    AVG has been buggy for a very long time, refusing to update for months.
    Recently though, performance of computer has gone down so I installed NOD trial and it popped up with multiple things but was unable to do anything.
    Trial run out and it's now been uninstalled. (1 week ago)
    AVG has been re-installed but every time I attempt to update, the installer module crashes. (3 days ago)

    SHeur3.AQRA and Zbot.B are names which pop up from AVG quite often while doing things.

    Firefox has started to crash on open command. I feel as if it's getting worse and worse.

    I believe that I have followed all the guidelines correctly, here attached are the logs.

    Thank you for your time and assistance,
    Xavier.

    Running from: c:\users\Chiya\Desktop\GET CLEAN\ComboFix.exe <--- Take it out of the folder you have combofix in and place it directly onto your desktop.

    Soon we will have you use the AVG Removal Tool to be rid of avg remnants, and install some antivirus, but not yet, let's make some progress first.

    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    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:

    After clicking Fix exit HJT.

    Now we need to use ComboFix
    • 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 needs to update to a new version, make sure you allow it to update.
    • Open Notepad and copy/paste the text in the below quote box. Ensure you scroll down to select ALL the lines:
    Code:
    KILLALL::
    
    SecCenter::
    {17DDD097-36FF-435F-9E1B-52D74245D6BF}
    
    DirLook::
    C:\Users\Chiya\AppData\Local\{5D67A~1
    
    File::
    c:\program files\microsoft\desktoplayer.exe
    C:\Users\Chiya\AppData\Local\itesujoxumuge.dll
    C:\Users\Chiya\AppData\Local\mshlox5.dll
    C:\Users\Chiya\AppData\Local\Dqibazo.bin
    C:\Users\Chiya\AppData\Local\Rqurakuka.dat
    C:\Program Files\Internet Explorer\complete.dat
    C:\Program Files\Internet Explorer\dmlconf.dat
    c:\users\Default\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\ulsi.exe
    
    Folder::
    c:\program files\win
    c:\program files\tmp
    c:\program files\system
    C:\Users\Chiya\AppData\Local\temp\nso455.tmp
    c:\users\Chiya\AppData\Roaming\Qoto
    c:\users\Chiya\AppData\Roaming\Dybyne
    c:\users\Chiya\AppData\Roaming\Taehak
    c:\users\Chiya\AppData\Roaming\Pogaw
    c:\users\Chiya\AppData\Roaming\Ekziin
    c:\users\Chiya\AppData\Roaming\Opxape
    c:\program files\Messenger Plus! Live
    c:\users\Chiya\AppData\Roaming\Fusua
    c:\programdata\Messenger Plus!
    c:\users\Chiya\AppData\Roaming\Efky
    c:\users\Chiya\AppData\Roaming\Kipu
    c:\users\Chiya\AppData\Roaming\Moyc
    c:\users\Chiya\AppData\Roaming\Esupq
    
    Registry::
    [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
    "{A3DF0367-A33E-82F5-5D1B-C2F69BF1B3BA}"=-
    "Pwedogi"=-
    [HKEY_LOCAL_MACHINE\software\microsoft\windows\currentVersion\Run]
    "Lledegohe"=-
    [HKEY_LOCAL_MACHINE\software\microsoft\windows nt\currentversion\winlogon]
    "Userinit"="c:\windows\system32\userinit.exe,"
    
    • 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

      [​IMG]

    • 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.

    Sooner or later you will need to tidy up your desktop:

    There are far too many files scattered about that should be in their own suitable folders in another location on your machine. Having a messy desktop is an ideal way to lose data, and an easy way for malware to hide, also it can have an impact on performance.

    Run this:
    Using ESET's Online Scanner

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this.

    Tell me how the PC is behaving.

    I don't seem to have an "analyse.exe" in the MGtools folder.
    There's a folder called "temp", then 62 files starting with "BamFix.bat"
    Going though to "zia05840"
    Should I re-download?

    analyse.exe is there:

    "C:\MGtools\"
    analyse.exe 23 Apr 2010 388608 "analyse.exe

    Then download it this way if you still cannot see it.
    Trend Micro HijackThis 2.04 Final Then continue on with the rest of my instructions.
