  1. Please help me as I have picked up the Vundo trojan. My computer has slowed way down and I will get random popups constantly. McAfee identifies that the trojan is there and says that it removed it but it keeps coming back. I have done the 8 steps requested and attached are my logs. How malicious is the Vundo trojan? I appreciate all of your help.

    Reboot then run both MBAM and SAS again as they will likely find more!

    Post these new logs.

    Ok looking good but some more work to do

    Run HJT Scan only, select and Fix the below entries
    R3 - URLSearchHook: (no name) - - (no file)
    O1 - Hosts: 82.98.231.89 browser-security.microsoft.com
    O1 - Hosts: 82.98.231.89 best-click-scanner.info
    O1 - Hosts: 82.98.231.89 antivirus-xp-pro-2009.com
    O1 - Hosts: 82.98.231.89 microsoft.infosecuritycenter.com
    O1 - Hosts: 82.98.231.89 microsoft.softwaresecurityhelp.com
    O1 - Hosts: 82.98.231.89 onlinenotifyq.net

    O1 - Hosts: 82.98.231.89 microsoft.browser-security-center.com

    Then do the below..

    Download ComboFix

    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.

    Install Recovery Console if connected to the Internet!

    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.
    =========================================

    Download SDFix 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.

    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.

    Last thing after all above a new HJT log.

    O23 - Service: McAfee Framework Service (McAfeeFramework) - Unknown owner - C:\Program Files\McAfee\Common Framework\FrameworkService.exe (file missing)

    Before we proceed with my closing how is computer running?

    The computer seems to be running fine, actually much faster than before I picked up Vundo. Thank you for all your help. I never would have been able to do it on my own.

    Glad to help do the below to finish up!

    Thread Closing-------------------------------------------------------------------

    Some of these tools update so often they require downloading again later if needed. But keep and run MBAM and SAS to maintain.

    Remove ComboFix
    Start-Run
    type
    combofix /u
    Hit enter or click OK.

    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.

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

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

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

    -------------------------------------------------------------------------------------
    Run CCleaner http://www.ccleaner.com/download/builds (get SLIM at bottom no Yahoo toolbar)
    Run twice or more on Cleanup temps, then on left click Registry then Scan for issues also repeat till clean.

    Run ATF-Cleaner http://majorgeeks.com/ATF_Cleaner_d4949.html Temp and Registry, repeatedly until no more found.

    KCleaner ftp://ftp2.kcsoftwares.com/kcsoftwa/files/kcleaner.exe
    Fantastic cleaner. (When installing uncheck Relevant Knowledge do not install)
    -------------------------------------------------------------------------------------
    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.
    -------------------------------------------------------------------------------------
    ERUNT
    Add a redundent Reg backup, get and install ERUNT let it add itself to startup and do a backup on install check all boxes.

    ERUNT http://www.larshederer.homepage.t-online.de/erunt/
    Yes! Even if you use system restore and other backups Registry and Images.
    -------------------------------------------------------------------------------------

    Every two 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 scheduled not to interfere with computer time.

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

    Additionally run CCleaner. ATF-Cleaner and KCleaner.
    ----------------------------------------------------------------------------------------
    I have been using ThreatFire for more than a year, it just went from ver 3 to ver 4.

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

    Additionally it uses a 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.

    It works like some Firewalls do to learn what is good/bad.

    After install it will ask you about everything that could be a security issue. For example the first time you run IE or FireFox it will prompt you. You would answer to approve and remember the setting. From then on no more prompts about IE or FireFox unless the exe changes like in an update.

    As it queries you about the prompt to help you determine to approve or not you can google it with one click.

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

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

    I highly reccomend Hostman: Hostman http://majorgeeks.com/HostsMan_d4592.html

    Download install run and allow it to disable DNS Client and select all Host files and then Update and install all host files.

    A Disk Scan (chkdsk) and Defrag are in order.
