Hi, my pc was infected with this trojan. AVG detected it in resident shield and was removed to virus vault and deleted. However, next start up and scan still show the virus.

Here is my hijackthis log:

Hi 9mubz

To start with please follow the instructions below

DownLoad CCleaner

*NOTE* CCleaner deletes EVERYTHING out of temp/temporary folders. If you have anything in a temp folder,
back it up or move it to a permanent folder prior to running CCleaner!

Download CCleaner to clean temp files from your computer.

http://www.ccleaner.com/download/builds/downloading-slim


Double click on the file to start the installation of the program.
Select your language and click OK, then next.
Read the license agreement and click I Agree.
Click next to use the default install location. Click Install then finish to complete installation.
Double click the CCleaner shortcut on the desktop to start the program.
On the "Windows" tab, under "Internet Explorer," uncheck "Cookies" if you do not want them deleted.
(If deleted, you will likely need to reenter your passwords at all sites where a cookie is used to recognize you when you visit).
If you use either the Firefox or Mozilla browsers, the box to uncheck for "Cookies" is on the Applications tab, under Firefox/Mozilla.
Click on the "Options" icon at the left side of the window, then click on "Advanced."
deselect "Only delete files in Windows Temp folders older than 48 hours."
Caution: It is not recommended that you use the "Issues" feature unless you are very familiar with the registry as it has been known to find legitimate items.
  • Click the "Run Cleaner" button.
  • A pop up box will appear advising this process will permanently delete files from your system.
  • Click "OK"
  • CCleaner will scan and clean your system.
  • When cleaning is complete:
  • Click "Exit".
  • Repeat for all usernames.



Please make sure you run CCleaner on each user account before running the
online scan, this cuts down on scan time and log size.



1 - Kaspersky Online Scan
With the exception of Internet Explorer, which must be used for this scan, keep ALL programs closed
Please do an online scan with >Kaspersky Online Scanner<. You will be prompted to install an ActiveX component from Kaspersky, Click Yes.
Note for Internet Explorer 7 users: If at any time you have trouble with the accept button of the licence, click on the Zoom tool located at the right bottom of the IE window and set the zoom to 75%. Once the licence accepted, reset to 100%.
  • The program will launch and then start to download the latest definition files.
  • Once the scanner is installed and the definitions downloaded, click Next.
  • Now click on Scan Settings
  • In the scan settings make sure that the following are selected:
    o Scan using the following Anti-Virus database:
    + Extended (If available otherwise Standard)
    o Scan Options:
    + Scan Archives
    + Scan Mail Bases
  • Click OK
  • Now under select a target to scan select My Computer
  • The scan will take a while so be patient and let it run.
  • Please do not use your computer while the scan is running. Once the scan is complete it will display if your system has been infected.
  • Click the Save Report As… button

  • In the Save as… prompt, select Desktop
  • In the File name box, name the file KasScan-ddmmyy (or similar)
  • In the Save as type prompt, select Text file (see below)
  • Copy and paste the report in your next post.
Note: It is recommended to disable onboard antivirus program and antispyware programs while performing scans so there are no conflicts and to speed up scan time.
Please don't go surfing while your resident protection is disabled!
Once scan is finished remember to re-enable resident antivirus protection along with whatever antispyware application you use.

Hi 9mubz



One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and Download and Execute files

I would 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 Trojan 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 attempt to clean this machine but i can't guarantee that it will be 100% secure afterwards.

Should you have any questions, please feel free to ask.

Please let us know what you have decided to do in your next post.



If you would like to have a go at cleaning please follow instructions below


  • Please download Flash_Disinfector and save it to your desktop.
  • Double click to run it.
  • You will be prompted to plug in your flash drive. Please make sure you plug all your Flash drives, thumb drives, pen drives, USB drives in.
  • Flash_Disinfector will start disinfecting your flash and hard drives. This takes a few seconds. Your desktop will disappear in the meantime.
  • When done, a message box will appear. Click OK. Your desktop should now appear. If it doesn't, press Ctrl + Shift + Esc to open Task Manager.
  • Click on File > New Task (Run…). Type in explorer.exe and press Enter. Your desktop should now appear.



Please recheck your system with a second online scan, but first please re-run CCleaner, and make sure all your
Flash drives, thumb drives, pen drives, USB drives are still connected.


