    All,

    First, thank you in advance for your assistance.

    Second, I am trying to fix my dad's computer remotely via LogMeIn. I'm not sure if this will show up as something odd in the logs. Also, some steps may be challenging and will take extra time.

    So on to the problem.

    1) My dad had a serious malware issue. Whatever was on his system was doing the usual blocking of his anti-virus and re-routing. However, I am also sure there were multiple infestations.

    2) I logged in and tried a few different scans (MBAM, Spybot, etc). Found several baddies including "whitesmoke" and a few rootkits. I managed to get his system to allow windows updates again, but still had issues. Of note, google search results, when clicked, would redirect to entirely other sites.

    3) I uninstalled all anti-malware on his system, and turned off windows system restore. I then ran CCleaner, Revo Uninstall, Norton removal tool, AVG removal tool. Basically I made sure I was starting from scratch. Strangely, windows security still though that anti-virus was functional even though there was nothing on the system.

    4) I then started working through your Malware Removal Guide, first doing all the cleanup steps. I even installed all available windows updates and update his java to most recent version.

    5) I then ran the (5) suggested scans in order. The only challenge was ComboFix. It kept freezing right after it show "combofix is preparing to run" even after giving it several hours. So I have attached only 4 of 5 require logs.

    6) It now appears that the system is running OK. The second time I ran MBAM (as part of the 5 steps) it grabbed over 600 items. Also, after doing these scans, windows now realizes that no anti-virus is installed and is correctly warning me.

    7) Before I turn system restore back on and start the process of reprotecting my dad's pc, I want to see if all the baddies are really gone.

    Again, my sincere thanks.

    -- Matthew

    Welcome to Major Geeks!

    Bad idea! You should never do this until malware has been removed. If you mess up during the malware cleaning, a restore point is your fall back even if infected. Now you have no fall back. See our cleaning process and you will see that we do not have you disable System Restore until malware has been verified to be gone.



    Download TDSSKiller from Kaspersky to your directly onto your Desktop
    • Now double click the TDSSkiller.exe file to run it ( if using Vista or Windows 7 do not double click on it but rather, right click and select Run As Administrartor. )
    • If TDSSKiller does not run, try renaming it. To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123tdk.com).
    • Allow the application to run if prompted by Windows or any security programs you have installed
    • It will start the scan and run rather quickly and will notify you of whether anything is found or not.
    • Follow the instructions to delete/quarantine if asks you what to do when if finds something.
    • Whether an infection is found or not, a log file should be created on your C: drive ( or whatever drive you boot from) in the root folder named something like TDSSKiller.2.1.1_27.12.2009_14.17.04_log.txt which is based on the program version # and date and time run. Please attach this log to your next reply. (See: HOW TO: Attach Items To Your Post )

    Ah! I see you already ran TDSSkiller and it found and fixed your TDL infection. You don't need to run it again. Just do the below.


    Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista or Win 7, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:

    O3 - Toolbar: (no name) - {BA52B914-B692-46c4-B683-905236F6F655} - (no file)
    O3 - Toolbar: (no name) - {8EAB99C9-F9EC-4b64-A4BA-D9BCAE8779C2} - (no file)
    O20 - Winlogon Notify: gonrrkt - gonrrkt.dll (file missing)

    After clicking Fix, exit HJT.

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Win7, don't double click, use right click and select Run As Administrator).

    Then attach the below logs:
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    chaslang,

    Thank you for such a fast response.

    1) I turned system restore back on and created a new restore point.

    2) I saw your second post, so I only ran the MGTools\analyse. The log is attached.

    3) His computer *seems* OK. It is hard to tell through LogMeIn, but I think it is running faster than before. I have tried both IE and Chrome in both his profile and mine, and there do not appear to be any redirects. Do the logs look clean?

    4) If so, there are now a lot of new log/txt files in his root directory. What, if any, should I delete?

    Regards,
    Matthew

    Yes but that deleted all previous restore points which could


    Yes. You just need to get it properly protected now which the below will cover.

    Final instructions will automatically take care of most of it.




    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
    2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /uninstall
        • Notes: The space between the combofix" and the /uninstall, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
    3. Go back to step 6 oof the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    6. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    7. Go to add/remove programs and uninstall HijackThis.
    8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
      related to MGtools and some other items from our cleaning procedures.
    9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures pointed to by step 7 of the READ ME
        for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    10. After doing the above, you should work thru the below link:

    chaslang,

    I'll start working through the clean-up steps now. Yes, I understand your point about system restore, and I'll be sure not to do that again next time (and with my dad, there will be a next time).

    I'll report back one last time after all the steps are done.
