  1. Hey guys! First time poster, long time reader for solutions on these kind of problems...
    I am having problems removing both of these from my system. Did a full NAV scan in safe mode and tried using that Aproposfix app. Norton detects both trojans everytime I reboot my machine but they never show up in a system scan.

    Backdoor.Rustock.B is showing up as winsyst32.exe in
    C:\DOCUME~1\Troz\LOCALS~1\Temp\

    Hacktool.Rootkit is showing as iexplorre32.dll in
    C:\WINDOWS\

    The only thing that was looking kinda fishy in my HJT log file was O17 tcp/ip settings but when I delete it I can't access the internet until I restore my reg backup. Any Suggestions?

    Hello and welcome to Techspot.

    First, go HERE and follow the instructions exactly.

    Then, go and read the Trojan Pakes and other nasties preliminary removal instructions. Follow all the instructions exactly.

    Post fresh HJT and AVG Antispyware logs as attachments into this thread, only after doing the above.


    Regards Howard :wave: :wave:

    Followed the instructions and ran a AVG in safe mode. Came up with 2 new trojans which it deleted. Ran a HJT and saved log. Rebooted and avg detected a virus as well as norton. Here are the logs...

    You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.

    Turn off system restore.(XP/ME only) See how here.> http://www.bleepingcomputer.com/forums/tutorial56.html

    Boot into safe mode, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how here.> http://www.bleepingcomputer.com/forums/tutorial61.html

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how here.> http://www.bleepingcomputer.com/forums/tutorial62.html

    Click start/run and type services.msc into the run box and press the enter key.

    When the window appears, maximise it. Double click on the following services(if there) and select stop if they are running. Set the startup type to disabled. Click apply/ok for each service you disable.

    LUYPXE

    Close the services window.

    Open your task manager, by holding down the ctrl and alt keys and pressing the delete key.

    Click on the processes tab and end process for(if there).

    LUYPXE.exe

    Close task manager.

    Run HJT with no other programmes open(except notepad). Click the scan button. Have HJT fix the following, by placing a tick in the little box next to(if there).

    O23 - Service: LUYPXE - Sysinternals - www.sysinternals.com - C:\DOCUME~1\Troz\LOCALS~1\Temp\LUYPXE.exe

    Click on the fix checked button.

    Close HJT.

    Locate and delete the following bold files and/or directories(if there).

    C:\DOCUME~1\Troz\LOCALS~1\Temp\LUYPXE.exe

    Reboot into normal mode, turn system restore back on and rehide your protected OS files.

    I need to see an AVG Antispyware log. You can find instructions for AVG Antispyware HERE.

    Regards Howard :)
