Trojan found; Internet Explorer shuts down

Discussion in 'Virus Information' started by =?Utf-8?B?TW9uaWNh?=, May 10, 2006.

  1. I keep getting a warning that my homepage is trying to be changed and
    Internet Explorer keeps shutting down and then it gives me an error message.
    I have Norton and ran my anti-virus protection but it didn't find anything.
    But when I ran Spybot it found the "Cool Web Search" trojan on my computer.
    I deleted all the files and manually went through the registry to delete any
    traces left from this. Now although I can get online for a couple minutes and
    the error message does not come up anymore, Internet Explorer still keeps
    shutting down. I installed the CW Shredder available on the web and it found
    one version of the coolwebsearch trojan and deleted it. But like I said, I am
    still having the same problem with Internet Explorer shutting down. I ran
    Ad-aware and it did not find anything else. I re-ran Spybot and it came up
    clean too. I am going to try and perform a clean boot later this afternoon
    but was hoping maybe someone could tell me what else I can do? I'm not sure
    if a clean boot will help solve my problem. Does anyone have any suggestions?
    Thanks.

  2. From analyzing your problem, I believe your problem is more so non-viral
    malware; however, the Comprehensive Malware Instructions on the Detailed
    Malware Removal page of my website: www.stopmalware.tk should clean your
    computer of at least 95% of all malware.

    If you are using any version of Sun Java that is prior to JRE Version 5.0,
    then you are strongly urged to remove any/all versions that are prior to JRE
    Version 5.0. There are vulnerabilities in them and they are actively being exploited.
    It is possible that is how you got infected with malware.

    Therefore, it is highly suggested that if there are any prior versions of Sun Java
    to Version 5 on the PC that they be removed and Sun Java JRE Version 5.0 Update 6
    be installed ASAP.

    Simple check, look under...
    C:\Program Files\Java

    The only folder under that folder should be the latest version...

    C:\Program Files\Java\jre1.5.0_06


    http://www.java.com/en/download/manual.jsp



    For non-viral malware...

    Please download, install and update the following software...

    * Ad-aware SE v1.06
    http://www.lavasoft.de/
    http://www.lavasoftusa.com/
    http://www.lavasoft.de/ms/index.htm

    * SpyBot Search and Destroy v1.4
    http://security.kolla.de/
    http://www.safer-networking.org/microsoft.en.html

    * SuperAntiSpyware
    http://www.superantispyware.com/superantispywarefreevspro.html

    After the software is updated, I suggest scanning the system in Safe Mode.

    I also suggest downloading, installing and updating BHODemon for any Browser Helper Objects
    that may be on the PC.

    * BHODemon

    http://www.majorgeeks.com/downloadget.php?id=3550&file=11&evp=245a87539eea8ed6904332b4b8b8442d

    For viral malware...

    * Download MULTI_AV.EXE from the URL --
    http://www.ik-cs.com/programs/virtools/Multi_AV.exe

    To use this utility, perform the following...
    Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
    Choose; Unzip
    Choose; Close

    Execute; C:\AV-CLS\StartMenu.BAT
    { or Double-click on 'Start Menu' in C:\AV-CLS }

    NOTE: You may have to disable your software FireWall or allow WGET.EXE to go through your
    FireWall to allow it to download the needed AV vendor related files.

    C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
    This will bring up the initial menu of choices and should be executed in Normal Mode.
    This way all the components can be downloaded from each AV vendor's web site.
    The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the PC.

    You can choose to go to each menu item and just download the needed files or you can
    download the files and perform a scan in Normal Mode. Once you have downloaded the files
    needed for each scanner you want to use, you should reboot the PC into Safe Mode [F8 key
    during boot] and re-run the menu again and choose which scanner you want to run in Safe
    Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

    When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive PDF help
    file. http://www.ik-cs.com/multi-av.htm

  4. Hi David

    Thank you for responding to my post. It took me a couple days to get through
    all the steps you suggested since some of those scans took over 3 hours.
    I updated the Java as I did have a previous version.
    Ad-Aware found Alexa and deleted it.
    Spybot keeps finding something called a DSO Exploit. Even after I delete it,
    it keeps coming back. I ran the Multi-AV as you suggested and ran all of the
    scanners. Kaspersky was the only one that found anything. The log shows that
    it found 7 viruses and deleted 6.
    Internet Explorer still continues to shut down when I open it up though. Do
    you still think this is malware related? Would re-installing Internet
    Explorer help in this case?
    Thanks again for your help.

    DSO Explouit is an old False Positive declarartion by SpyBot S&D. Either you have an OLD
    version (prior to v1.4) or an old signature set.

    Updating to SpyBot S&D v1.4 and the latest signature files should correct this False
    Positive.

    Please copy and paste the Kaspersky log or extract the pertinent lines from the log showing
    the "infected" files found and paste that into your reply.

  6. I have sent an email to your email address listed on your profile.
    I tried to post the info from the log in this reply but it exceeded the
    character limit. Thanks for your help.
