I absolutely detest asking for help but this one has me stumped.

I've been given a PC to clean following a "You have a virus, click here to get a virus" incident.

Unfortunately, the user has attempted to clean the problem themselves before handing the machine over. I've no idea what they've done to rectify but everything I've tried (based on the forum's Prep Guide here) has, so far, failed.

Using the numbering in the guide;

1. Full backup has been taken - unsure whether any infection has passed to the backup drive

2. The issue is malware - the PC isn't slow in any way, it just refuses to run any AV

3. Account created

4. Topic reply enabled

5. Vista firewall is active

6. DeFogger has been used to deactivate CD emulation

Here's where the issues arise.

7. DDS has been downloaded and run but nothing happens. The DOS window appears for a nano-second and then vanishes. The only trace of it having run is that it appears to leave a process (SetPath.dat) running. I've left it for an hour and nothing has happened.

8. GMER has also been downloaded and run, but this causes the PC to blue screen as soon as the scan appears to near what I presume is the infected area.

9. I'm afraid I cannot attach any logs as per the details above.

HiJackThis, Malwarebytes, Avast, etc all perform in a similar manner. I can run the installation program and the program, but the second I attempt to scan the file system/HDD of the machine, the GUI vanishes completely. The result is the same whether I'm in Safe Mode or not.

I await the expert opinion on what to do next.

Thank you

/ ode

edit: the OS is 32bit Windows Vista HP SP1

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

Please take note:

  • If you have since resolved the original problem you were having, we would appreciate you letting us 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 we will guide you.
  • Please tell us if you have your original Windows CD/DVD available.
  • If you are unable to perform the steps we have recommended please try one more time and if unsuccessful alert us of such and we 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 another staff member will review your topic an do their 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.

We 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 if you no longer have it available. 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


We 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


Thanks and again sorry for the delay.

Casey

Many thanks for your reply, but I have since sought assistance elsewhere.

Nothing personal ;)

It appears that this issue is resolved, therefore I am closing the topic. If that is not the case and you need or wish to continue with this topic, please send me or any Moderator a Personal Message (PM) that you would like this topic re-opened.
