Posted 31 January 2009 - 04:10 PM

According to Adaware I have a Win32Backdoor:TDSS worm. As other members have indicated it cannot be removed with conventional A/V software and it blocks access to sites like BC, Lavasoft and Spybot. I have acquired the software indicated in posted remedies, but do not know how or what to use to gt a DDS file if and when I should ever need one. I have run HJT and am waiting instructions before launching Combofix

Hi

My name is Extremeboy (or EB for short), and I will be helping you with your log.

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.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine. If you have not done so, include a description of your problem, along with any steps you may have performed so far.

If you do not make a reply in 5 days, we will need to close your topic.

You may want to keep the link to this topic in your favourites. Alternatively, you can click the Posted Image button at the top bar of this topic and Track this Topic. The topics you are tracking can be found here.

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. 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.
  • Please reply using the Posted Image 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.
  • Old topics are closed after 3 days with no reply, and working topics are closed after 5 days. If for any reason you cannot complete instructions within that time, that's fine, just post back here so that we know you're still here.


Posted ImageBackdoor Threat

IMPORTANT NOTE: Unfortunatly One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.

Install Recovery Console and Run ComboFix

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

Link 1
Link 2

  • 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.
  • Download gmer.zip and save to your desktop.
    Alternate Download Site 1
  • 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.
  • When you have done this, disconnect from the Internet and 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.
  • Allow the gmer.sys driver to load if asked.
  • If it gives you a warning at program start about rootkit activity and asks if you want to run a scan...click NO.

After the reboot, run Gmer again and click on the Rootkit tab.
  • Look at the right hand side (under Files) and uncheck all drives with the exception of your C drive.
  • Make sure all other boxes on the right of the screen are checked, EXCEPT for Show All.

Extremeboy,
Thanks for your post and your advice.

Earlier today I becamea a little impatient when I saw I was still #37 on the wait list. So, I tried to follow another path outlined for someone with the same trojan. The first step was to install mbam.exe. I couldn't get it to install so I reformatted my HD and ....

I know you guys are working your touches off trying to solve everyone's problems - it is much appreciated, truly.

However, I'll probably be back in the, hopefully, distant future.

Thanks again.

Palladin

I considr the file closed.

Hello.

Thanks for letting me know. Format/Reinstall is a good option. I would of done the same if it were my computer. just some prevention tips:

Install an AntiVirus Software

It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

See this link for a listing of some online & their stand-alone antivirus programs:
Virus, Spyware, and Malware Protection and Removal Resources

Some Free Anti-Virus software I recommend are: Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

Install a Firewall

I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

For a tutorial on Firewalls and a listing of some available ones see the link below:
Understanding and Using Firewalls

Some Firewall programs I recommend to others are:
Update your Firewall Program - It is imperitive that you update your Firewall at least once a week (Even more if you wish). If you do not update your firewall then it will not be able to catch any of the new variants that may come out.

Preventing Infections in the Future

Please also have a look at the following links, giving some advice and Tips to protect yourself against malware and reduce the potential for re-infection:
  • Avoid gaming sites, underground web pages, pirated software sites, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.
Disable Autorun on Flash-Drive/Removable Drives

When is AUTORUN.INF really an AUTORUN.INF?

USB worms work by creating a file called AUTORUN.INF on the root of USB drives. These INF files then use Autorun or Autoplay (not the same thing!) to execute themselves either when the stick is inserted, or more commonly, when the user double-clicks on the USB drive icon from My Computer (Windows Explorer)...


Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. Read USB-Based Malware Attacks and Please disable Autorun asap!.

If using Windows Vista, please refer to:
"Disable AutoPlay in Windows Vista"
"Preventing AutoPlay with Local Group Policy Editor or AutoPlay options panel"

Note: When Autorun is disabled, double-clicking a drive which has autorun.inf in its root directory may still activate Autorun so be careful.

Vist the WindowsUpdate Site Regularly

I recommend you regularly visit the Windows Update Site!
  • Lots of Hacking/Trojans use the methods found (plugged by the updates) that have not been stopped by people not updating.
  • By updating your machine, you have one less headache! Posted Image
  • Update ALL Critical updates and any other Windows updates for services/programs that you use.
  • If you wish, you can also use automatic updates. This is a good thing to have if you want to be up-to-date all the time, but can also be a bit of an annoyance due to its handling and the sizes of the updates. If you wish to turn on automatic updates then you will find here is a nice little article about turning on automatic updates.
  • Note that it will download them for you, but you still have to actually click install.
  • If you do not want to have automatic updates turned on, or are on dial-up, you can always download updates seperately at: http://windowsupdate.microsoft.com.
Update Non-Microsoft Programs

It is also a good idea to check for the latest versions of commonly installed applications that are regularly patched to fix vulnerabilities. You can check these by visiting Secunia Software Inspector and Calendar of Updates.

Additional Security Programs

For a nice list of freeware programmes in all categories, please have a look at this thread with freeware products that are regarded as useful by the users of this forum: Commonly Used Freeware Replacements.
