  1. I have cleaned up this computer so it now connects to the internet. It had much malware. I tried to clean up as much as I could. Could someone please help me with the enclosed scan logs. Thanks.

    You’re about done with this. - -Continue with procedure
    Successive scans are used to uncover additional infections, since masking is common with many infestations. When a tool reports something it can not clean, that's when the strategy calls for a stronger scan program​
    • Update both MBAM & SAS. Rerun them both.

    • This effort is complete when logs report NO infections/threats, or reporting something it can not clean.
      • Typically extra repeat scans are not needed
    • Posts logs. Report progress & what changes are observed. Include logs that found infections.

    The two scans are now clean. I think I see some potential problems on Hijack This but I will wait to hear from you. Thank you so much for your help.

    Adding some specifics helps with performing the analysis. Symptoms and observations add to the technical picture. Having said that 'winrpcmx.exe' is toxic.

    Here is some reading for you: Trojan - online banking credentials

    ComboFix is used for the next scan. ComboFix is a very effective tool that scans / fixes hard to clean infections. Additionally, it includes diagnostic information.
    • Uninstall old copy of ComboFix

    • Follow ComboFix instructions referenced below.

    • Restart the computer.

    • Scan with HJT. (part of instructions for ComboFix)

    • Posts logs. Report progress & what changes are observed.

    I had trouble downloading ComboFix so I ran it from a cd. The two scans are enclosed. Thanks for your help.

    SDBot Trojan extremely dangerous

    I will ask another specialist to assist with removing this infection. You will see me add technical details to this reply to expose more of the infection.

    Please indicate that you understand that this infection threatens your identity, your accounts, and your passwords if this computer is used for online banking and commerce.

    1. This can give intruders complete control of your computer, logging key strokes, stealing information.

    2. You are strongly advised to disconnect infected computer immediately from any networked computers until the computer can be cleaned.

    3. If this computer is used for banking or commercial transactions online, take measures to protect your identity
      • While using the infected computer, Do NOT change passwords or do any transactions because the attacker will get the new passwords and transaction information.

    Script file is not complete.
    [-HKEY_LOCAL_MACHINE\software\microsoft\shared tools\msconfig\startupreg\Lexmark_X79-55]

    Yes. I do understand. Is this problem fixable by hjt?

    HJT is part of the solution. I am studying other cases as I pick through the combofix log. Another specialist will construct the script file and recommend a stronger scan tool.

    Sorry it took so long. The computer seems to be running fine. I had trouble with downloading Norton removal tool and the Kaspersky took several hours to run. The two logs are attached. Thanks.

    That task is done. Here's another hjt log.

    Well, the log looks clean to me :) How's the system running?

    Now would be a good time to install SP3, from Windows Update
  16. marygg

    marygg TS Booster Topic Starter Posts: 121

    I originally started out with a conflict between sp3 and a dlink wireless adapter driver so I uninstalled sp3 to try to install the dlink. I plan to verify the driver works and reinstall sp3. Should I remove superantispyware and malwarebytes? Also hjt and combofix were already on this computer when I started working on it. Should I remove them?

    kimsland Ex-TechSpotter Posts: 14,523

    Yes :)

    And if installing SP3 (good idea ;) ) Probably any other program (personal firewall etc)
