    Today I started to get pop ups from Internet Explorer despite using Firefox for browsing, the typical pop ups include Pkr Poker and free iPhones and they are around 5/10 minutes apart. I scanned the system with Ad-Aware and it found a trojan named "Trojan.Win32.Def" which was successfully cleaned, or so it said. I also followed the Malware Removal Guide but the pop ups continued.

    My logs are attatched, however, I was unable to scan with RootRepeal due to an error.

    Thanks very much to the examiner(s) of my logs.

    Hi there and welcome. I am currently reviewing your logs and will get back to you with a set of instructions in the next post I make to you.

    You are running two anti virus which is not a good idea at all! I see both avast 5 and Microsoft Security Essentials, you must now decide which one you wish to keep and ditch the other before we continue.

    Try using the Adblocker plus extension, see if that solves the pop ups. Now, there's a bit of malware to remove, but apart from this I am seeing nothing else that needs doing.

    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::
    
    File::
    c:\users\Liam\AppData\Local\Vxaxewadageqew.dat
    c:\users\Liam\AppData\Local\Syetapaximibah.bin
    c:\users\Liam\AppData\Roaming\wzmjhy.dat
    Registry::
    [-HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{5C255C8A-E604-49b4-9D64-90988571CECB}]
    
    • 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.


    Also delete all files in the below bold folders except ones from the current date (Windows will not let you delete the files from the current day).

    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.

    Thanks, after some research I decided to uninstall Avast and keep MSE. I also had Adblock Plus installed already, but I do think that the pop ups may have stopped, I'll just wait and see.

    Logs are attached below. Thanks!

    You didn't follow step 6 of the R&R. Disabling disk emulation software. Please refer back to step 6 and then:

    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.

    Sorry, didn't realise. Also the pop ups are continuing but they seem to be every 30-45 minutes now.

    MGLogs.zip attached, thank you very much.

    Please close this topic. Thank you for your help Kestrel but I was forced to reinstall windows due to Windows hanging at "Starting Windows" and I was unable to fix it.
