Hi,

We are creating a new restore point as well.  We aren't actually getting rid of them all.  :)
----------

I am familiar with Smithfraud.exe but the other is being labeled as having many threats.  We should probably remove this.  When you get the logs attach them to your next reply.

Here attached:
 - mbam log of yesterday
 - otl log after fix (04032012_221855.txt)
 - otl log after quick scan (OTL-120403-2233.Txt)

Sidenote: I have noticed, since a couple of days, that often programs stalls (Firefox, OTL,...) and every time I boot my computer I get an error about Windows Defender "impossible to load application 0x800106ba [...]". And I got also some BSOD.

Hi,

Let's take a look at that error message.  Can you let me know exactly what it says.  If you want you can take a screenshot of it when you see it and attach it here.

Sorry it's in Italian...


It says something like: "impossibile to load/start application: 0x800106ba. The service used by the program have been closed because of a problem. To start the service, reboot the computer or search into the Guide and technical support to find out how to manually start the service."

I have tried opening it through the link in Start menu but I get the same error.

----
P.S. The redirect malware is still there :(

Hi,

Please download Farbar Service Scanner and run it on the computer with the issue.
  • Make sure the following options are checked:
    • Internet Services
    • Windows Firewall
    • System Restore
    • Security Center
    • Windows Update
    • Windows Defender
    • Press "Scan".
    • It will create a log (FSS.txt) in the same directory the tool is run.
    • Please attach the log to your reply.
    ----------

    In the run box type the following

    diskmgmt.msc

    When disc management opens expand it so that all drives are visible
    Take a screenshot and post it here

    Are you able to burn a CD on another computer ?

      Yes

      I'm getting another problem with an Avast warning. As I started Firefox today I got notification of the following malware:
      [/list]
      Code: [Select]
      URL: hxxp:// never labatles.com /cat/v3/main.php...
      Processo: file://C:\Windows\system32\svchost.exe
      Infezione: al

      I have now 10 warnings with the same url...  :'(

      What I should do?
      Thanks

      Hi,

      I need you to download:
      gparted-live-0.10.0-3.iso (115.1 MB) 

      Create a bootable CD, for Gparted from the ISO image.

      You can use ImgBurn do this.

      Now boot off of the newly created Gparted CD. 



      You should be here... Press ENTER



      By default, "do not touch keymap" is highlighted.
      Leave this setting alone and just press ENTER. 



      Choose your language and press ENTER. English is default [33]



      Once again, at this prompt, press ENTER 
      You will now be taken to the main GUI screen below



      According to your logs, the partition that you want to delete is 2mb

      Click the trash can icon to delete and then click Apply.

      You should now be here confirming your actions: 

       

      Now you should be here:

       



      Is "boot" next to your OS drive? 
      If "boot" is not next to your OS drive under "Flags", right-mouse click the OS drive while in Gparted and select Manage Flags 

      In the menu that pops up, place a checkmark in boot like the picture below:

       


      Now double-click the button. 

      You should receive a small pop up like this:



      Choose reboot and then press OK.
      ----------

      Please attempt to run aswMBR again and if a log is created please attach it to your next reply.  :)

      Hi, the redirect thing seems ok (fingers crossed).

      In aswMBR log I have found one Malware and a couple of LOCKED (that F:\ partition seems the one I have deleted). How to fix these?
      I also still have the Windows Defender error posted before.

      Thanks for your help!

      Hi,

      I think that your best option is to uninstall Chrome and just get a fresh install.  That should clear that up and just have a fresh good version on your system.  Remove Google Chrome first by going to Start >> Control Panel >> Programs and Features and then delete Google Chrome.  You can download the new version from here >> https://www.google.com/chrome

      The other entries seen in aswMBR are actually ok.

      OK I have also found how to re-enable Windows Defender. I hope everything is ok now...

      Thank you jeffce for your time and your help!

      Providing there are no more malware related problems...

      IT APPEARS THAT YOUR LOGS ARE NOW CLEAN :D  SO LETS DO A COUPLE OF THINGS TO WRAP THIS UP!! :D

      This infection appears to have been cleaned, but I can not give you any absolute guarantees.  As a precaution, I would go ahead and change all of your passwords as this is especially important after an infection.
      ----------

      The following will implement some cleanup procedures as well as reset System Restore points:

      Click Start > Run  and copy/paste the following text into the Run box as shown and click OK.
        Combofix /Uninstall
        (Note: There is a space between the ..X and the /U that needs to be there.)


      ----------

      Clean up with OTL:
      • Right-click and Run as Administrator OTL.exe to start the program.
      • Close all other programs apart from OTL as this step will require a reboot
      • On the OTL main screen, press the CLEANUP button
      • Say Yes to the prompt and then allow the program to reboot your computer.
      ----------

      Any of the logs that you created for use in the forums or remaining tools that have not yet been removed can be deleted using right-click > delete so they aren't cluttering up your desktop.

      Here are some tips to reduce the potential for spyware infection in the future:

      1. 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.
      2. Enable Protected Mode in Internet Explorer.  This helps Windows Vista users stay more protected from attack by running Internet Explorer with restricted privileges as well as reducing the ability to write, alter or destroy data on your system or install malicious code.  To make sure this is running follow these steps:
      • Open Internet Explorer
      • Click on Tools > Internet Options
      • Press Security tab
      • Select Internet zone then place check next to Enable Protected Mode if not already done
      • Do the same for Local Intranet, Trusted Sites and Restricted Sites and then press Apply
      • Restart Internet Explorer and in the bottom right corner of your screen you will see Protected Mode: On showing you it is enabled.
      3. Use and update an anti-virus software - I can not overemphasize the need for you to use and update your anti-virus application on a regular basis.  With the ever increasing number of new variants of malware arriving on the scene daily, you become very susceptible to an attack without updated protection.

      4. Firewall
      Using a third-party firewall will allow you to give/deny access for applications that want to go online. 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.  A tutorial on firewalls can be found here.  **There are firewalls listed in this tutorial that could be downloaded and used but I would personally only recommend using one of the following two below:
      Online Armor Free
      Agnitum Outpost Firewall Free

      5. Make sure you keep your Windows OS currentWindows XP users can visit Windows update   regularly to download and install any critical updates and service packs. Windows Vista/7 users can open the Start menu > All Programs > Windows Update > Check for Updates (in left hand task pane) to update these systems.  Without these you are leaving the back door open.

      6. Consider a custom hosts file such as MVPS HOSTS. This custom hosts file effectively blocks a wide range of unwanted ads, banners, 3rd party Cookies, 3rd party page counters, web bugs, and many hijackers.  For information on how to download and install, please read this tutorial by WinHelp2002
      Note: Be sure to follow the instructions to disable the DNS Client service before installing a custom hosts file.

      7. WOT (Web of Trust) As "Googling" is such an integral part of internet life, this free browser add on warns you about risky websites that try to scam visitors, deliver malware or send spam. It is especially helpful when browsing or searching in unfamiliar territory. WOT's color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites.  WOT has an add-on available for Firefox, Internet Explorer as well as Google Chrome.

      8.Finally, I strongly recommend that you read TonyKlein's good advice So how did I get infected in the first place?
