Zlob.dnschanger possibly removed after 8 steps

  1. I have followed all the 8 steps aprat from a couple of exceptions.

    i kept getting an error when trying to update my Java so have not been able to do that.

    I was also unable to update Malwarebytes Anti Malware but after doing a full system scan in safe mode i could open the program once again and update (although i have not run another scan yet).

    I believe i may have eradicated the problem but seeing as i went through all 8 steps i thought i might as well make sure everything has been removed. Below are my logs.

    When as badly infested as these logs show second runs are required to get the others that were exposed by the first runs.

    So UPDATE both MBAM and SAS and run again, attache the logs but look at them and if there were cleaned entries then run again. We are looking for a clean log!

    Ok i have scanned my system again with updated Anti-Malware and Super Anti Spyware and also Spybot.

    Below are the log files again, to be honest they do not seem much different from the previous ones.

    Oh No these are different. Your first logs were bad, you were worse off than you think. Hopefully this will finish up.

    These are items found on first run and not finished cleaning and some that were not seen at all by the first run.

    UPDATE MBAM and SAS but do not run

    OK do the below...

    Boot to Safe Mode With Networking. During this post at any required reboot always boot back to Safe Mode Networking.

    Left Drag mouse and Copy for Pasting all text in the box below. Make sure the slider bar goes to bottom from the @ to the end of the second exit.

    Then paste to the black screen of an open command prompt. All may not apply so ignore errors.

    If a reboot is incurred or required then boot back to Safe Mode Networking.

    Still in Safe Mode networking now run MBAM and SAS quick scans, attach logs.

    Finally

    Download ComboFix

    NOTE: If you have had ComboFix more than a few days old delete and re-download.

    Get it here: http://download.bleepingcomputer.com/sUBs/ComboFix.exe
    Or here: http://subs.geekstogo.com/ComboFix.exe

    Double click combofix.exe follow the prompts.

    When finished, it will open a log.
    Attach the log and a new HJT log in your next reply.

    Note: Do not click combofix's window while its running. That may cause it to stall.

    Now back to normal mode.

    I have just completed all of the above.

    The only problem i came across was when running combo fix in safe mode it told me to deactivate my Avira antivirus software. As far as i could tell it wasnt running due to being in safe mode (i checked task manager but could not see any processes relating to Avira).

    Other than that everything processed fine.

    Below are the logs.

    Ok MBAM had 1 found entry UPDATE and run another Quick scan! We need a clean log!
    --------------------------------------------------------------------------------------------------------
    Download SD Fix to Desktop

    http://downloads.andymanchesta.com/RemovalTools/SDFix.exe

    On Desktop run SDdFix It will run (install) then close.

    Then reboot into Safe Mode

    As the computer starts up, tap the F8 key several times.

    On the Boot menu Choose Safe Mode.

    Click thu all the prompts to get to desktop.

    ComboFix found and had removals.So at this point run Combofix again.

    Then....

    At Desktop
    My Computer C: drive. Double-click to open.

    Look for a folder called SD Fix. Double-click to enter SD Fix.

    Double-click to RunThis.bat. Type Y to begin.

    SD Fix does its job.

    When prompted hit the enter key to restart the computer

    Your computer will reboot.

    On normal restart the Fixtool will run again and complete the removal process then say Finished,
    Hit the Enter key to end the script and load your desktop icons.

    Once the desktop is up, the SDFix report will open on screen and also be saved to the SDFix folder as Report.txt.
    Attach the Report.txt file to your next post.

    Hopefully this will do it!

    Fantoostical!

    I think you did it. Great job!

    1st. Run full UPDATED Avira scan post log

    2nd. Run SDFix once more to confirm the Trojan files it found are actually gone now, attach log!

    Then final HJT scan attach log.

    Get me a status of how system is working now and any remaining issues.

    Done everything you said.

    My computer seems to be running better and it feels like the internet is loading faster.

    Below are the logs requsted.

    ALLRIGHT! Thats what I'm talking about!

    You are Clean.

    Thread closing-------------------------------------------------------------------------------------

    Start-Run
    type
    Combofix /u
    click ok or hit enter

    Next

    Please download OTCleanIt http://download.bleepingcomputer.com/oldtimer/OTCleanIt.exe

    Save to desktop.

    This will remove all the tools we used to clean your computer.
    These tools update so often they require downloading again later if needed.

    Double-click OTCleanIt.exe. Click CleanUp. Yes to the "Begin cleanup Process?"

    Approve all if prompted by Firewall, Widows Defender or other guards or security programs about OTCleanIt attempting access to the Internet, allow all.

    If prompted to Reboot click Yes.
    OTCleanit will delete itself when finished, if not delete it by yourself.

    -------------------------------------------------------------------------------------
    Run CCleaner again twice or more on Cleanup temps, then on left click Registry then Scan for issues also repeat till clean.

    D/L install and run ATF-Cleaner clear all except passwords in all browsers you have. Run repeatedly until no more found.

    http://www.majorgeeks.com/ATF_Cleaner_d4949.html

    KCleaner ftp://ftp2.kcsoftwares.com/kcsoftwa/files/kcleaner.exe (impressive temp cleaner, I like!)
    -------------------------------------------------------------------------------------
    The issues can and are likely found is in System Restore so do the below

    Start-Programs-Accessories-System Tools-Disk- System Restore and create a new Restore point. Name it "After cleanup at TechSpot".

    Then Start-Programs-Accessories-System Tools-Disk Cleanup
    Click OK to accept C:
    Select all Boxes
    Then click More Options
    Here click System Restore and OK to "Are you sure" and the OK to Run.

    As this runs it clears all but the most recent Restore Point but it does one other thing that can contain infested files and a huge amount of disk space.

    It clears what is known as Shadow copies which are used by specialized back up programs.

    This is if you have the Volume Shadow Copy running which is the default.
    -------------------------------------------------------------------------------------

    Every 2 weeks or so run mbam and sas until clean They take a while so leave scanning while you are sleeping working or watching TV. If not done under the gun they can be schedules not to interfere with computer time.

    If they find something they can not clean then get back to us.

    Additionally run CCleaner.

    I have been using ThreatFire for more than a year, it just went from ver 3 to ver 4.

    It was designed to co-exist with other Virus scanners.

    Additionally it uses totally different process to protect. While conventional Virus scanners work from definitions ThreatFire works on recognizing Virus/Malware activity. It's like looking at it with 2 sets of eyes and from a different angle.

    Look at http://www.javacoolsoftware.com/spywareblaster.html

    Run SpyBot ocassionally and use the Immunize function.
    http://www.safer-networking.org/en/download/

    Install Hostman and allow it to disable DNS Client and select all offered Host files and the Update
    Hostman http://www.abelhadigital.com/2008/07...-released.html

    A Disk scan and Defrag are in order.

    Right so i've processed everything in the last post apart from running disk cleanup and defrag, which ill do overnight.

    The only problem was when using KCleaner, it got stuck on MSN Messenger for a long time. I used to use msn alot so there are probably alot of files hiding somewhere. You wouldnt happen to know where these are and i will just delete them manually. If not no worries.

    Anyway thanks for the help and ill be keeping a better check on protecting my computer from now on.

    You might try KCleaner in Safe Mode after the Scan and Defrag!
