I want to start with the fact that I haven't downloaded the DSS program that you guys recommend. This is because I have disconnected the two windows based computers from the internet so as to avoid further incursions while I am fixing them. I am currently using my mac laptop. I'm working on them one at a time. I have a Dell, that I don't use much anymore since I go to college and so am not near it very much; which I am working on first and so will call PC 1. The other is my younger brother's custom build which was infected first and will be harder to fix, I imagine; I'll call it PC 2.

Sometimes I surprise myself how long winded I can be. Regardless, my mother who is tech savy found out that the problem with PC 2 is a virus of some sort. I don't know the name. She was recommended to get three programs: HiJack This, Super AntiSpyware, and Malwarebytes. We start up the dell to use it to download the programs and it shows symptoms of infection from the same virus. As it turns out, my brother used my dell to finish an essay for school....and apparently some other stuff.

My mother and I then downloaded the three programs on the mac and put them on a thumb drive to be put on the PC's. This rounabout process is why I haven't gotten and used your DSS program. I can if you insist, but I won't be able to copy and paste the logs anyway. Especially since even if I do reconnect the PC's to the internet the virus prevents the use of any browser.

If you tell me the version info and stuff I will find it and post if for each computer. Meanwhile I have already run HJT on PC 1 and have spent the last two hours looking up questionable entries; mostly on links to your forums. So I decided to sign up and ask the experts directly. Can I just post the log entries that I have questions/doubts about and work from there?

In this forum we try to screen infections problem and see if we can solve them here, some will be very nasty and we might reccomend a reinstall, some will be cleanable with easy to use selfhelp tools like those you mentioned first, MBAM and SAS.

If they and a few others don't work we refer you on to the HJT forum where they require a HJT or DDS log.

The HJT forum gets very backedup since the tools and logs produced are so complicated it takes helpers a lot of work to analyze.


If you post a HJT or DDS log here, this thread will be closed and you will have to enter the que waiting for expert help.

If you can wait up to a week or so that's not a bad idea, but start a thread in that forum before posting those logs.

It's your decision but we can look at your MBAM log(s)

Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • 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 updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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 and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. 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 after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Thanks Chewie
I hadn't used the other two programs yet, only HJT. I'm running the MBAM scan now

I'm still having trouble with PC 2. Malwarebytes finds 4 trojan agents all under a name starting with "gaopdx"
C:\WINDOWS\system32\gaopdxcounter
\gaopdxleilpvgk.dll
\gaopdxlmxpmhrk.sys
\gaopdxlpsdixpn.sys

And then when I tell malwarebytes to fix them it freezes. Hijackthis won't even finish it's scan because of something like "the program is running"


Here is the malwarebytes log file:

That's a real nasty rootkit


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

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

Thanks for the help. Fortunately the computer has been disconnected from the internet all week, as far as i know, and isnt used for anything with that kind of sensitive information. I was trying to avoid reformatting as you probably know, but I'll just have to go through with it.

Once again, thanks for all your help

Please download gmer.zip and save to your desktop.
  • Extract (unzip) the file to its own folder such as C:\Gmer. (Click here for information on how to do this if not sure.)
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security program drivers will not conflict with gmer's driver.
  • Click on this link to see a list of programs that should be disabled.
  • Double-click on gmer.exe to start the program.
  • Allow the gmer.sys driver to load if asked.
  • You may be prompted to scan immediately if GMER detects rootkit activity.
  • If you are prompted to scan your system click "Yes" to begin the scan.
  • If not prompted, click the "Rootkit/Malware" tab.
  • On the right-side, all items to be scanned should be checked by default except for "Show All". Leave that box unchecked.
  • Select all drives that are connected to your system to be scanned.
  • Click the Scan button to begin. (Please be patient as it can take some time to complete)
  • When the scan is finished, click Save to save the scan results to your Desktop.
  • Save the file as gmer.log and copy/paste the contents in your next reply.
  • Exit GMER and re-enable all active protection when done.
