    Hello and welcome to Techspot.

    This infection seems to be doing the rounds lately.

    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:

    Download the Pocket Killbox programme from HERE. Extract it but don`t run it yet.

    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

    Go to add remove programmes in your control panel and uninstall anything to do with(if there).

    ComcastToolbar

    Close control panel.

    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).

    uninstall.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).

    O2 - BHO: (no name) - {64582371-8B2A-A1C6-CE40-0A8E8EB54F78} - C:\WINDOWS\system32\yzwyatl.dll

    O2 - BHO: (no name) - {CFE9E8A8-38C0-4EF8-AEC2-5035EFE81030} - (no file)

    O2 - BHO: (no name) - {E3215F20-3212-11D6-9F8B-00D0B743919D} - (no file)

    O4 - HKLM\..\Run: [bhcfvfb.dll] C:\WINDOWS\system32\rundll32.exe C:\WINDOWS\system32\bhcfvfb.dll,gmzxdjg

    O11 - Options group: [INTERNATIONAL] International*

    O16 - DPF: {238F6F83-B8B4-11CF-8771-00A024541EE3} - http://a516.g.akamai.net/f/516/25175/7d/runaware.download.akamai.com/25175/citri x/wficat-no-eula.cab

    Click on the fix checked button.

    Close HJT.

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

    C:\Program Files\ComcastToolbar<Delete the entier folder.

    Run the killbox.exe file. When it loads type the full path to the file you would like to delete in the field and check the delete file on reboot button. press the Delete File button (looks like a red circle with a white X). It will prompt you to reboot, select no until you have finished inputting the files you want to delete, only then allow it to reboot and hopefully your files will now be deleted. If your computer doesn`t automatically restart, restart it manually.

    These are the filepaths you need to enter into killbox.

    C:\WINDOWS\system32\bhcfvfb.dll
    C:\WINDOWS\system32\yzwyatl.dll

    Once your system has rebooted, turn system restore back on and rehide your protected OS files.

    Please rename HijackThis.exe to HijackThis1991.exe and post a fresh HJT log.

    The reason I want you to rename HijackThis.exe, is because some malware can hide from HijackThis.exe.

    This is the HijackThis entry from your HJT log.

    C:\Program Files\hijackThis\HijackThis1991.exe\HijackThis.exe

    As you can see, you`re still actually running HijackThis.exe and not Hijackthis1991.exe.


    Regards Howard :)
