Please Help I'm Pulling My Hair Out

  1. Dear Experts

    Yesterday whilst browsing a few websites i accidently (i know LOL) saved and opened what NORTON described as a Download.Trojan and spent most of my day off from work trying to resolve the situation and eliminate the blasted thing. As you have probably gathered i'm no IT expert but always been interested in the technical and scientific aspects of all computing areas including coding. On this note i think i have eliminated most of the trojan files but there seems to be a few that remain as i keep getting a number of pop ups every hour or so.

    I have attached a print screen of one of the pop ups that my system has to put up with and another one i have described;

    It is a red and grey window that says 'Security system Waring"

    Alert Details
    File: C:\WINDOWS\wml.exe


    Click here to visit PC-Antispyware web site..

    There is also another similar one;

    System Integrity Scan Wizard
    Warning: Your ocmputer may have critical errors in Windows registry and file system!

    I must also point out that i also receive a pop up in the the right system tray which alerts the following

    To scan your computer for errors please click the 'Next' button below

    In addition an exclamation mark still appears in the bottom right system tray that says click here to fix problem (It is beginning to wind me up LOL)
    This might also be of help i have noticed in the manage add on area 2 dll files kdftlboerfg.dll & qvdntlmw.dll which i disabled.

    Hope this is enough information and really look forward to receiving some sort of help/advice that can help elimnate this pain in the backside and destroy it forever.

    Kind Regards

    Hi RendeZvous147, :wave:

    Im Kritius,

    I need you to follow all the steps HERE and then post back with the three requested logs as attachments
    • AVG antispyware
    • ComboFix
    • Hijackthis (step 15)

    Dont forget to make sure that AVG is set to quarantine the results, that HJT is the last step and to let us know the results of the antirootkit scan.

    If you have any questions then just ask.

    Good luck and welcome to techspot.

    P.S you're not going to get far with Norton

    Hi Joe Beard

    Many thanks for this additional information.
    What do you suggest I do as i am starting to have difficulties on my computer after a period of just pop ups.

    An installer registry log is not functioning
    My Norton Antivirus will not update
    I deleted the exe file you located qtkrkpqr.exe and the pop ups stopped.
    I could not locate the other exe file it seems to be hidden even after i have selected the show all files and folders.

    I have decided to just recover my computer using the VAIO recovery tool as ive burnt all my important files onto discs.

    Do you think this would be wise as once the computer has formatted itself will there be any trace of virus/trojan etc...

    Look forward to your comments and once again thanks for checking my attched log.

    try the shorter path first Restore a System Restore Point.

    the question is when did you LAST install something --
    pick a R.P. one day later

    Many many thanks for your time and help on this particular scenario.

    However i took the time out to save all my important files onto a number of DVDs in order for me to use the VAIO RECOVERY TOOL which i performed last night and the computer is back to normal.

    All i have to do now is transfer all the files i copied onto DVD and my system will be back to normal. Please note all my files that were sent onto DVd were on a partitioned drive away from the C:

    However i do have a question?

    As i have performed a system recovery what is the likelyhood that this damn pest otherwise known as Downloader is still present on the computer even though it states the computer will go back to the original factory settings?

    Once again many thanks for your help and i once again look forward to your response.

    I don't see any trace of the infection

    But to prevent future infections here are a few things I noticed

    Update your Java Runtime Environment
    • First try going to Start -> Control Panel -> double click Java
    • Select the Update Tab at the top of the Java console
    • Click the Check for Updates button at the bottom
    • If it finds the newer version (Java 6 Update 5) Follow the on screen instructions
    • After it installs the newest version Go back to Control Panel -> Add/remove programs
    • Uninstall any older versions of Java

    If for some reason you couldn't update through the above instructions.
    • Click the following link
      Java Runtime Environment 6 Update 5
    • The 4th option down is the one you want (click Download)
    • Check the box to agree to terms of service
    • Check the box for your operating system and click 'Download selected'at the bottom
    • After the install Go to Start-> Control Panel-> add/remove programs (Programs and features), and uninstall any old versions
    • Navigate to C:\programfiles\Java -> delete any subfolders except the jre1.6.0_05 folder

    You aren't running Firewall Software. Please download and install one of these first!

    Use a Firewall - It is very important that you use a Firewall on your computer. If you use the Windows Firewall you might think that's enough but it only controls inbound traffic. Simply using a Firewall in its default configuration can lower your risk greatly. Here are some firewalls which are free for personal use and most commonly used:
    Online Armor

    I recommend you keep
    1 anti virus program
    1 firewall
    Spybot S&D, Adaware 2007, and another anti-spyware of your choice (I like MBAM)
    keep them updated.

    You can also turn on tea timer in Spybot:
    • Click on Mode at the top and make sure that Advanced is checked
    • Expand the Tools tab in the left pane
    • Single click on the Resident Icon also in the left pane
    • check Resident "TeaTimer" (Protection of over-all system settings) Active
    • Close spybot

    Also under Tools you can double-click System Startup in the right pane and disable programs from running at startup. This will free up system resources. For example if you don't use MSN Messenger everytime you run your computer you can disable it, then when you want to use it you can launch it through Start -> all programs, or make a shortcut on the desktop for it. That way it doesn't use resources when you aren't using it. Don't disable any entries in green though.
