Trojan Horse

  1. I have been running Norton, AVG, Adaware and Spybot on my system. AVG is the only program picking up the trojan, but I cant seem to get it off of my system. I have my system restore off. It shows up as c:windows/system32/awtr.dll. Anyone with any suggestions? Im totally lost right now!

    the .dll has hooks in the registry that your virus scanner cannot remove. You need to find the regkeys that go with the .dll and remove them.

    Hello and welcome to Techspot.

    I have moved your thread to the correct forum.

    Go and read the Viruses/Spyware/Malware, 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:

    No offence, but if you have to ask that question then you would be better off following Howard's instructions as messing with your windows regestry can do serious harm to windows if you are not %100 sure of what you are doing!!!!

    If you`re that concerned at getting rid of that one file, do the following.

    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

    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 your need to enter into killbox.

    c:\windows\system32\awtr.dll

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

    In my experience, it`s unlikely that the above file is your only infection.

    Therefore, I strongly suggest you follow the instructions in the link I gave you.

    Regards Howard :)

    My computer still seems to be dragging now. Could it still be a virus somewhere?

    I`ve just looked at your HJT log again and although it`s clean, I can see a big problem. I didn`t notice before as I was looking for nasties lol.

    It appears you`re running three antivirus programmes, AVG/McAfee/Symantec-Norton. You`ve also got a bit of Panda antivirus running. This is why your computer is so slow. It`s definitely not recommended as it can cause serious conflicts.

    I advise you to keep AVG and uninstall McAfee, Symantec/Norton and Panda.

    Once you`ve done that, you`ll need to install a firewall programme. You can find links to a couple of free firewall programmes HERE.
