Hi everyone !!

I received a alert from Avast telling me that a Rootkit-gen has been found in C:\\WINDOWS\System32\Drivers\nwirxasc.sys, which field I can't delete.
I read on different website to use HijackThis and I make a logfile as advised, but then.. I don't know how to interprete it :flowers:

My informatical knowledges aren't that good, so I was hoping maybe someone could help me with it ?
Thanks a lot !! :thumbsup:

Hello,

As no logs have been posted, I am shifting this topic from the specialized HiJack This forum to the Am I Infected forum.

Rootkits are bad business and require tools limited to the HiJack This forum to take care of. Please follow the instructions in ==>This Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<==

If you cannot produce the DDS logs, then post back here and we will provide you with further instructions.

IMPORTANT NOTE: HijackThis is an advanced enumerator (similar in some respects to a registry editor) that is used to display certain areas of the Windows registry where the majority of malware reside. HijackThis will scan these areas of your system and then create a log to help diagnose the presence of undetected malware in known hiding places. However, since HijackThis only scans certain areas of your system/registry, a log may not always show all the malware on your system and other investigative tools need to be used. Most of the log entries are required to run a computer and removing essential ones can potentially cause serious damage such as loss of Internet connectivity or problems with your operating system which could preventing it from starting. Using HijackThis requires advanced knowledge about the Windows Operating System and relies on trained experts to interpret the log entries and investigate them in order to determine what needs to be fixed.

And just because you "fixed" something with HijackThis, that does not mean you have a clean system. There are specific files and folders which must be deleted afterwards. HijackThis does not delete them. Futher, removing entries in HijackThis before the problem is properly identified can make the malware undetectable to other detection and removal tools. Full system scanning tools like SUPERAntispywre, Malwarebytes' Anti-Malware, Spybot S&D and SpySweeper will remove the registry entries as well as the related files which results in a more complete removal process. HijackThis this should only be used to clean up the entries left behind, after you have properly removed the malware.

Since HijackThis is a powerful tool that requires advanced knowledge about the Operating System and can cause system damage if incorrect instructions are given, only designated trained experts are allowed to help people with using HijackThis. If you do not have advanced knowledge about computers or training in the use of this tool, you should NOT fix anything using HijackThis without consulting a expert as to what to fix.

With that said, there are tutorials available for advanced users which will help you understand more clearly about the use of HijackThis and what it does.Please download Malwarebytes Anti-Malware (v1.44) and save it to your desktop.alternate download link 1

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

-- If Malwarebytes Anti-Malware results in any error messages, check the Help file's list of error codes within its program folder first. If you do not find any information, please refer to Common Issues, Questions, and their Solutions, Frequently Asked Questions. If the error you are receiving is not in the list, please report it here so the research team can investigate.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/287387/infected-with-rootkit-genrtk/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days, up to two weeks perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
