    I was asked by a friend to fix an Acer laptop that has a nasty virus which will not allow windows Vista to boot into normal mode or run any antivirus programs in any safe mode. It also disabled system restore and internet access. The only way I could scan it is by booting up using UBCD4WIN and then scanning with its utilities. Avast was able to find some trojans and remove some of them but it skipped most if them. I still can't run any antivirus scans or run an online scan. I tried to follow your READ & RUN ME FIRST. The only way I could get combofix and MG to run is by booting up into basic mode with MSconfig. I attached the files. I am off to work now.

    Please help.:confused

    What do you mean by "basic mode"?

    Are you booting from the hard disk or using UBCD4Win? You need to boot from the hard disk to properly clean it at some point. UBCD4Win is an alternate start point when you cannot get started at all but it will not allow you to remove all aspects of an infection since many parts only show when the hard disk and user account that is infected are booted.

    ComboFix removed a ton of malware. Have you tried running other scans now that ComboFix has been run? If not, please do so and report back. Also download the current version of ComboFix.exe to your Desktop and this time do not rename it.

    Your MGtools logs are incomplete. Did you didable UAC and reboot before running it? Did you notice any error messages or problems? Was any protection software running (like Norton)?



    Now download The Avenger by Swandog46, and save it to your Desktop.
    • Extract avenger.exe from the Zip file and save it to your desktop
    • Run avenger.exe by double-clicking on it.
    • Do not change any check box options!!
    • Copy everything in the Quote box below, and paste it into the Input script here: part of the window:
    • Now click the Execute button.
    • Click Yes to the prompt to confirm you want to execute.
    • Click Yes to the Reboot now? question that will appear when Avenger finishes running.
    • Your PC should reboot, if not, reboot it yourself.
    • A log file from Avenger will be produced at C:\avenger.txt and it will popup for you to view when you login after reboot.
    Now from hopefully normal boot mode, continue with the below or use safe mode if really necessary.

    Run Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

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


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

    Hi chaslang,

    Thank you for the reply. By basic mode I meant "Daignostic startup" my brain just went into neutral. Since my e-mail, I have been able to start in normal boot mode but other problems have developed. The system now does not recognize any mouse or the Synaptics touch pad. Luckily I remembered how to navigate using the keyboard... which is very slow. I tried to re-install the driver but it did not help.

    I also get an error at startup:
    Error loading:c:\Windows\system32\rulufutu.dll

    Here are the files requested.

    When running 'Getlogs.bat' I got the following error many times;
    c:\Windows\System32\cmd.exe
    System\CurrentControlSet\Control\VirtualDeviceDrivers. Virtual Device Driver format in the registry in invalid. Choose close to terminate the application.

    Thanks again.

    Some more info.


    Initially, I used UBCD4WIN just to do the first round of disinfections...there was many. After that I was able to go into safe mode or diagnostic startup.

    I will try ComboFix again as suggested without renaming.

    I verified that the UAC was off before the scan. I also verified that all of the antivirus was off but Combofix came up with a warning.

    Combofix has detected the following real time scanners to be active:
    antivirus: Norton Internet security
    antispyware: Norton Internet Security.

    I tried to find Norton and disable it but it is not listed in the start menu or in the control panel installed programs. I only found windows defender enabled so I turned it off.

    It then got an error from ComboFix with the following info;
    Date Error:2009-11-15
    Check your settings

    When I hit ok, Combofix shuts down.

    I tried to rename it again and re-run. It gave me the same errors about Norton but then it ran.

    I will upload the log when it is finished.

    Thanks,
    Freeka

    Here is the log from the new Combofix scan. I also attached an old log from Malware Bytes from a scan that I did before my first post.

    I tried installing Kaspersky a few times but it would not install properly. I also did a Panda online scan and I think it found 5 infections that it fixed but I can't find the log for it. The system froze after it finished doing the scan.

    I will try to re-load Kaspersky. Either Internet security 2010 download or Antivirus 2009 from my installation CD.

    Thanks,

    Did you ever look at Error Message Type 2 of the instructions given here: Using MGtools

    Note: Per the read and run me instructions, you should only be doing what we as you to do and nothing else. For example, you should not be doing anything with Kaspersky or any other software unless we have asked you to do so.

    According to information in your registry, Norton Internet Security was never uninstalled. At least not properly. This is another reason why Kaspersky should not have been installed.

    Please run the below then reboot. After reboot run it one more time.

    Norton Removal Tool (SymNRT)


    Make sure that you now run MSconfig and select Normal Startup mode before continuing.

    Are the below folders thing you created? Are they needed. If not then delete them.
    Code:
    2009-11-14 13:59 . 2009-11-14 14:28 -------- d-----w- C:\123124871
    2009-11-14 11:37 . 2009-11-14 11:37 -------- d-----w- C:\TMRBLog
    2009-11-14 11:37 . 2009-11-14 11:37 -------- d-----w- C:\log
    2009-11-13 01:17 . 2009-11-13 01:46 -------- d-----w- C:\12330791
    2009-11-13 01:07 . 2009-11-13 01:07 -------- d-----w- C:\123
    

    Uninstall the below old versions of software:
    Java(TM) 6 Update 13
    Java(TM) 6 Update 7

    Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, 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:

    O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)
    O4 - HKLM\..\Run: [MSConfig] "C:\Windows\System32\msconfig.exe" /auto
    O4 - HKLM\..\Run: [vabarajiru] Rundll32.exe "C:\Windows\system32\rulufutu.dll",s
    O9 - Extra button: &Virtual keyboard - {4248FE82-7FCB-46AC-B270-339F08212110} - (no file)
    O9 - Extra button: URLs c&heck - {CCF151D8-D089-449F-A5A4-D9909053F20F} - (no file)
    O9 - Extra button: PartyPoker.net - {F4430FE8-2638-42e5-B849-800749B94EED} - C:\Programs\PartyGaming.Net\PartyPokerNet\RunPF.exe (file missing)
    O9 - Extra 'Tools' menuitem: PartyPoker.net - {F4430FE8-2638-42e5-B849-800749B94EED} - C:\Programs\PartyGaming.Net\PartyPokerNet\RunPF.exe (file missing)

    After clicking Fix, exit HJT.

    Now we need to use ComboFix to remove a bunch of malware files.
    • Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
      • If it is not on your Desktop, the below will not work.
    • Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
    • If ComboFix tells you it has expired or need to be updated to a new version, make sure you allow it to update.
    • Open Notepad and copy/paste the text in the below quote box into it:
    • Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
    • At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
    • You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
    • Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    • Follow the prompts.
    • When it finishes, a log will be produced named c:\combofix.txt
    • I will ask for this log below
    Note:

    Do not mouseclick combofix's window while it is running. That may cause it to stall.


    After reboot, now install the current version of Sun Java from: Sun Java Runtime Environment

    Now run Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

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

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