Seperate to my other thread, I also have issues with my laptop which is being troubled by the Trojans mentioned in the subject title.

Log files attached.

Appreciation in advance.

then post a fresh log. Also disable and enable system restore

http://support.microsoft.com/kb/264887
 
Those items didn't appear in the Hijack This scan.

Anyway, disabled system restore.

Log attached.

Thanks again.
 
How is your computer running I do not see anything in your log I will double check to make sure
 
It is running ok. It's just AVG keeps coming up with these trojans.

Will see what happens over next few days.

Thanks for your help !
 
Today's scan came up all clear. Hopefully it is ok now. Will post in this thread if any further infections.

Thanks again.

Did you ever run Malwarebytes Anti-malware on this system? It usually picks up zlob

Run CFScript

Open notepad and copy/paste the text in the code box below into it:
NOTE* make sure to only highlight and copy what is inside the quote box nothing out side of it.
Also ..

Pay particular attention to this :-

Make sure the word File:: is on the first line of the text file you save (no blank line above it, & no space in front of it)
File::
C:\WINDOWS\system32\{ba52c3fc-0c5e-77f1-4956-76bc18296ea2}.dll-uninst.exe
C:\WINDOWS\system32\B5V6wcHi.exe.a_a

Save this as CFScript.txt

Then drag the CFScript.txt into ComboFix.exe as you see in the screenshot below.

CFScript.gif


This will start ComboFix again. After reboot, (in case it asks to reboot), attach Combofix.txt

-------------------------------------------------------------------------

Then if you haven't already run MBAM i suggest doing that as well ->
Malwarebytes' Anti-Malware

  • Please download Malwarebytes' Anti-Malware to your desktop.
  • Double-click mbam-setup.exe and follow the prompts to install the program.
  • At the end, be sure a checkmark is placed next to
    • Update Malwarebytes' Anti-Malware
    • and Launch Malwarebytes' Anti-Malware
  • then click Finish.
  • If an update is found, it will download and install the latest version.
  • Once the program has loaded, select Perform full scan, then click Scan.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Be sure that everything is checked, and click Remove Selected.
  • When completed, a log will open in Notepad. please attach this log with your reply
    • If you accidently close it, the log file is saved here and will be named like this:
    • C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\mbam-log-date (time).txt
 
All done abd Logs attached. I may have overlooked that scan initially! Definately did it on my other system which I was trying to sort out at the same time.
 
Good work please post one more hijackthis for me and do the following:

good work -

Uninstall Combofix
* Click START then RUN
* Now type Combofix /u in the runbox
* Make sure there's a space between Combofix and /u
* Then hit Enter.

* The above procedure will:
* Delete the following:
* ComboFix and its associated files and folders.
* Reset the clock settings.
* Hide file extensions, if required.
* Hide System/Hidden files, if required.
* Set a new, clean Restore Point.

-----------------------------------------------------------------------

OTCleanit! by Oldtimer
  • Download OTCleanIt
  • Click the CleanUp! button.
    • It will go thorugh the list and remove all of the tools it finds and then delete itself (requiring a reboot).

---------------------------------------------------------------------------

Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:
  1. Set correct settings for files
    • Click Start > My Computer > Tools menu (at top of page) > Folder Options > View tab.
    • Under "Hidden files and folders" if necessary select Do not show hidden files and folders.
    • If unchecked please check Hide protected operating system files (Recommended)
    • If necessary check "Display content of system folders"
    • If necessary Uncheck Hide file extensions for known file types.
    • Click OK

    clear system restore points

    • This is a good time to clear your existing system restore points and establish a new clean restore point:
      • Go to Start > All Programs > Accessories > System Tools > System Restore
      • Select Create a restore point, and Ok it.
      • Next, go to Start > Run and type in cleanmgr
      • Select the More options tab
      • Choose the option to clean up system restore and OK it.
      This will remove all restore points except the new one you just created.

  2. Make your Internet Explorer more secure - This can be done by following these simple instructions:
    1. From within Internet Explorer click on the Tools menu and then click on Options.
    2. Click once on the Security tab
    3. Click once on the Internet icon so it becomes highlighted.
    4. 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.
    5. Next press the Apply button and then the OK to exit the Internet Properties page.
  3. Use an AntiVirus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

    See this link for a listing of some online & their stand-alone antivirus programs:

    Virus, Spyware, and Malware Protection and Removal Resources

  4. Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

  5. 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 succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

    For a tutorial on Firewalls and a listing of some available ones see the link below:

    Understanding and Using Firewalls

  6. 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.This is done in Vista through control panel -> windows updates.

  7. Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

    A tutorial on installing & using this product can be found here:

    Using SpywareBlaster to protect your computer from Spyware and Malware

  8. Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
Follow this list and your potential for being infected again will reduce dramatically.

here are some additional utilities that will enhance your safety

  • IE/Spyad <= IE/Spyad places over 4000 websites and domains in the IE Restricted list which will severely impair attempts to infect your system. It basically prevents any downloads (Cookies etc) from the sites listed, although you will still be able to connect to the sites.
  • MVPS Hosts file <= The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your coputer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer
  • Google Toolbar <= Get the free google toolbar to help stop pop up windows.
  • Winpatrol <= Download and install the free version of Winpatrol. a tutorial for this product is located here:
    Using Winpatrol to protect your computer from malicious software
 
Done.

Thanks once again for all the help.

Will post again in this thread if any further issues.

Have a good day.
