Redirecting Problem, 8 Steps Completed

By Eulie
Jun 29, 2010
  1. It looks like I'm one of many that have caught the redirecting problem. AVG Free 9.0 detected a trojan a few days ago and put it in the vault and then Spybot S&D alerted me to attempted registry changes by "Lrudozahuyur" and "Chejepuxek", which I blacklisted. I started getting bombarded with notices of the changes being blocked so I ran Malwarebytes, which detected and deleted problems. The registry change attempts stopped. However, I'm still getting a ton of redirects, and AVG, Spybot, Ad-aware, and Malwarebytes all come up clean.

    So I've come to you guys for help. I did the 8 steps. GMER crashed my computer twice so I ended up running it in safe mode.

    Thank you,

    Eulie

    Please download ComboFix from Here or Here to your Desktop.

    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
    1. Please, never rename Combofix unless instructed.
    2. Close any open browsers.
    3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
      • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
      • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
      NOTE1. If Combofix asks you to install Recovery Console, please allow it.
      NOTE 2. If Combofix asks you to update the program, always do so.
      • Close any open browsers.
      • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
      • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
      • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
    4. Double click on combofix.exe & follow the prompts.
    5. When finished, it will produce a report for you.
    6. Please post the "C:\ComboFix.txt"
    **Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

    Make sure, you re-enable your security programs, when you're done with Combofix.

    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!

    About 15mins ago Combofix detected rootkit activity and rebooted my computer. Since then my screen has been black except for the scan window and my mouse cursor is very sluggish. Is it still scanning or should I reboot or something?

    Give it another 15 minutes.
    If no change, restart manually and try again.

    I ended up having to reboot and start again. The second scan went much more smoothly. Strange thing though, after the scan I had IE reinstalled and set as my primary browser.

    How is redirection issue?

    1. Please open Notepad
    • Click Start , then Run
    • Type notepad .exe in the Run Box.

    2. Now copy/paste the entire content of the codebox below into the Notepad window:

    Code:
    File::
    C:\ugrdqpow.sys
    c:\users\Allison\AppData\Local\Ggacinohaz.dat
    c:\users\Allison\AppData\Local\Brexoxicak.bin
    

    3. Save the above as CFScript.txt

    4. Then drag the CFScript.txt into ComboFix.exe as depicted in the animation below. This will start ComboFix again.

    5. After reboot, (in case it asks to reboot), please post the following reports/logs into your next reply:
    • Combofix.txt

    I haven't experienced the redirection issue since starting this process, but I also haven't been using my infected computer for idle surfing.

    I've attached the new ComboFix log. Do you prefer attachments or would you rather I copy and paste the logs into my posts?

    Either way is fine :)

    Delete your GMER file, download fresh one and post new log.

    GMER didn't crash my computer this time!

    Edit: I'm going to have to head off to bed, but I'll be back tomorrow to continue with your next instructions. Thank you so much for taking the time to help me!

    Edit2: When I booted up my computer this morning, two things. a) It started up like a dream! So fast! b) Spybot detected a huge pile of changes, mostly "value deleted". I ended up just disabling Spybot for now because I don't know if those changes are related to what we're doing here or not and I don't want to mess things up.

    Very good :)
    Until we're done with cleaning process, disregard any Spybot complains.

    Uninstall Combofix:
    Go Start > Run [Vista users, go Start>"Start search"]
    Type in:
    Combofix /Uninstall
    Note the space between the "Combofix" and the "/Uninstall"
    Click OK (Vista users - press Enter).
    Restart computer.

    OTL Clean-Up

    * Close all other programs apart from OTL as this step will require a reboot
    * On the OTL main screen, press the CLEANUP button
    * Say Yes to the prompt and then allow the program to reboot your computer.

    If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.

    Ah thank you so much Broni!

    My computer is running brilliantly now. It's way faster on start up and I haven't had any problems with redirection at all. All I have left to do is run a defrag, which I'll be doing tonight as I'm going out.

    Really, thank you for taking the time to help me out like this. I really appreciate it.
