    Hello

    Recently my home computer started having issues and i noticed that mywebsearch was installed. I ran Malwarebyes Anti-malware and it detected a lot of issues as well as a rootkit. After it resolved the issues i noticed that my internet connection wasn't working anymore. I've had issues in the past and so i ran Combofix which 98% of the time has fixed any problems i might have. It ran and popped up with a warning that it had found Rootkit.ZeroAccess installed in the tcp/ip stack. It finished running and reported that it had removed more issues but after restart i still have no internet connection. I've run combofix many times as well as malwarebytes since then and even though their reports are now coming back clean i still have no internet connection.

    So here i am looking for help. attached are the logs. If you would like me to try and find earlier logs of malwarebyes or combofix i can search for them. These are the most recent logs.

    Thanks

    Rustin

    http://img805.imageshack.us/img805/9659/rktigzy.gif Use ProxyFix in RogueKiller.

    Double-click RogueKiller.exe to run. (Vista/7 right-click and select Run as Administrator)
    When it opens, press the Fix Proxy button.
    When it is finished, there will be a log on your desktop called: RKreport[2].txt
    Attach RKreport[2].txt to your next message. (How to attach)

    Reboot and test for internet connection.

    If that didn't work, you can try this too:

    http://img205.imageshack.us/img205/4783/regeditb.gif Open Notepad and copy everything in the code box below into it.
    Code:
    REGEDIT4
    
    [HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
    "ProxyServer"=-
    [HKEY_USERS\S-1-5-18\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
    "ProxyServer"=-
    • File -> Save As -> Save as type: "All Files" -> File Name: fixme.reg > Save.
    Now merge this into the registry by double-clicking it.
    Let me know if the merge was successful or not. If successful, reboot and test for internet connection.

    Open the Device Manager

    • Collapse the Network Adapters list.
    • Right mouse click: Intel(R) 82562V 10/100 Network Connection
    • Choose "Uninstall".
    • You be asked to confirm your actions, choose OK and let it uninstall.
    • If it asks you if you want to delete the driver software / files too, say No.
    • When you have done this and Intel(R) 82562V 10/100 Network Connection is no longer in the Device Manager list -- Press the Scan for hardware changes button (http://img803.imageshack.us/img803/2868/scanhardware.png) or Action -> Scan for hardware changes
    • Allow it to reinstall your network adapter.
    • Reboot for changes to occur.
    • Test internet once you have rebooted.

    http://img97.imageshack.us/img97/8120/fss.gif Please download Farbar Service Scanner and run it on the computer with the issue.
    • Make sure all the options are checked
    • Press Scan.
    • It will create a log (FSS.txt) in the same directory the tool was run.
    • Please attach FSS.txt to your next message. (How to attach)

    Ok, it sounds the TCP/IP stack is completely broken.

    Try this next as it should work:

    Click Start, and then click Run.
    In the Open box, type regedit, and then click OK.
    In Registry Editor, locate the following keys, right-click each key, and then click Delete:
    • HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
    • HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2
    When you are prompted to confirm the deletion, click Yes.
    Close the Registry Editor.

    Locate the Nettcpip.inf file in C:\WINDOWS\inf and then open the file in Notepad.
    Locate the [MS_TCPIP.PrimaryInstall] section. Change the Characteristics = 0xA0 entry by replacing 0xA0 with 0x80. Save the file. Exit Notepad.
    In Control Panel, double-click Network Connections, right-click Local Area Connection, and then select Properties.
    On the General tab, click Install, select Protocol, and then click Add.
    In the Select Network Protocols window, click Have Disk.
    In the Copy manufacturer's files from text box, type C:\WINDOWS\inf, and then click OK.
    Select Internet Protocol (TCP/IP), and then click OK. It will report as unsigned, this is the one we want! Do not choose Microsoft TCP/IP v6!

    Note This step returns you to the Local Area Connection Properties screen. However, the Uninstall button is now available.
    Select Internet Protocol (TCP/IP), click Uninstall, and then click Yes.
    You will be asked to reboot your PC for the changes to take affect, go ahead and do this now.

    Once you have rebooted...
    In Control Panel, double-click Network Connections, right-click Local Area Connection, and then select Properties.
    On the General tab, click Install, select Protocol, and then click Add.
    In the Select Network Protocols window, click Have Disk.
    In the Copy Manufacturer's files from text box, type C:\WINDOWS\inf, and then click OK.
    Select Internet Protocol (TCP/IP), and then click OK.
    Restart your computer.
    Test your Internet connectivity.

    Alright i deleted the winsock items in the registry and made the following change

    [MS_TCPIP.PrimaryInstall] section. Change the Characteristics = 0xA0 entry by replacing 0xA0 with 0x80

    Rebooted the computer, reinstalled the network protocol and still no internet.

    Was i supposed to change the Characteristic back to 0xA0?
     
  10. thisisu

    thisisu Malware Consultant

    Did you complete all the steps? Because you are not supposed to reboot right after changing 0xA0 with 0x80.

    We want it to be 0xA0, however, 0x80 works too. Point is to toggle it just so Uninstall button becomes available.

    There may be a conflict with McAfee as well. I recommend uninstalling it through Add/Remove Programs and then download the following from a computer with working internet: MCPR.exe and transferring it to the computer with issues and executing it. It is McAfee's uninstall tool so we remove as many traces of McAfee as possible.

    Very important that this trace from Device Manager is uninstalled as well: McAfee Core NDIS Intermediate Filter Miniport - (Network Adapters)

    Going to bed soon, keep me posted whenever you can.

    Okay so i uninstalled mcafee from the control panel, downloaded MCPr.exe and ran it to further uninstall mcafee. Yet as i opened the device manager to remove the miniport that you had suggested i noticed that Intel(R) 82562v 10/100 Network connection under Network adapters had an x over it. Right clicked it and it said that it was disabled. I was able to enable it and then tested the internet connection and now everything is working!