1 - Kaspersky Online Scan
With the exception of Internet Explorer, which must be used for this scan, keep ALL programs closed
Please do an online scan with >Kaspersky Online Scanner<. You will be prompted to install an ActiveX component from Kaspersky, Click Yes.
Note for Internet Explorer 7 users: If at any time you have trouble with the accept button of the licence, click on the Zoom tool located at the right bottom of the IE window and set the zoom to 75%. Once the licence accepted, reset to 100%.
  • The program will launch and then start to download the latest definition files.
  • Once the scanner is installed and the definitions downloaded, click Next.
  • Now click on Scan Settings
  • In the scan settings make sure that the following are selected:
    o Scan using the following Anti-Virus database:
    + Extended (If available otherwise Standard)
    o Scan Options:
    + Scan Archives
    + Scan Mail Bases
  • Click OK
  • Now under select a target to scan select My Computer
  • The scan will take a while so be patient and let it run.
  • Please do not use your computer while the scan is running. Once the scan is complete it will display if your system has been infected.
  • Click the Save Report As… button

  • In the Save as… prompt, select Desktop
  • In the File name box, name the file KasScan-ddmmyy (or similar)
  • In the Save as type prompt, select Text file (see below)

  • Copy and paste the report in your next post.
Note: It is recommended to disable onboard antivirus program and antispyware programs while performing scans so there are no conflicts and to speed up scan time.
Please don't go surfing while your resident protection is disabled!
Once scan is finished remember to re-enable resident antivirus protection along with whatever antispyware application you use.

Hi DFW, I will reformat my windows. My system (laptop) was bought 2nd hand recently with windows already installed . Whether my computer was infected before that I have no idea. I used system for web surfing, word and photos processing and playing games. Sad to say, I'd also performed a few internet banking since buying 2nd hand and hence my account name and password should be captured by the backdoor Trojan. However, the internet banking have a 2nd factor authentication which I'm holding on by my side, in order to access my internet bank acount. I have a few questions here: 1. What's the exact risk of my security breach given the above? 2. I did not kept my user name or passwords to any banks/ credit cards account on any saved files, documents whatever on my hard disk. So is the backdoor trojan only able to steal my information (i.e. credit card numbers, personal numbers, bank account numbers) through what is being displayed on the webpage that I'm viewing? Thank you.

Hi 9mubz


I would print out these instructions as some instructions are for when Internet is not available


That is a good choice, to reformat your laptop, especially if it was pre used, you don't know what has gone on in the past, or what
infections it has had, this way you will have a fresh clean system.

To answer your questions about the backdoor, at present it is in system restore, but that means that it must of been, at
sometime withing windows and active, the trouble is with this type of infection is that we will never know if it's been cleaned out
100%, or what if any, damage has been done to your system files, and what security loopholes have been opened, so taking this
into account I would reformat and reinstall if it was my system.


We are erring on the side of caution, it better to be safe than sorry.


When a backdoor is active withing windows it can give the writers/black-hatters control over your system, It allows outsiders COMPLETE access to every keystroke,
account, and password you use while on this machine, and complete access to any other data present or stored on your system.

As we do not know when this backdoor was active you should contact your banks, credit card companies, and financial institutions and let them know you MAY have
been a victim of identity theft, and to put a watch on your accounts.

BUT first I would go to a clean system and change all passwords, all INTERNET banks will have a help line, call them if you cannot change
your password online.

Before you reformat do not forget to back up any important data you have, before you copy this data back scan it with a Antivirus and a Antispyware programs,
dont forget contacts and email account details, also do you have the key-codes and copies of all your software to reinstall, if you do not have a
recovery partion, if not then you will also need the key-code and XP disc for windows, are you OK with reformatting or are you going to need help??.


At present you D Drive is infected, DO NOT reinstall windows and connect this drive, it needs to be cleaned or formatted as well , if this drive is your only means
of back up, or it has important data on, then you should try and clean it, with the intructions below, if you plan to reformat it don't worry.



To Clean D Drive

  • Please download Flash_Disinfector and save it to your desktop.
  • Double click to run it.
  • You will be prompted to plug in your flash drive. Please make sure you plug all your Flash drives, thumb drives, pen drives, USB drives in.
  • Flash_Disinfector will start disinfecting your flash and hard drives. This takes a few seconds. Your desktop will disappear in the meantime.
  • When done, a message box will appear. Click OK. Your desktop should now appear. If it doesn't, press Ctrl + Shift + Esc to open Task Manager.
  • Click on File > New Task (Run…). Type in explorer.exe and press Enter. Your desktop should now appear.


Then run a second online scan to make sure D Drive is safe
