Hello,

I hope that I am posting in the appropriate thread, please move if necessary. Sometimes pictures speak louder than words so here is a screen shot of the desktop.

Posted Image

I started getting the 'Access Denied' box which leads me to believe that the administrative rights have been corrupted. I have no access to User Accounts, System Restore, or the C Drive. Oh! And I cannot open task manager. I do have access to cmd.

I logged in as Administrator in Safe Mode, and the only task that I was able to complete was to disable some services.

I ran Dial-A-Fix from my thumb drive, and it could not repair the permissions.

Dial-a-fix also displayed 2 Restrictive policies which it could not delete:
1. HKEY_CURRENT_USER\Software\MS\Windows\Currentversion\Policies\System\NoDispBackgroundPage (value=1; Type=REG_DWORD)
2. HKEY_LOCAL_MACHINE\Software\MS\Windows\Currentversion\Policies\System\NoDispBackgroundPage (value=1; Type=REG_DWORD)

Comedian encounters an error then closes. TFC, and ATF Cleaner seemed to run okay but none of the others run at all.

Can I slave the hard drive of the infected PC to my laptop and run the malware removal programs that way, or will it just infect my laptop by doing that?

Hope that helps! Thanks again.

Hello krit86lr

Welcome to G2Go. :)

I would not slave that drive yet.

See if you can do the following at all.
If not in Normal Mode then try Safe Mode.

=====================
Please RIGHT-CLICK HERE and Save As (in IE it's "Save Target As", in FF it's "Save Link As") to download Silent Runners.
  • Save it to the desktop.
  • Run Silent Runner's by doubleclicking the "Silent Runners" icon on your desktop.
  • You will receive a prompt:
    • Do you want to skip supplementary searches?
      click NO
  • If you receive an error just click OK and double-click it to run it again - sometimes it won't run as it's supposed to the first time but will in subsequent runs.
  • You will see a text file appear on the desktop - it's not done, let it run (it won't appear to be doing anything!)
  • Once you receive the prompt All Done!, open the text file on the desktop, copy that entire log, and paste it here.
*NOTE* If you receive any warning message about scripts, please choose to allow the script to run.

I tried running Silent Runners in Safe, and Normal mode but never received the initial prompt. It's been 15 minutes and still nothing seems to be happening. The same thing happened with Combo-Fix.

I'm not sure if this is helpful, but I was able to access MsConfig and noticed some odd programs running at startup:
lich.exe
AlfaCleaner.exe
WinBlueSoft
winstall.exe
spyware doctor (not sure if this is safe or not)

Thanks Again!

I just had a break through! I changed the HijackThis.exe file to HijackThis.scr and it ran and produced a logfile. I am working on the other program now. The 'O20 - AppInit_DLLs: blocker.dll' seems to be a chunk of the problem. Be back in a bit.

That only shows me a small portion of what I need to see.
See if you can rename the following to kahdah.scr

Download ComboFix from one of these locations:

Link 1
Link 2
Link 3


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


  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools

  • 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.

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

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.
