Hello, domipj

Welcome to the Emsisoft Support Forums. My name is Kevin, and I will be helping you fixing your problems.

Take note of some guidelines for this support request:

  • Refrain from making any changes to your computer including installing/uninstall programs, deleting files, modifying the registry, and running scanners or tools. Doing so could cause changes to the directions I have to give you and prolong the time required. Further more, you should not be taking any advice relating to this computer from any other source throughout the course of this fix.
  • If you do not understand any step(s) provided, please do not hesitate to ask before continuing. I would much rather clarify instructions or explain them differently than have something important broken.
  • 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". We do not want to clean you part-way, only to have the system re-infect itself.
  • Do not start a new topic. The logs that you post should be pasted directly into the reply. Only attach them if requested or if they do not fit into the post.
  • Set your system to show all files.
    Click Start, open My Computer, select the Tools menu and click Folder Options.
    Select the View Tab. Under the Hidden files and folders heading, select Show hidden files and folders.
    Uncheck: Hide file extensions for known file types
    Uncheck the Hide protected operating system files (recommended) option.
    Click Yes to confirm.

Read and follow these instructions carefully.

Stay in your original thread. Do not start new threads for the same support issue.

Read carefully and follow these steps.

  • Download TDSSKiller and save it to your Desktop.
  • Double-click on TDSSKiller.exe to run the application.

    tdss3.png
  • Click on the Start Scan button to begin the scan and wait for it to finish.
    NOTE: Do not use the computer during the scan!
  • During the scan it will look similar to the image below:
    tdss4.jpg
  • When it finishes, you will either see a report that no threats were found like below:
    tdss5.jpg
    If no threats are found at this point, just click the Report selection on the top right of the form to generate a log. A log file report will pop which you can just close since the report file is already saved.
  • If any infection or suspected items are found, you will see a window similar to below:
    tdss7.jpg
    • If you have files that are shown to fail signature check do not take any action on these. Make sure you select Skip. I will tell you what to do with these laater. They may not be issues at all.
    • If Suspicious objects are detected, the default action will be Skip. Leave the default set to Skip.
    • If Malicious objects are detected, they will show in the Scan results. TDSSKiller automatically selects an action (Cure or Delete) for malicious objects
      Make sure that Cure is selected. Important! - If Cure is not available, please choose Skip instead. Do not choose Delete unless instructed to do so.

    [*]Click Continue to apply selected actions.

    [*]A reboot may be required to complete disinfection. A window like the below will appear:

    tdss6.jpg

    Reboot immediately if TDSSKiller states that one is needed.

    [*]Whether an infection is found or not, a log file should have already been created on your C: drive (or whatever drive you boot from) in the root folder named something like TDSSKiller.2.1.1_27.12.2009_14.17.04_log.txt which is based on the program version # and date and time run.

    [*]Attach this log to your next reply.

Download ComboFix from one of these locations:

Save as Combo-Fix.exe during the download. ComboFix must be renamed before you download to your Desktop

Link 1

Link 2

* IMPORTANT !!! Save ComboFix to your Desktop

  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools
    See HERE for help
  • Double click on Combo-Fix & 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.
  • 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: (This applies to Windows XP systems only) If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

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

whatnext.png

Click on Yes, to continue scanning for malware.

When finished, ComboFix will produce a log.

Note:

1. Do not mouseclick combofix's window while it's running. That may cause it to stall!

2. Remember to re-enable your anti-virus and anti-spyware before reconnecting to the Internet.

Attach logs for: (USE THE "MORE REPLY OPTIONS" BUTTON TO BE ABLE TO DO THIS)

  • ComboFix (C:\combofix.txt)

Let me know of any problems you may have encountered with the above instructions and also let me know how things are running now!

Read all these directions before proceeding.

When you have the .ISO file downloaded, you need to create a bootable disk or flash drive with it, using a clean PC to do that. The .ISO file is a disk image. It should NOT be burned as a regular file. You need a program like ImgBurn that can burn an .ISO image. I think a CD is best as there is no way anything can write on it after it is made, but the USB may be more convenient and easier.

