    I worked through the malware removal process. At some point after initiating the Combofix utility, I lost my internet connection. I restored to an earlier point and regained the connection. I started the removal process from the beginning and after the MGtools step, I noticed I had once again lost internet connection. I tried manually adding the IP address and a DNS address, but this did not work. All other machines on this home router are working ok.

    I have attached my logs for analysis. I'm a little concerened about the huge (2GB) hyperfil.sys file in my C: drive root folder.:confused

    Welcome to Major Geeks!

    Why is this PC being used with no protection software installed?

    Did you run any scans more than once? We do specifiy to only run scans once and attach the logs. Based on your logs you did start having some issues and ran scans on July 8.


    It is part of Windows and normal.

    You need to attach the below logs from SUPERAntiSpyware and Malwarebytes that were requested. You will have to attach all of them since you ran scans multiple times.
    Code:
    "C:\Documents and Settings\James\Application Data\SUPERAntiSpyware.com\SUPERAntiSpyware\Logs\"
    Jul  8 2010 4209  "SUPERAntiSpyware Scan Log - 07-08-2010 - 06-07-27.log"
    Jul 18 2010 3728  "SUPERAntiSpyware Scan Log - 07-18-2010 - 10-42-05.log"
    Jul 18 2010  465  "SUPERAntiSpyware Scan Log - 07-18-2010 - 11-12-44.log"
                                                                                
    "C:\Documents and Settings\James\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\"
    Jul  8 2010 1711  "mbam-log-2010-07-08 (07-12-52).txt"
    Jul 18 2010 1032  "mbam-log-2010-07-18 (11-40-53).txt"
    

    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 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.

    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 or Win7, 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!


    If you are still having problems, your last logs indicated that a network interface card (NIC) is not being found in this PC. You may need to reinstall drivers. You should also check Device Manager for errors under Network Adaptors.
