Can't Remover Rootkit.Agent Virus

By adencklau
May 7, 2010
  1. Hello,
    About a month ago my husband was playing on the internet on my laptop while I was at work. When I got home, he told me that a window popped up on the computer that said I had a virus and that it needed to be remove. He clicked the OK button:( When I scanned the system it came back with a rootkit.agent virus and I can not get rid of it. I have run Malwarebytes and it says that the files will be deleted upon reboot but when I reboot, the same 2 files pull up in the scan as being infected. Can you please help me remove it.

    Please download ComboFix from Here or Here to your Desktop.

    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
    1. Please, never rename Combofix unless instructed.
    2. Close any open browsers.
    3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
      • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
      • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
      NOTE1. If Combofix asks you to install Recovery Console, please allow it.
      NOTE 2. If Combofix asks you to update the program, always do so.
      • Close any open browsers.
      • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
      • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
      • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
    4. Double click on combofix.exe & follow the prompts.
    5. When finished, it will produce a report for you.
    6. Please post the "C:\ComboFix.txt" along with a new HijackThis log for further review.
    **Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

    Make sure, you re-enable your security programs, when you're done with Combofix.

    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!

    Download HijackThis:
    by clicking on Installer under Version 2.0.4
    Install, and run it.
    Post HijackTHis log.
    Do NOT attempt to fix anything!

    NOTE. If you're using Vista, or 7, right click on HijackThis, and click Run as Administrator

    1. Please open Notepad
    • Click Start , then Run
    • Type notepad .exe in the Run Box.

    3. Save the above as CFScript.txt

    4. Then drag the CFScript.txt into ComboFix.exe as depicted in the animation below. This will start ComboFix again.

    Thank you for all your help! Everything seems to be running OK. Should I leave all of the programs that I downloaded during this process or are there any programs that I should uninstall?

    Nice to hear good news :)
    Keep Malwarebytes and run occasional scans.
    Keep TFC and run it weekly.
    All others can go.

    Good luck and stay safe :)
