Error Code 80072EFE RRS feed

  • Question

  • Hello - I've attempted a couple of the solutions posted in these forums.

    I successfully deleted the Catroot2 folder twice, however it seems to keep coming back.

    So I figured, maybe I'll run a virus scan through Malwarebytes's AntiMalware software.  btw - i did these steps several times and still ended up with the same result.

    After running the scan, delete the catroot2 folder.  Restart the computer. 

    I was hoping upon restarting the computer, I can update windows, hoping that the update would prevent the virus from recurring.  Unfortunately, the same 80072EFE was generated whenever I try to search for new updates.  I've browsed through the forums but many of the links provided no longer exist.

    I was curious to install the following:

    support.kaspersky.com/downloads/utils/tdsskiller.exe .

    but was afraid that this might actually pose additional probems for me.  I'm hesitant to install another program on the computer.  Anyone?  Please help. . . .

    These are the viruses scanned:

    Programs\Startup\isirag.exe (Spyware.Passwords.XGen)

    Local\Temp\7928.tmp (Trojan.Dropper.Gen) 

    tmp30bf961c\google-toolbar.exe (Trojan.Hiloti)

    tmpd7892d4f\google-toolbar.exe (Trojan.Hiloti

    System32\cyis.koo (Trojan.Dropper.Gen)

    Windows\System32\config\systemprofile\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\51\30f9b733-26c9f415 (Spyware.Passwords.XGen)

  • Hi,


    The error code 80072EFE can be caused by one of the following factors:


    1. The computer was attacked by viruses.

    2. Some background programs, such as antivirus programs or firewalls (for example: CA Firewall, McAfee, Zone Alarm, etc.), block access to the Windows Update.


    Please take the following suggestions to test this issue:


    Suggestion 1: Remove Trojan or viruses via your antivirus program


    If there is no other antivirus program installed, you may use Online Scan:

    1. Please click "
    Windows Vista and Windows 7 edition".  Please click "Full Service Scan" and follow the instructions on the screen to scan for viruses on the computer.

    2. When the scan is finished, please restart the computer.(you may also use the Microsoft Security Essentials.)


    Suggestion 2: Disable firewalls or other Internet browser programs that can affect the Internet connection


    This issue could be caused by third party applications. Let's first try disabling or uninstalling any third party security applications you may have installed on the computer. Please be advised that this is for troubleshooting purposes only. Once we have resolved the issue, the applications should be re-enabled or reinstalled immediately. If the third party security application is determined to be the cause, please contact the vendor for assistance.


    You may have a different security application not listed below that could also be causing the issue. Even if the firewall has been running for some time without any problems, new updates may create issues. Here is a list of the most common security applications:


    Symantec Norton

    CA Firewall


    Zone Alarm

    Panda Security


    Sophos Antivirus

    Comodo Firewall


    Webroot Spy Sweeper




    Once the third party security applications have been disabled or removed, please access the Windows Update web site again. If you encounter problems disabling these programs, we recommend completely uninstalling them while troubleshooting. Before uninstalling any application, please enable your Windows Firewall and ensure that you have the CDs or files needed to re-install the program.


    After that, please go to check updates in the Clean Boot.


    If the issue persists, please assist me in collecting the following information in order to provide more effective troubleshooting steps.
