    Hello and welcome to Techspot.

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

    R3 - Default URLSearchHook is missing

    O9 - Extra button: (no name) - {CD67F990-D8E9-11d2-98FE-00C0F0318AFE} - (no file)

    O18 - Protocol: msnim - {828030A1-22C1-4009-854F-8E305202313F} - "C:\PROGRA~1\MSNMES~1\msgrapp.dll" (file missing)

    Click on the fix checked button.

    Close HJT.

    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:

    Your HJT log is clean.

    Assuming your system is running ok, I think we can say your problem is solved.

    If you have any further virus/spyware problems, please post in this thread.

    Regards Howard :)

    I had the lop.ah tojan horse pop-up again.
    and the computer has been working quite slower lately.
    what do you think could be the problem?

    The Trojan that infected my comuter.

    I sent you the log file I just made.

    this is the path to the trojan:
    C:\WINDOWS\pdsny1.dll

    Trojan horse Lop.AH

    I made a search for the file(after I checked "show hidden files and folders" in
    the Tools => options => view tab), but I didn't find it.

    what should I do?
    In your opinion.

    Thanks,
    Odada

    Your HJT log is clean.

    Download the Pocket Killbox programme from HERE.

    Extract it to your desktop.

    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


    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.

    This is the filepath you need to enter into Killbox.

    C:\WINDOWS\pdsny1.dll<make sure this is the proper filepath to the trojan.

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

    Let me know the outcome please.

    Regards Howard :)
