Infected Again with Malware

By thefranchise808
Jul 9, 2008
  1. Hello, It's been about a month since BlindDragon helped me clean my infected computer. Well unfortunately it looks like it is infected again with the same symptoms. Crazy Internet Explorer, disabled automatic updates and false popups.
    Here is a Superanti spyware log and a hijack this log.
    Help again would be greatly appreciated.

    Thank you very much.

    Is this the same computer - my goodness - If I had to guess it is your browsing habits or maybe even one particular site that you visit with internet explorer - this is because a lot of the infections were in temp folders and IE cache. You should be using Firefox or Opera for normal browsing as they are considered more secure browsers - also did you install spyware blaster - if not we need to put it on there

    You also need to clean out temp files again, but first lets get the rest of the vundo off there.

    I should have listened to you the first time when you told me to use Firefox instead of IE. WIll definitely do so in the future.

    I've followed your instructions and here are the 2 logs:

    Please note I know you directed me to not use Bearshare anymore since the last clean up and I haven't. I guess there are just left over files in my E: that are infected.

    Thanks.

    You may also want to consider keeping malwarebytes - it is free to use/update/scan for as long as you want - I would run it weekly or bi-weekly. It doesn't use any resources when you aren't scanning with it either - so all you lose is the little bit of hard drive space for it.

    I will leave it up to you to delete these:
    File:
    E:\BSINSTALL.exe

    Folder:
    E:\BearShare


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

    Let me see one more hijackthis to double check

    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.

    • 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

      • Next, go to Start > Run and type in cleanmgr

    Things seem to be running smoothly once again.
    2 questions.

    Which version of Firefox do you suggest? I don't need anything too fancy...just basic browsing needs.

    What FREE anti-virus do you suggest should be used? I recently downloaded the free version of AVG 8.

    Nooooooo
    I woke up to some more infections still present.
    Please help me one last time before I never use IE again.
    I still have MBAM and ATF cleaner if you need me to use them again.

    Here is HJT and SAS logs.

    Thank you again for your patience.

    You must have allowed something with comodo, cause it seems to be downloading more malware - its definitely back -

    No more playing around

    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

    • 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

        • 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

    What sort of settings should my COMODO and COMODO safe surf be on.

    example, when I right click comodo in my tray, where should these settings be:

    Firewall Security level :
    Block All Mode
    Custom Policy mode
    Safe Mode
    Training Mode
    Disabled

    Defense+Security level:
    Paranoid Mode
    Safe Mode
    Clean PC Mode
    Training Mode
    Disabled

    - any other tips on how to make my Comodo more stable?
