Hi again,

Open notepad and copy/paste the text in the quotebox below into it:

http://www.bleepingcomputer.com/forums/topic216344-15.html

Collect::
c:\windows\system32\sfcfiles.dll


Save this as
CFScript

A word of warning: Neither I nor sUBs are responsible for any damage you may have caused your machine. This tool is not a toy and not for everyday use.

Posted Image

Close all browser windows and refering to the picture above, drag CFScript into ComboFix.exe. You will be asked to submit malware samples. Please follow the given instructions to submit the sample.
Then post the resultant log & a fresh dds.txt log.


Combofix should never take more that 20 minutes including the reboot if malware is detected.
If it does, open Task Manager then Processes tab (press ctrl, alt and del at the same time) and end any processes of findstr, find, sed or swreg, then combofix should continue.
If that happened we want to know, and also what process you had to end.

Hi

Thanks for the sample :thumbup2:

Are you able to boot in normal mode? Looks like both ComboFix and DDS were run in safe mode.

Hi again,

Download & extract this file to it's own folder - Registry Search

Launch Registry Search
In the search box, enter (on separate lines)

OptionValue
SAFEBOOT_OPTION


Under "Search", make sure only the "Value" box is checked in the first row of checkboxes. All other checkboxes should be checked.

& click "Ok".
Notepad will open with some text in it (the file will also be saved in the program's folder as well).
Post this text in your next reply.

Hi

Please follow steps 1-3 behind this link to backup your registry with ERUNT (use current date while naming the location).

Save text below as fix.reg on Notepad (save it as all files (*.*)) on the Desktop.

REGEDIT4

[-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Option]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]
"SAFEBOOT_OPTION"=-

It should look like this -> Posted Image

Doubleclick fix.reg, press Yes and ok.

Reboot and post a fresh dds.txt log.

Hi

Why would you have to remove those programs? Please try IE now so that we can see if it works ok. That's the only way to find out if infection is still lurking somewhere :thumbup2:

You're welcome :)

Well congrats, it appears your system is all clean Are you still noticing any problems? If not, it's time to secure your system to prevent against further intrusions.


THESE STEPS ARE VERY IMPORTANT

Let's reset system restore
Reset and Re-enable your System Restore to remove infected files that have been backed up by Windows. The files in System Restore are protected to prevent any programs changing those files. This is the only way to clean these files: You will lose all previous restore points which are likely to be infected. Please note you need Administrator Access to do clean the restore points.

1. Turn off System Restore.
On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
Check Turn off System Restore.
Click Apply, and then click OK.

2. Reboot.

3. Turn ON System Restore.
On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
UN-Check *Turn off System Restore*.
Click Apply, and then click OK.
NOTE: only do this ONCE,NOT on a regular basis



We need to re hide system files. To do so, please follow the steps below:
  • Double-click My Computer.
  • Click the Tools menu, and then click Folder Options.
  • Click the View tab.
  • Put a check by
    Hide file extensions for known file types.
  • Under the
    Hidden files
    folder, select
    Show hidden files and folders.
  • Check
    Hide protected operating system files.
  • Click Apply, and then click OK.

Now lets uninstall ComboFix:
  • Click START then RUN
  • Now type Combofix /u in the runbox and click OK
Next we remove all used tools.

  • Double-click OTViewIt.exe.
  • Click the CleanUp! button.
  • Select Yes when the
    Begin cleanup Process?
    prompt appears.
  • If you are prompted to Reboot during the cleanup, select Yes.
  • The tool will delete itself once it finishes, if not delete it by yourself.
Note: If you receive a warning from your firewall or other security programs regarding OTViewIt attempting to contact the internet, please allow it to do so.




UPDATING WINDOWS AND INTERNET EXPLORER

IMPORTANT: You Need to Update Windows and Internet Explorer to protect your computer from the malware that is around on the Internet. Please go to the windows update site to get the critical updates.

If you are running Microsoft Office, or any portion thereof, go to the Microsoft's Office Update site and make sure you have at least all the critical updates installed (Free) Microsoft Office Update.


Make your Internet Explorer more secure

This can be done by following these simple instructions:
From within Internet Explorer click on the Tools menu and then click on Options.
Click once on the Security tab
Click once on the Internet icon so it becomes highlighted.
Click once on the Custom Level button.
Change the Download signed ActiveX controls to Prompt
Change the Download unsigned ActiveX controls to Disable
Change the Initialize and script ActiveX controls not marked as safe to Disable
Change the Installation of desktop items to Prompt
Change the Launching programs and files in an IFRAME to Prompt
Change the Navigate sub-frames across different domains to Prompt
When all these settings have been made, click on the OK button.
If it prompts you as to whether or not you want to save the settings, press the Yes button.
Next press the Apply button and then the OK to exit the Internet Properties page.



The following are recommended third party programs that are designed to keep your computer clean. A link as well as a brief description is included with each item.
  • hosts file:
    • Every version of windows has a hosts file as part of them.
    • In a very basic sense, they are used to locate webpages.
    • We can customize a hosts file so that it blocks certain webpages.
    • However, it can slow down certain computers.
    • This is why using a hosts file is optional!!
    Download it here. Make sure you read the instructions on how to install the hosts file. There is a good tutorial here
    If you decide to download the hosts file, the slowdown problems can usually be avoided by following these steps:
    • Click the start button (at the lower left hand corner of your screen)
    • Click run
    • In the dialog box, type services.msc
    • hit enter, then locate dns client
    • Highlight it, then double-click it.
    • On the dropdown box, change the setting from automatic to manual.
    • Click ok
  • Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a Firewall in its default configuration can lower your risk greatly. For more info, check this webpage out.
    If you don't have a 3rd party firewall or a router behind NAT then I recommend getting one. I recommend either Online Armor Free or Comodo Firewall Pro (If you choose Comodo: Uncheck during installation "Install Comodo SafeSurf..", Make Comodo my default search provider" and "Make Comodo Search my homepage" and install firewall ONLY!).

Just a final reminder for you. I am trying to stress these two points.
UPDATE UPDATE UPDATE!!! Make sure you do this about every 1-2 weeks.
Make sure all of your security programs are up to date.
Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.



Once again, please post and tell me how things are going with your system... problems etc.

Have a great day,
Blade :thumbup2:
