Virus/Trojan Problem.. please help

Nov 6, 2008
  1. Hi Everyone,

    I'm new here..not exactly a tech whiz but know the basics of computers.
    Anyway, my problem is I've downloaded a trojan/spyware. The names I've written down are Backdoor:WinNT/Rustock.E and Trojan:Win32/Vundo gen!C and Trojan:Win32/Vundo gen!R.

    I've noticed that it keeps causing Internet Explorer windows to pop up with ads for spyware and adware removers etc and it also used to make my computer show up with Data Execution Prevention has closed System Performance Analysis Tools..something about protecting my computer? Anyway, I've run a multitude of scans including ESET Smart Security, AVG, AdAware, Windows Defender, XoftSpySE plus I've followed all the steps on the 8-Step Viruses/Spyware/Malware Preliminary Removal Instructions. I'll attach the 3 log files and if anyone out there is able to help me I would be so grateful! Thanks so much :)

    There are lots of helps available with a gurgle search for Vundo.
    The trick for us is to scan with Kaspersky, SuperAntiSpyware and MalwareBytes, or SpySweeper, to remove, then IMMEDIATEly turn off the machine, and come back in SAFE MODE to scan again.
    Too many of the removal software out there do not work... such as Symantec, Norton, MacAfee, and Trend Micro, as the infestations climb back on after removal.

    So if I scan my system with all those programs and then restart in safe mode, (you press F8 on the opening screen is that right?) and then scan again. What do I do then? Do I restart my computer as normal?

    This is going to need to be removed manually

    Disable real time monitoring by AVG, right click it in the system tray and select disable real time monitoring.

    [​IMG]Combofix
    • Download Combofix to your desktop.
    • Double click combofix.exe & follow the prompts.
    • A window will open with a warning.
    • When the scan completes it will open a text window. Please attach that log back here together with a fresh HJT log.
    Caution - do not touch your mouse/keyboard until the scan has completed. The scan will temporarily disable your desktop, and if interrupted may leave your desktop disabled. If this occurs, please reboot to restore the desktop. Combofix is a very powerful tool so please do NOT do anything without instruction

    Combofix will automatically save the log file to C:\combofix.txt

    K, that looks like it got what I was looking at, but we are still going to remove with a script just to be sure.

    Also: Did you remove norton through add/remove programs? Looks like we need to run the norton removal tool from ---> http://service1.symantec.com/Support/tsgeninfo.nsf/docid/2005033108162039

    ===================================================

    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)
    Save this as CFScript.txt

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

    [​IMG]

    This will start ComboFix again. After reboot, (in case it asks to reboot), post the contents of Combofix.txt in your next reply

    ===============================================

    Make sure you followed step 6 about updating your Java and afterwards, uninstall any older versions. You should only have Java 6 update 10


    [​IMG]CCleaner
    • Download from HERE
    • Close all browsers.
    • Run the programme and make sure all the boxes are ticked under the Windows and Applications tabs, Also check All Advanced tabs(except for the Old prefetch Data option, this should be unticked)
    • Click the run cleaner button.

    ===========================================

    [​IMG]Run Kaspersky Online AV Scanner

    In order to use it you have to use Internet Explorer.
    Go to Kaspersky and click the Accept button at the end of the page.

    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 license accepted, reset to 100%.
    • Read the Requirements and limitations before you click Accept.
    • Allow the ActiveX download if necessary.
    • Once the database has downloaded, click Next.
    • Click on "My Computer"
    • When the scan has completed, click Save Report As...
    • Enter a name for the file in the Filename: text box and then click the down arrow to the right of Save as type: and select text file (*.txt)
    • Click Save - by default the file will be saved to your Desktop, but you can change this if you wish.
    Attach the report into your next reply



    I wanna see the combofix log from the script and the kaspersky log

    Hi,

    I've attached the log files as requested. Is my computer free of problems now?
    Just to let you know I have NOD32 ESET Smart Security as my anti-virus and Comodo Firewall as my firewall. Are these programs ok to use?

    Thanks again

    Em :)

    yes NOD32 is a great antivirus and Comodo is a great firewall. I will list below some additional tools that you can use to keep your system secure and notify you of attacks.


    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.update.microsoft.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

    Nobody can give you a 100% guarantee unless you were to format the drive and do a clean install. However, in my opinion you are clean, and that opinion was confirmed by kaspersky's online scanner which is very thorough online scanner. I feel confident that you are safe, but just wanted to point out there is no way for me to be 100%.

    Just keep a close eye on Comodo and what is trying to connect from your machine, if you don't know what a file is feel free to ask, or search for it on google before granting it access.
