Hello,

It appears that I've been infected with a rootkill and it's been difficult to remove. Attached are logs of DDS and Rootkill Unhooker.

Hi,

Please do the following:

  • Please download aswMBR.exe and save it to your desktop.
  • Double click aswMBR.exe to start the tool. (Vista/Windows 7 users - right click to run as administrator)
  • Click Scan

  • Upon completion of the scan, click Save log and save it to your desktop, and post that log in your next reply for review. Note - do NOT attempt any Fix yet.
  • You will also notice another file created on the desktop named MBR.dat. Right click that file and select Send To>Compressed (zipped) file. Attach that zipped file in your next reply as well.

Please download TDSSKiller.zip
  • Extract it to your desktop
  • Double click TDSSKiller.exe

Hi,

Please do the following:

Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • 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.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Posted Image

  • Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Posted Image

  • Click on Yes, to continue scanning for malware.
When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.

hello,

Ran Combofix but the program crashed and closed just like the aswMBR program. When i tried to run Combofix again, this warning appeared "Windows cannot access the specified device,path or file. You may not have the appropriate permissions to access the item". Also, my computer hasn't been displaying any System Tray icons or desktop shortcuts. My desktop is completely blank with only the picture of my wallpaper displaying.

Please try this:

We need to scan the system with this special tool.

  • Please download Junction.zip and save it to your desktop.
  • Unzip it and put junction.exe in the Windows directory (C:\Windows).
  • Now go to Start > Run to open a run box > Copy and paste the following command in the open run box and click OK:

    cmd /c junction -s c:\ >log.txt&log.txt& del log.txt

  • A command window will open and the system will be scanned.
  • Wait until a log file opens.
  • Copy and paste or attach the content of it in your next reply

OK

Please try the following:

Please delete the copy of ComboFix that you have on your desktop and download a fresh copy, but rename it to yuge.com before saving it, now save it directly to your c:\ drive

(make sure you have extensions visible so you can save it as a .com file)

now boot into safe mode with networking and run it, be sure to allow it to install the Recovery Console, as the way this is going, I believe we are going to need it:

To Show File Extensions
  • Double-click My Computer.
  • Click the Tools menu, and then click Folder Options.
  • Click the View tab.
  • Clear "Hide file extensions for known file types."
  • Click Apply, and then click OK.



To Enter Safemode
  • Go to Start> Shut off your Computer> Restart
  • As the computer starts to boot-up, Tap the F8 KEY repeatedly,
  • this will bring up a menu.
  • Use the Up and Down Arrow Keys to scroll up to Safemode with networking
  • Then press the Enter Key on your Keyboard
  • go into your usual account

Hello,

I can't delete ComboFix. This is the error message i get "Error Deleting File or Folder" : "Cannot delete ComboFix:Access is denied. Make sure the disk is not full or write-protected and that the file is not currently in use."

There's nothing displayed on my desktop so i can't double click the "My computer". The only way i've been navigating around is through Windows Task Manager. I will try to restart my computer now in safe mode with networking (i hope it works because i tried earlier this morning but my computer completely crashed after the "WINDOWS" logo.

I just want to say thanks again for taking the time to assist me =)

Hello,

GrantPerms program has been running for about 10+ minutes now and the "Unlock Operation Started. Please wait..." message is still showing. Is that normal or did it freeze/crash? Also during the run, an error message appeared titled "GrantPerms by Farbar: GrantPerms.exe - Corrupt File: The file or directory C:\Documents and Settings\NetworkService.NT AUTHORITY\Local Settings\Temporary Internet Files\Content.IE5\LX5XVWKV\vod[1].js is corrupt and unreadable. Please run the Chkdsk utility."
