    Hi tinamara and welcome to techspot.

    You have posted your question in the wrong forums. I shall PM a mod to move your post to our Security and the Web forums.

    Meanwhile, please do the following.

    You may wish to copy and paste these instructions on notepad for easier reference later.

    Boot into safe mode under your normal user name. See how HERE

    Next turn on "Show all files and folders, including hidden and system". See how HERE

    Go to start > run and type services.msc. Press the enter key.
    Search for the following services(if there) double click to select stop if they are running. Set the startup type to disabled. Click apply/ok for each service you disable.

    ATI Video Driver Controls

    Open your task manager by pressing holding ctrl, alt and pressing del. Alternatively, use ctrl + shift + esc. Go to the processes tab, and end the following processes, if found:

    sys.exe
    LT86FA.EXE


    After that, run HijackThis and fix the following entries, if found (do this by placing a tick in the check boxes beside these entries and clicking "Fix checked"):

    O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)

    O4 - HKLM\..\Run: [ATI Video Driver Controls] sys.exe

    O4 - HKLM\..\RunServices: [ATI Video Driver Controls] sys.exe

    O4 - HKCU\..\Run: [ATI Video Driver Controls] sys.exe

    O4 - HKCU\..\RunServices: [ATI Video Driver Controls] sys.exe

    O4 - HKUS\S-1-5-18\..\Run: [ATI Video Driver Controls] sys.exe (User 'SYSTEM')

    O4 - HKUS\S-1-5-18\..\RunServices: [ATI Video Driver Controls] sys.exe (User 'SYSTEM')

    O4 - HKUS\.DEFAULT\..\RunServices: [ATI Video Driver Controls] sys.exe (User 'Default user')

    Fix all the O17 entries if you do not recognise the domain to be your ISP

    Close HJT.


    Navigate in Windows Explorer and delete the following files and folders in bold.
    C:\WINDOWS\TEMP\LT86FA.EXE
    C:\WINDOWS\system32\sys.exe

    Reboot into normal mode and rehide your protected OS files.

    Thereafter, please post a fresh HJT, ComboFix and AVG Antispyware logs from normal mode as an attachment into this thread.


    Regards,
    Your friendly Momok =)

    Hi,

    It seems that your system may not fully clean yet. I would need to read a ComboFix log to be fully sure.

    I suspect there may be some hidden processes lurking, as some random name .exe keeps appearing in your C:\Windows\Temp folder.

    I need you to run ComboFix in normal mode, as well as CCleaner, AVG Antirootkit and AVG Antispyware via the instructions in this thread.

    After you are done with the instructions, please post fresh ComboFix, AVG Antispyware and HijackThis logs from normal mode as attachments to this thread.

    Please let me know the results of the Anti Rootkit scan too.

    Regards,
    Your friendly Momok =)

    Your HijackThis log looks OK.

    However, it's hard to tell if it's actually clean with the computer in safe mode.

    Please post a fresh HijackThis log from normal mode.

    Regards :)

    I have merged your new thread into this one. Please don`t start any more new threads for this. Thanks.

    Your system is still infected. Please do the following.

    1. Please download The Avenger by Swandog46 from HERE. Save it to your Desktop and extract it.

    2. Download the attached avengerscript.txt and save it to your desktop

    Note: the above code was created specifically for this user. If you are not this user, do NOT follow these directions as they could damage the workings of your system.

    3. Now, start The Avenger program by double clicking on its icon on your desktop.

    Under "Script file to execute" choose "Load script from file".
    Now click on the folder icon which will open a new window titled "open Script File"
    navigate to the file you have just downloaded, click on it and press open
    Now click on the Green Light to begin execution of the script
    Answer "Yes" twice when prompted.

    4. The Avenger will automatically do the following:

    It will Restart your computer. ( In cases where the code to execute contains "Drivers to Unload", The Avenger will actually restart your system twice.)
    On reboot, it will briefly open a black command window on your desktop, this is normal.
    After the restart, it creates a log file that should open with the results of Avenger’s actions. This log file will be located at C:\avenger.txt
    The Avenger will also have backed up all the files, etc., that you asked it to delete, and will have zipped them and moved the zip archives to C:\avenger\backup.zip.

    5. Please attach the content of c:\avenger.txt into your reply, as well as fresh HJT, Combofix and AVG Antispyware logs.

    Regards Howard :)

    Everything looks fine there.

    Turn off system restore.(XP/ME only) See how HERE.

    Now, turn system restore back on. This will have deleted all your old restore points and any nasties that are in them. It will also have created a new, clean restore point.

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

    Regards Howard :)
