Ok. I'm infected big time with Admarket, a couple of back doors, and God knows what.

I have ran the following, with no luck of removing

McAfee
SpyBot
Ad-Aware
Dr. Web
Hi-Jack This
TrendMicro House Call
TrendMicro Rootkit Buster
A2 HiJackFree

I have been reading through the board a bit, so I have a basic understanding of the tools and methods. I just need a walk through to do something else that I've been missing. I am will to rerun whatever program needed.

I'll wait for a reply.

Please download hosts.zip and save it to your Desktop.
Be sure to read and print out these Install Instructions with screenshots for the MVPS HOSTS File if you need them.
  • Extract (unzip) the file to its own folder C:\hosts. (click here if you're not sure how to do this. Vista users refer to these instructions.)
  • Open up the hosts folder and double-click on the mvps.bat file to run the script.
  • When running the mvps.bat file you may see a DOS window indicating the Previous version was saved and renamed...Press any key to continue...
  • Press any key and the DOS windows will close.
  • The script will rename your present HOSTS file to HOSTS.MVP and copy the new HOSTS file to the correct location on your system.
  • If any installed security programs provide an alert about changes to the HOSTS file, allow the change.
  • You can read more about what we are doing in Blocking Unwanted Parasites with a Hosts File.
Note: You may have to overwrite the hosts file in "Safe Mode" if you get "an access denied message" when trying to do it in normal mode.

If you encounter a problem with the zipped version, try using an alternative zipping tool like 7zip or ExtractNow. If you still encounter problems, then use the MVPS HOSTS File text version. Go to File in the top menu and select "Save As", then save hosts.txt to your desktop. Rename it hosts without an extension. Go to the folder containing your existing HOSTS file and rename it HOSTS.MVP. Then copy the hosts file on your desktop into the same folder where you renamed the existing file.

-- Note: If using Vista or Windows 7, be aware that they require special instructions.Please download Malwarebytes Anti-Malware (v1.44) 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.

Please download TDSSKiller.zip and save it to your Desktop.
Be sure to print out and follow the instructions provided on that same page for performing a scan.
  • Extract (unzip) the file to your desktop and make sure TDSSKiller.exe (the contents of the zipped file) is on the Desktop itself, not within a folder on the desktop. (click here if you're not sure how to do this. Vista users refer to these instructions.)
  • Double-click on TDSSKiller.exe to run the tool.
  • If malicious services or files have been detected, the utility will prompt to reboot the PC in order to complete the disinfection procedure. Please reboot when prompted.
  • After reboot, the driver will delete malicious registry keys and files as well as remove itself from the services list.
IMPORTANT NOTE: One or more of the identified infections was related to a nasty variant of the TDSS/TDL3 rootkit. Rootkits, backdoor Trojans, Botnets, and IRCBots are very dangerous because they compromise system integrity by making changes that allow it to be used by the attacker for malicious purposes. Rootkits are used by Trojans to conceal its presence (hide from view) in order to prevent detection of an attacker's software and make removal more difficult. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. They can disable your anti-virus and security tools to prevent detection and removal. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:If your computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. They should be changed using a clean computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:Although the rootkit was identified and may be removed, your machine has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if the malware appears to have been removed. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired so you can never be sure that you have completely removed a rootkit. The malware may leave so many remnants behind that security tools cannot find them. Tools that claim to be able to remove rootkits cannot guarantee that all traces of it will be removed. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

Thank you for your help. Unfortunately. I had Dr. Web set-up to delete infected files, and it deleted sys files and I can't boot into my computer. Everytime I boot, I get a BSOD. I've done everything I know to do to resurrect it, with no luck. Looks like I have no choice but to to a reinstall.

Thank you again. :thumbsup:

These are links to Anti-virus vendors that offer free LiveCD or Rescue CD utilities that are used to boot from for repair of unbootable and damaged systems, rescue data, scan the system for virus infections. Burn it as an image to a disk to get a bootable CD. All (except Avira) are in the ISO Image file format. Avira uses an EXE that has built-in CD burning capability.If you are not sure how to burn an image, please read How to write a CD/DVD image or ISO. If you need a FREE utility to burn the ISO image, download and use ImgBurn.

Note: In order to use a rescue disk, the boot order must be set to start from the CD-ROM drive. If the CD is not first in the boot order, the computer will attempt to start normally by booting from the hard drive. The boot order is a setting found in the computerís BIOS which runs when it is first powered on. This setting controls the order that the BIOS uses to look for a boot device from which to load the operating system. The default will normally be A:, C:, CD-ROM. Different computers have different ways to enter the BIOS. If you're not sure how to do this, refer to:Your decision as to what action to take should be made by reading and asking yourself the questions presented in the "When should I re-format?" and "...Now What Do I Do?" links previously provided. As already said, in some instances an infection may leave so many remnants behind that security tools cannot find them and your system cannot be completely cleaned, repaired or trusted. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore with a vendor-specific Recovery Disk or Recovery Partition removes everything and is the safest action but I cannot make that decision for you.

Should you decide to reformat and you're not sure how to do that or need help, please review:These links include step-by-step instructions with screenshots:Vista users can refer to these instructions:Don't forget you will have to go to Microsoft Update and apply all Windows security patches after reformatting.

Note: If you're using an IBM, Sony, HP, Compaq, Toshiba, Gateway or Dell machine, you may not have an original XP CD Disk. By policy Microsoft no longer allows OEM manufactures to include the original Windows XP CD-ROM on computers sold with Windows preinstalled. Instead, most computers manufactured and sold by OEM vendors come with a vendor-specific Recovery Disk or Recovery Partition for performing a clean "factory restore" that will reformat your hard drive, remove all data and restore the computer to the state it was in when you first purchased it. Also be sure to read Technology Advisory Recovery Media. If the recovery partition has become infected, you will need to contact the manufacturer, explain what happened and ask them to send full recovery disks to use instead..

Reformatting a hard disk deletes all data. Should you decide to reformat or do a factory restore due to malware infection, you can back up all your important documents, personal data files, photos to a CD or DVD drive, not a flash drive or external hard drive as they may become compromised in the process. The safest practice is not to backup any executable files (*.exe), screensavers (*.scr), autorun (.ini) or script files (.php, .asp, .htm, .html, .xml ) files because they may be infected by malware. Avoid backing up compressed files (.zip, .cab, .rar) that have executables inside them as some types of malware can penetrate compressed files and infect the .exe files within them. Other types of malware may even disguise itself by hiding a file extension or adding to the existing extension as shown here (click Figure 1 to enlarge) so be sure you look closely at the full file name. If you cannot see the file extension, you may need to reconfigure Windows to show file name extensions. Then make sure you scan the backed up data with your anti-virus prior to to copying it back to your hard drive.

If your CD/DVD drive is unusable, another word of caution if you are considering backing up to an external usb hard drive as your only alternative. External drives are more susceptible to infection and can become compromised in the process of backing up data. I'm not saying you should not try using such devices but I want to make you aware of all your options and associated risks so you can make an informed decision if its worth that risk.

Also see How to use Ubuntu Live CD to Backup Files from your dead Windows Computer. Again, do not back up any data with the following file extensions: exe, .scr, .ini, .htm, .html, .php, .asp, .xml, .zip, .rar, .cab as they may be infected.

If you need additional assistance with reformatting or partitioning, you can start a new topic in the appropriate Windows Operating System Subforum.

Wow! I didn't even think about emergency disks. Thank you for the links! I'm trying the Avira now. This might take a little time to run through these. As soon as I find out something, I'll post again.

They are worth a try. Even if not successful, its still a good learning experience.
