Can not run MBAM ... dies after a few seconds

Hi! I've got a laptop here that suffered from the 2010 antivirus bug. I've attempted to install the newest version of MBAM. After updating and running a quick scan, it disappears. Subsequent attempts to run results in:

"Windows cannot access the specified device, path or file. you may not have the appropriate permissions to access the item"

I've attempted to install hijackthis and collect the log but i get the same exact errors.

after reading a few threads, i didn't want to run any other scans without further instructions. I just ran the Eset online virus scan, and it eliminated a few 2010 antivirus bugs, but still have the same issues where i can't run MBAM

Thanks!

Hello HornFan02

Welcome to Malwarebytes.

=====================

  • Download OTL to your desktop.
  • Double click on OTL to run it.
  • When the window appears, underneath Output at the top change it to Minimal Output.
  • Under the Standard Registry box change it to All.
  • Under Custom scan's and fixes section paste in the below in bold


    netsvcs

    %SYSTEMDRIVE%\*.*

    %systemroot%\system32\*.dll /lockedfiles

    %systemroot%\Tasks\*.job /lockedfiles

    %systemroot%\System32\config\*.sav

    %systemroot%\system32\drivers\*.sys /90

    %systemroot%\system32\Spool\prtprocs\w32x86\*.dll


  • Check the boxes beside LOP Check and Purity Check.
  • Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
    • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
    • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post it with your next reply.

====================

Please download Rootkit Unhooker and save it to your desktop.

  • Double-click RKUnhookerLE.exe to run it.
  • Click the Report tab, then click Scan
  • Check Drivers, Stealth Code, Files, and Code Hooks
  • Uncheck the rest, then click OK
  • When prompted to Select Disks for Scan, make sure C:\ is checked and click OK
  • Wait till the scanner has finished then go File > Save Report
  • Save the report somewhere you can find it, typically your desktop. Click Close
  • Copy the entire contents of the report and paste it in your next reply.

Note - You may get this warning it is ok, just ignore it."Rootkit Unhooker has detected a parasite inside itself!

It is recommended to remove parasite, okay?"

ok, OTL doesn't work. It dies mid-scan (never outputs the reports), then becomes inaccessible, and the icon disappears.

One or more of the identified infections is a backdoor trojan or rootkit.

This type of infection has the capabilities to allows hacker to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identity Theft, Internet Fraud and CC Fraud?

When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.

If you still want to clean it please do the following

===================

  • Download TDSSKiller and save it to your Desktop.
  • Extract its contents to your desktop.
  • Once extracted, open the TDSSKiller folder and doubleclick on TDSSKiller.exe to run the application, then on Start Scan.
  • If an infected file is detected, the default action will be Cure, click on Continue.
  • If a suspicious file is detected, the default action will be Skip, click on Continue.
  • It may ask you to reboot the computer to complete the process. Click on Reboot Now.
  • If no reboot is required, click on Report. A log file should appear. Please copy and paste the contents of that file here.
  • If a reboot is required, the report can also be found in your root directory, (usually C:\ folder) in the form of "TDSSKiller.[Version]_[Date]_[Time]_log.txt". Please copy and paste the contents of that file here.

Download ComboFix from one of these locations:

  • Double click on ComboFix.exe & follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
