I started a topic at:
http://www.bleepingcomputer.com/forums/t/225384/koobface-mbam-reports-multiple-infections/

and was referred here because my AV logs suggest a backdoor trojan is on my system here are the DDS logs I was asked to post if I wanted any help, I hope this is all correct. Thanks for reading, any and all help is appreciated.

My computer just keeps getting reinfected with various trojans, bots etc even when I perform a full scan with MBAM and set files to be deleted at boot-up.

Hello.

My name is Extremeboy and I will help you with your log.

2 Anti-virus/Firewall Programs Running Simultaenously Warning

I do not recommend that you have more than one anti virus or firewall product installed and running on your computer at a time. In addition to wasting resources, 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 Avast or Trend Micro Antivirus.

Please uninstall them until you are only running one antivirus using Add/Remove Programs.

Install Recovery Console and Run ComboFix

Note to readers of this post other than the starter of this thread:
ComboFix is a VERY POWERFUL tool which should NOT BE USED without guidance of an expert.

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

Link 1
Link 2
Link 3
  • 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 call it to stall.

Download and Run Scan with GMER

We will use GMER to scan for rootkits.This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop. Unzip/extract the file to its own folder. (Click here for information on how to do this if not sure. Win 2000 users click here.
  • Close any and all open programs, as this process may crash your computer.
  • Double click Posted Image or Posted Image on your desktop.
  • When you have done this, close all running programs.
    There is a small chance this application may crash your computer so save any work you have open.
  • Double-click on Gmer.exe to start the program. Right-click and select Run As Administrator... if you are using Vista
  • Allow the gmer.sys driver to load if asked.
    If it detects rootkit activity, you will receive a prompt (refer below) to run a full scan. Click NO..
    Posted Image
  • In the right panel, you will see several boxes that have been checked. Please UNCHECK the following:
    • Sections
    • IAT/EAT
    • Drives/Partition other than Systemdrive (typically C:\)
    • Show all (Don't miss this one!)
  • Posted Image
  • Click on Posted Image and wait for the scan to finish.
  • If you see a rootkit warning window, click OK.
  • Push Posted Image and save the logfile to your desktop.
  • Copy and Paste the contents of that file in your next post.

If GMER doesn't work in Normal Mode try running it in Safe Mode

Note: Do Not run any program while GMER is running
*Note*: Rootkit scans often produce false positives. Do NOT take any actions on "<--- ROOKIT" entries
