this checkbox every single time you update, only the first time.
    • Click "Check for Updates" in the upper left corner.
    • Follow the instructions to install the latest updates.
    • Reboot and repeat the "Check for Updates" until there are no more critical updates to install
  • Keep your other software up to date as well
    Software does not need to be made by Microsoft to be insecure. You can use the Secunia Online Software occasionally to help you check for out of date software on your machine.
  • Stay up to date!
    The MOST IMPORTANT part of any security setup is keeping the software up to date. Malware writers release new variants every single day. If your software updates don't keep up, then the malware will always be one step ahead. Not a good thing :(.

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.
