Long story short I was infected with a trojan that affected the MBR and in the process of removing it in safe mode normal Windows 7 boot isn't possible. As of now when I start up windows it goes to a black screen with a moveable mouse but ctrl alt delete does nothing.

note: I am able to boot to safe mode just fine.

heres the code from catchme.exe

C:\SDFix>Catchme.exe
detected NTDLL code modification:
ZwEnumerateKey 0 != 47, ZwQueryKey 0 != 19, ZwOpenKey 0 != 15, ZwClose 0 != 12,
ZwEnumerateValueKey 0 != 16, ZwQueryValueKey 0 != 20, ZwOpenFile 0 != 48, ZwQuer
yDirectoryFile 0 != 50, ZwQuerySystemInformation 0 != 51Initialization error

Hi adalex,


:welcome: to Bleeping Computer.

My name is Jason and I'll be helping you with your computer problems. You can call me by my screename jntkwx or Jason is fine.

Some things to remember while we are working together.

  • Do not run any other tool untill instructed to do so!
  • Please do not attach logs or put logs in code boxes (unless explicitly asked to)
  • Tell me about any problems that have occurred during the fix.
  • Tell me of any other symptoms you may be having as these can also help.
  • Do not run anything while running a fix.
  • If you don't understand a step, please ask for clarification before continuing with any future steps.

Click on the Watch Topic button and select Immediate Notification and click on proceed, this will help you to get notified faster when I have replied and make the cleaning process faster.

 

Please take note:

  • If you have since resolved the original problem you were having, I would appreciate you letting me know.
  • If you are unable to create a log because your computer cannot start up successfully please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and I will guide you.
  • Please tell me if you have your original Windows CD/DVD available.
  • If you are unable to perform the steps I have recommended please try one more time and if unsuccessful alert us of such and I will design an alternate means of obtaining the necessary information.
  • If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • Upon completing the steps below, I will review your topic and do my best to resolve your issues.
  • If you have already posted a DDS log, please do so again, as your situation may have changed.
  • Use the 'Add Reply' and add the new log to this thread.

I need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links.. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


I also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice

Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


Regards,
Jason
