    One of the machines on my father-in-law's farm won't connect to the Internet. Even when I try to ping the gateway the requests time out 2-3 out of four times. :(

    I would appreciate any help you can give us. The logs are attached.

    Thanks,

    Not sure it the connection issues are due to malware or not but there are a few things to clean up. So let's fix these and see what happens. However first before continuing. I want you to uninstall AVG to avoid having it get in the way of proper cleanup. Make sure you uninstall it now before you do the below.

    Uninstall the below very old versions of software:
    J2SE Runtime Environment 5.0 Update 6
    Java(TM) 6 Update 2
    Java(TM) 6 Update 3
    Java(TM) 6 Update 5

    Do you still have anything from Symantec installed? If not then also uninstall the below:
    LiveUpdate 1.80 (Symantec Corporation)


    Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista or Win 7, 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:

    R3 - URLSearchHook: Yahoo! Toolbar - {EF99BD32-C1FB-11D2-892F-0090271D4F88} - (no file)
    O2 - BHO: (no name) - {27B485FE-90CE-4D3B-8BCF-141D4B775D34} - C:\WINNT\system32\mljgf.dll (file missing)
    O2 - BHO: {1d7040e6-5a57-d248-36d4-a3b3218aa2e3} - {3e2aa812-3b3a-4d63-842d-75a56e0407d1} - C:\WINNT\system32\ulrhesvq.dll (file missing)
    O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)
    O2 - BHO: (no name) - {B3ADDB7B-3DF5-4672-82DD-775FFF180134} - C:\WINNT\system32\cbxuuts.dll (file missing)
    O20 - Winlogon Notify: cbxuuts - cbxuuts.dll (file missing)

    After clicking Fix, exit HJT.


    Please download OTM by Old Timer and save it to your Desktop.
    • Right-click OTM.exe and select Run as administrator to run it.
    • Copy the lines from the below codebox to the clipboard by highlighting ALL of them and pressing CTRL + C
      (or, after highlighting, right-click and choose Copy): Do not include the word Code: which is just a title line of
      the code box
    Code:
    :Processes
    explorer.exe
     
    :Files
    C:\WINNT\system32\baksm.dat
    C:\WINNT\system32\cbxuuts.dll
    C:\WINNT\system32\ulrhesvq.dll
    C:\WINNT\system32\mljgf.dll
    echo,Y|cacls "%WinDir%\system32\drivers\etc\hosts" /G everyone:f /c
    ipconfig /flushdns /c
    :Reg
    [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{27B485FE-90CE-4D3B-8BCF-141D4B775D34}]
    [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{1d7040e6-5a57-d248-36d4-a3b3218aa2e3}]
    [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{7E853D72-626A-48EC-A868-BA8D5E23E045}]
    [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{B3ADDB7B-3DF5-4672-82DD-775FFF180134}]
    :Commands
    [purity]
    [EmptyTemp]
    [start explorer]
    [Reboot]
    
    
    • Return to OTM, right click in the Paste List of Files/Folders to Move window (under the yellow bar
      ) and choose Paste.
    • Now click the large [​IMG] button.
    • If OTM asks to reboot your computer, allow it to do so. The report should appear in Notepad after the reboot.
    • Close OTM.
    Now navigate to the C:\_OTM\MovedFiles folder ( assuming your Windows drive is C). This is where your log will be
    saved in the form of Date and Time mmddyyyy_hhmmss.log. Just look for the most recent .log file. Attach
    this log file to your next message.


    After reboot, now install the current version of Sun Java from: Sun Java Runtime Environment

    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:
    • the C:\_OTM\MovedFiles log
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    Sorry about the delay in responding - the Internet connection went down at the farm last week. Hopefully someone from the ISP will be out to troubleshoot it tomorrow morning.

    Unfortunately we had to come home today. If the connection gets fixed tomorrow then I'll ask my brother-in-law to run these instructions. I'll post an update if we are able to make any progress.

    Thanks,

    hcoons
