TL;DR
Java rootkit is bootline and invisible to AVG, superantispyware, malwarebytes, and spybot-SD, revoked my user control rights to nearly every system file and promoted 'Trusted Installer' instead. Logs attached.


I was browsing the web and picked up a flash based rootkit. The flash installer warning came up asking yes/no and then came up many times at once, I tried to ctrl-alt-del and was already locked out. I hard powered off the system, detatched the non OS drives and attached the OS drive to another pc for infection removal. AVG, spybot and Malwarebytes report nothing wrong with the file system, yet when I boot from the drive I am clearly infected with a browser hijacker. It disabled my firewall and turned off security services, which I simply reenabled after running Rkill, which allowed me to see all my administrative user rights to almost every file on the pc have been removed from "Administrator" to "Trusted Installer". I have run Superantispyware as well and found nothing with it. As a temporary measure I applied ownership of iexplorer.exe back to administrator and changed the filename to prevent it from opening until I can completely clean it. I removed all other browsers and installed chrome to a removable drive for diagnostic purposes and downloading antivirals directly. Now it too is suffering from hijacks and redirects when using any search options. When running gmer the error "loaddriver ('C:\Users\Justin\AppData\Local\Temp\pxlyqpow.sys') error 0xc000010E An instanceo f the service is already running" popped up, and most of the checkmarks are greyed out. Not sure if thats due to system configuration or infection.


Process of events;
Infection through flash(firefox), unable to open task manager/start button
Hard power off
Removal of drive and scan with AVG Free on clean PC
No infections found, drive returned to original pc, on boot user account spawning copies of regedit.exe, trusted installer.exe, iexplorer.exe, dllhost.exe
Ran Rkill, regained control of administrative functions
Ran HijackThis
Overnight scans of AVG, Superantispyware, Malwarebytes, Spybot SD, nothing but cookies found.
Ran TFC from OldTimerTools, cleaned out temp files
renamed iexplorer to obscene backup name in frustration
Rebooted, Ran Gmer and fresh hijackthis, attached logs to this post


If I'm lucky the sharks will stay away until I reach shallow water.

Attached File  hijackthis-2.txt   6.6KB   2 downloads
Gmer attachment is too large to post(3mb), will throw it up mediafire.

Hello and welcome to Bleeping Computer!

I am HelpBot: an automated program designed to help the Bleeping Computer Staff better assist you! This message contains very important information, so please read through all of it before doing anything.

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.

To help Bleeping Computer better assist you please perform the following steps:

***************************************************

If you no longer need help, then all you needed to do was the previous instructions of telling me so. You can skip the rest of this post. If you do need help please continue with Step 2 below.

***************************************************

Posted Image If you still need help, I would like you to post a Reply to this topic (click the "Add Reply" button in the lower right hand of this page). In that reply, please include the following information:

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • A new DDS and GMER log. For your convenience, you will find the instructions for generating these logs repeated at the bottom of this post.
    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log 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.
  • Upon completing the above steps and posting a reply, another staff member will review your topic and do their best to resolve your issues.

Thank you for your patience, and again sorry for the delay.

***************************************************

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


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!
