Posted 17 October 2008 - 01:09 PM

Avast has just popped up a warning that I have the following Win32:Agent-QNI[Trj] which it said was located in C:\WINDOWS\system32\dllcache\figaro.sys. I chose to delete it and immediately my laptop shut down and rebooted itself. As soon as it was rebooted I got the following popup from my taskbar telling me: "Your computer is infected! Windows has detected spyware infection!"

I also had a popup from Outpost Firewall letting me know that BRASTK.EXE was trying to make a connection and I created a rule to never allow it to make a connection.

Below is my HijackThis log:

This is my work laptop and I'm in desperate need to get it cleaned up A.S.A.P.

Any help/guidance would be greatly appreciated.

Hello -Maverick-.

Good to see you again, though, but with a not so good infection.

Posted ImageBackdoor Threat
I'm sorry to say that your computer is infected with one or more backdoor trojans.

This means that sensitive information could have been stolen. I would advise to change any passwords for any accounts that you have accessed with the infected computer using a clean computer ASAP. If you have used this computer for banking, I would strongly suggest that you report the possible stolen information. Please do not use the computer for any further transactions, or to enter any other information, if at all possible, until it is declared clean.

You may want to read this article on how to handle identity theft.
You may also want to read this article regarding preventing of identity theft.

This computer can still be cleaned, however, I cannot guarantee that it will be 100% safe even after disinfection.

Please read When Should I Format, How Should I Reinstall.

I will proceed assuming you wish to disinfect. If you want to do a reinstall, reply back saying so.


Install ERUNT
This tool will create a complete backup of your registry. After every reboot, a new backup is created to ensure we have a safety net after each step. Do not delete these backups until we are finished.
  • Please download erunt-setup.exe to your desktop.
  • Double click erunt-setup.exe. Follow the prompts and allow ERUNT to be installed with the settings at default. If you do not want a Desktop icon, feel free to uncheck that. When asked if you want to create an ERUNT entry in the startup folder, answer Yes. You can delete the installation file after use.
  • Erunt will open when the installation is finished. Check all items to be backed up in the default location and click OK.
You can find a complete guide to using the program here:
http://www.larshederer.homepage.t-online.de/erunt/erunt.txt

When we are finished with fixing your computer (I will make it clear when we are), you can uninstall ERUNT through Add/Remove Programs. The backups will be stored at C:\WINDOWS\erdnt, and will not be deleted when ERUNT is uninstalled.

How to Restore from the ERUNT Backup
Only restore from the backups if instructed to, or you need to do so. You need it if after doing something, your computer will only boot in Safe Mode and you are unable to contact us (or anyone else) for help by other means, or if your computer will not boot into Windows at all.

To restore when booted, navigate to C:\WINDOWS\erdnt (possibly WINNT), choose the folder with the most recent date, and double click ERDNT.EXE. Check all boxes in the restoration options.

To restore from the Recovery Console using the Windows CD:
  • Turn on your machine with the disk in the drive.
  • Type in the number of the Windows installation you want to repair (usually 1), then press Enter.
  • Type in the Administrator password (leave blank if you are unsure what it is or if you do not have one) and press Enter.
  • Type without quotes "cd erdnt" followed by Enter.
  • Type without quotes "dir" followed by Enter. This will list out the available folders, whose names are the date on which the backup was taken in (M)M-DD-YYYY format. Try the most recent dates first.
  • Type without quotes "cd **name of the folder**" followed by Enter.
  • Type without quotes "batch erdnt.con" followed by Enter.
  • Type without quotes "exit" followed by Enter.
  • Remove your CD from the drive and reboot your computer into the restored registry. If you still cannot boot, try again with an earlier restore date.

Disable Realtime Protection
Antimalware programs can interfere with the tools we need to run.

Disable Avast!'s realtime protection by right clicking on the try icon beside your clock that looks like Posted Image and selecting Stop On-Access Protection.

In the settings:

Install Recovery Console and Run ComboFix
Download Combofix from any of the links below, and save it to your desktop.
Link 1, Link 2, Link 3

Go to Microsoft's website => http://support.microsoft.com/kb/310994

Select the download that's appropriate for your Operating System.
Posted Image
  • Close/disable all anti-virus and anti-malware programs so they do not interfere with the running of ComboFix. Refer to this page if you are not sure how.
  • Download the file and save it as it's originally named onto your desktop.
  • Drag the setup package onto ComboFix.exe and drop it.
    Posted Image
  • Follow the prompts to start ComboFix and when prompted, agree to the End-User License Agreement to install the Microsoft Recovery Console.
  • At the next prompt, click NO to skip the scan for now.
Posted Image
  • Close everything and save all work.
  • Click on your Start Menu, then Run.., then type:
    "%userprofile%\desktop\combofix.exe" /killall
  • When finished, it will produce a report for you. Please post the contents of the log (C:\ComboFix.txt).
Leave your computer alone while ComboFix is running.

ComboFix will restart your computer if malware is found; allow it to do so.


Download and Run OTViewIt
  • Please download OTViewIt by OldTimer to your desktop.
  • Double click on the OTViewIt.exe icon on your desktop. If you are using Windows Vista, right click the icon and select Run as Administrator.
  • Check both the Scan All Users and Use Whitelist checkboxes. Set the File Age to 30 days.
  • Click on the Run Scan button. Two reports that are located in the same location as OTViewIt will open.OTViewIt.txt <-- Will be opened
    Extra.txt <-- Will be minimized. A new Extra.txt will not be created if one exists already.
Copy and Paste the logs into your next reply.

Post back with:
-the ComboFix log
-the OTViewIt logs

With Regards,
The Panda

Have a good day! :thumbsup:
