Cannot Run Hijack This or any type of AV scan


Recommended Posts

I had a virus on my Toshiba Satellite Pro Laptop called Katusha

The virus knocked out Norton and the only way I could eventually get rid of it was with the Norton boot-scan disk, so now I do not have a virus but it seems to have left behind some problems.

The main problem at this point is that I cannot run any type of virus scan or Hijack This also anything to do with a network connection is also disabled or does not work properly so I cannot get on the internet or connect with another computer.

I dont know if anyone can help, maybe I need to run hijack this in safe mode I dont really know to be honest what to try but as I said any form of scan that could potentially help to fix the computer gets knocked out.

Operating system is windows vista home premium

Thanks

Gerald

Hi and :welcome:

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

  • 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 explaination 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.

Hello, unfortunately you have a nasty rootkit on your computer. Before starting to clean it, please read the following.

BACKDOOR WARNING

------------------------------

One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would advice 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 infection 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 Identify 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 decide to go through with the cleanup, please proceed with the following steps.

COMBOFIX

---------------

Please download ComboFix from one of these locations:


Bleepingcomputer
ForoSpyware

  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. (Click on this link to see a list of programs that should be disabled. The list is not all inclusive.)
  • Double click on Combofix.exe and 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, or if you are running Vista, ComboFix will continue it's malware removal procedures.

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

RC_successful.gif

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.

Hi thank you for the information.

I am going to go ahead and try and fix it as it is not essential that this computer goes online as I mainly use it for running music software, so presumably if I don't go online after getting rid of the root kit everything else should be OK

I will follow the instructions that you have sent and let you know how I get on

Many thanks

Gerald

Hi Elise I have run combo fix and all seemed well to start with but it seems to have got as far as deleting Folders C:\Windows\$NtUninstallKB20723$ and then got stuck.

It has actually been stuck for about half an hour so what would you recommend?, I am not sure whether to shut down and try again so I will wait for your reply

Cheers

Gerald

Don't worry, most of these files were already in quarantine. :)

ALL CLEAN

--------------

Your machine appears to be clean, please take the time to read below on how to secure the machine and take the necessary steps to keep it clean :)

Please do the following to remove the remaining programs from your PC:

  • Delete the tools used during the disinfection:
    • Click start > run and type combofix /uninstall, press enter. This will remove Combofix from your computer.

Please read these advices, in order to prevent reinfecting your PC:

  1. Install and update the following programs regularly:
    • an outbound firewall. If you are connected to the internet through a router, you are already behind a hardware firewall and as such you do not need an extra software firewall.
      A comprehensive tutorial and a list of possible firewalls can be found here.
    • an AntiVirus Software
      It is imperative that you update your AntiVirus Software on regular basis.If you do not update your AntiVirus Software then it will not be able to catch the latest threats.
    • an Anti-Spyware program
      Malware Byte's Anti Malware is an excellent Anti-Spyware scanner. It's scan times are usually under ten minutes, and has excellent detection and removal rates.
      SUPERAntiSpyware is another good scanner with high detection and removal rates.
      Both programs are free for non commercial home use but provide a resident and do not nag if you purchase the paid versions.
    • Spyware Blaster
      A tutorial for Spywareblaster can be found here. If you wish, the commercial version provides automatic updating.

[*]Keep Windows (and your other Microsoft software) up to date!

I cannot stress how important this is enough. Often holes are found in Internet Explorer or Windows itself that require patching. Sometimes these holes will allow an attacker unrestricted access to your computer.

Therefore, please, visit the Microsoft Update Website and follow the on screen instructions to setup Microsoft Update. Also follow the instructions to update your system. Please REBOOT and repeat this process until there are no more updates to install!!

[*]Keep your other software up to date as well

Software does not need to be made by Microsoft to be insecure. You can use the Secunia Online Software occasionally to help you check for out of date software on yourmachine.

[*]Stay up to date!

The MOST IMPORTANT part of any security setup is keeping the software up to date. Malware writers release new variants every single day. If your software updates don't keep up, then the malware will always be one step ahead. Not a good thing.

Please reply to this topic if you have read the above information. If your computer is working fine, this topic will be closed afterwards.

Hi Elise many thanks for your message all seems to be working well but typing combofix/uninstall does not seem to work I get the message that "Windows cannot find Combofix/uninstall please try again" so I am not sure what to do about that.

Thanks Gerald