Be sure to read these:

Download Kaspersky Rescue Disk 10

How to record Kaspersky Rescue Disk 10 to an USB device and boot my computer from it?

How to record Kaspersky Rescue Disk 10 to a CD/DVD and boot my computer from the disk?

Summarizing:

  • Go to a clean PC.
  • Download the .iso image file.
  • Create a CD (or flash drive if you prefer).
  • At the infected PC: put the disk in the drive and reboot.

Follow the directions here, but you will find some differences.

Familiarize yourself with How to create a report file in Kaspersky Rescue Disk 10?

Print the following directions:

Boot from Kaspersky Rescue Disk 10:

  • Restart your computer and put the disk in the drive while booting.
  • Press any key. A loading wizard will start (you will see the menu to select the required language). If you do not press any key in 10 seconds, the computer boots from hard drive automatically.
  • Select the required interface language using the arrow-keys on your keyboard.
  • Press the Enter key on the keyboard.
  • In the start up wizard window that opens, select the Kaspersky Rescue Disk. Graphic Mode
  • Click Enter.
  • Click 'A' to accept the agreement.
  • Select operating system from dropdown menu (select Windows whatever)
  • Select Objects to scan: check Disk boot sectors, Hidden startup objects, C:
  • Click My Update Center and update if any available
  • Back to other tab and click Start Object Scan. (This could take several hours to finish)
  • When scan has completed save a report:
    • On the upper part of the Kaspersky Rescue Disk window, click on the Report link.
    • On the bottom right hand corner of the Protection status - Kaspersky Rescue Disk window, click on the Detailed Report button.
    • On the upper right hand corner of the Detailed report window, click on the Save button.
    • After clicking Detailed Report and 'SAVE', a browse window opens.
    • Double-click on the \
    • Click 'disks'.
    • All your drives will be shown and you can easily double-click C and save the report to C:\KasperskyRescueDisk10.txt.
    • Click on the Save button.
    • The report has been saved to the file.

    [*]Remove the disk from the drive (or disconnect USB) and reboot normally.

Attach KasperskyRescueDisk10.txt to your reply.

Looks like KAV10 found and repaired a boot sector infection on 2 other drives, everything else was in the TDSSKiller Quarantine folder.

Let me know the results of the EAM scan.

Your last set of logs look fine.

Unless you are having problems, it is time to do the final steps.

Now to remove most of the tools that we have used in fixing your machine:

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

Clean up with OTL:

  • Double-click OTL.exe to start the program.
  • Close all other programs apart from OTL as this step will require a reboot
  • On the OTL main screen, press the CLEANUP button
  • Say Yes to the prompt and then allow the program to reboot your computer.

Delete the following from your Desktop (If they exist)

TDSSKiller.exe

Anything else I had you use

Delete the following files: (If they exist)

C:\ComboFix.txt

Delete the following folders: (If they exist)

C:\ComboFix

C:\Qoobox

C:\TDSSKiller_Quarantine

Empty the Recycle Bin

Download to your Desktop:

- CCleaner Portable

  • UnZip CCleaner Portable to a folder on your Desktop named CCleaner

Run CCleaner

  • Open the CCleaner Folder on your Desktop and double click CCleaner.exe (32-bit) or CCleaner64.exe (64-bit)
  • The following should be selected by default, if not, please select:
    4l5a4i.png
  • Click 16jox2o.png and choose 5x3nu8.gif
  • Uncheck amuvj8.gif
  • Then go back to 2jb4qyb.gif and click nf47ev.gif to run it.
  • Exit CCleaner.

Turn off System restore to flush all your restore points then turn system restore back on. See How To Enable and Disable System Restore.

You can delete and uninstall any programs I had you download, that you do not wish to keep on the system.

Run Windows Update and update your Windows Operating System.

Run the Secunia Online Software Inspector, this will inspect your system for software that is out-of-date and in need of updating. Update anything program/application detected as being out-dated.
