Hello:

I am running Windows XP SP3 and Internet Explorer 7. I do my Google searches using the box on the upper right hand side of the window. When I click on ANY of my search results, my browers is hijacked and redirected to any number of bogus sites. I can go directly to the address bar to go to any website -- but linking from the search results -- I get hijacked!

I have run RKILL and Malwarebytes software and I have a clean bill of health.

My most recent attempt to clean this up -- I ran HijackThis from Trend -- and the log results are attached. Would anyone be willing to review my HijackThis log file to see if I have any malevolent processes running? I don't want to "fix" anything without some expert advice.

Thank you in advance for your advice.

Regards,

DJAYR

Hello DjayR

Welcome to BleepingComputer smile.gif
==========================
  • Download OTL to your desktop.
  • Double click OTL to run it.
  • When the window appears, underneath Output at the top change it to Minimal Output.
  • Under the Standard Registry box change it to All.
  • Under Custom scan's and fixes section paste in the below in bold

    netsvcs
    %SYSTEMDRIVE%\*.*
    %systemroot%\system32\*.dll /lockedfiles
    %systemroot%\Tasks\*.job /lockedfiles
    %systemroot%\System32\config\*.sav
    %systemroot%\system32\drivers\*.sys /90

  • Check the boxes beside LOP Check and Purity Check.
  • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
    • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post it with your next reply.
====================
Download the following GMER Rootkit Scanner from Here
  • Download the randomly named EXE file to your Desktop. Remember what its name is since it is randomly named.
  • Double click on the new random named exe file you downloaded and run it. If prompted about the Security Warning and Unknown Publisher go ahead and click on Run
  • It may take a minute to load and become available.
  • If it gives you a warning about rootkit activity and asks if you want to run a full scan...click on NO, then use the following settings for a more complete scan..
  • In the right panel, you will see several boxes that have been checked. Ensure the following are UNCHECKED
  • IAT/EAT
  • Drives/Partition other than Systemdrive (typically only C:\ should be checked)
  • Show All (don't miss this one)
  • Then click the Scan button & wait for it to finish.
  • Once done click on the [Save..] button, and in the File name area, type in "ark.txt" or it will save as a .log file which cannot be uploaded to your post.
  • Save it where you can easily find it, such as your desktop
  • **Caution** Rootkit scans often produce false positives. Do NOT take any action on any "<--- ROOKIT" entries
  • Click OK and quit the GMER program.
  • Note: On Firefox you need to go to Tools/Options/Main then under the Downloads section, click on Always ask me where to save files so that you can choose the name and where to save to, in this case your Desktop.
  • Post that log in your next reply.

One or more of the identified infections is a backdoor trojan or rootkit.

This type of infection has the capabilities to allows hacker 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 Identity 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.

If you decide to clean the system then do the following.

=======
Download TDSSKiller and save it to your Desktop.
  • Right click on the file and choose extract all extract the file to your desktop then run it.
  • If prompted to restart the computer type in Y then it will restart.
  • Or if you are prompted with a hidden service warning do go ahead and delete it.
  • Once completed it will create a log in your C:\ drive
  • Please post the contents of that log
========

Download ComboFix from one of these locations:

Link 1
Link 2


* IMPORTANT !!! Save ComboFix.exe 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

  • 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.

  • 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.

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


Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.

Please do not pm for help, post it in the forums instead.

Thank you for the update, of course I am very disturbed by this report.

I did clean the computer. The only problem I had was that I could not turn off the real-time virus protection, that requires a password that only my IT guy knows. . .

Log files are attached.

I will change passwords as you suggest, I will probably upgrade the OS within a few weeks.

The computer seems to be working, the browser is no longer hijacked.

I will be making a donation to bleeping computer, you are a god-send -- thanks for everything.

Regards,

DJAYR

Good morning:

Clean bill of health from Malwarebytes, log attached.

I am running ESET next, but it is possible I won't be able to complete until Monday due to vacation . . . so I may have to attach later.

Abundantly grateful,

Hello:

I finally got to run ESET, which was the next step of this process, and I had a co-worker complete the process because I had to leave early:

1. She reported that 5 infected files were found, and that they were quarantined and then deleted.

2. When I got in this morning to find and attach the log file located at C:\Program Files\ESET\ESET Online Scanner\log.txt -- there was no such directory, file, or folder!

So I don't really know what the program did exactly -- should I run it again, or is there an alternative location of this log.txt file as pertains to ESET?

Just let me know, I do appreciate your help very much.

DJAYR
