zeroaccess infection

    I have had a zeroaccess trojan on my computer since yesterday. I first tried nortons own removal tool but that did not work and since then the virus has disabled access to norton 360 completely. As of this morning I haven't had any access to my windows in normal mode, all I see is the wallpaper and the virus has had my task manager disabled from the get go.

    I have however been able to run norton npe in safe mode, which found one iteration of the virus but didn't remove it completely. I've also followed your instructions apart from two, that I can think of, exceptions.

    #1: I couldn't disable my norton 360 because I've no access to it in normal mode and in safemode seems to prevent the running of the program

    #2: Also I can't uninstall java, I've 6.0 update 26, when I try to uninstall it it says windows installer coulnd't be accessed. I can uninstall other programs

    The required logs should be all attached

    Thanks for the quick reply.

    Ran all the checks, but the problem still persists. Didn't do anything with the roguekiller check results since you only specified a scan.

    Thanks for an other quick reply. Ran both scans, deleted the file and windows booted in normal mode. Taskmanager opens normally. Malwarebytes detected and blocked outbound traffic almost as soon as I started IP-BLOCK (Type: outgoing)

    Also removed java

    Are you having trouble with PS/2 keyboard and mouse?

    Your logs are clean for the most part as I am not seeing any actual malware to remove.

    Both my keyboard and mouse are usb and there's no trouble at my end either.

    Thanks for all the help :)

    No problem.

    Here are a few things I recommend doing before we cleanup.

    [​IMG] Please download Disable/Remove Windows Messenger to your desktop.
    • Double-click MessengerDisable.exe to run it.
    • Place checkmarks in "Uninstall Windows Messenger" and "Hide Messenger from Outlook Express"
    • Click Apply
    • Click Exit

    [​IMG] Now install the current version of Sun Java from: jre-7u3-windows-i586.exe

    As far as the PS/2 keyboard and mouse goes, the service and files required for it are missing. This is most likely due to the rootkit. We could restore them if you wanted to (just incase you ever needed to use PS/2 kb/mouse), I leave this decision up to you.


    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 of 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 if it present
    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 through the below link:
    Be safe :)

    I doubt I'll ever use a PS/2 mouse/kb so installing the drives would be pretty pointless.

    I presume using combofix means when you drag&drop a text file on it? Even though I didn't do that do I still have to uninstall combofix?

    I think that's about it thanks a lot for your help.
