  1. Hello,
    Yesterday my AVG detected a Trojan and then healed it, but it keeps coming back. Free adul pop-ups started to show and messages that my system is infected. I did a clean up with ewido anti-spyware, but when I ran a scan with AVG, the trojan is still there. Here I post my hijachthis report. Thank you very much.
    Best Regards Maria Bazhlekova

    Hello and welcome to Techspot.

    A lot of trojans etc, hide in your system restore points. No antivirus programme can kill anything in them. With that in mind, please follow the instructions below.

    Boot into safe mode. See how HERE. http://www.bleepingcomputer.com/forums/tutorial61.html

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

    Now run your antivirus programme again and delete whatever it finds.

    Reboot into normal mode and turn system restore back on.

    Then, go HERE and follow the instructions exactly.

    Then, post a fresh HJT log as a .txt attachment into this thread, only after doing the above.

    Regards Howard :wave: :wave:

    hjt report

    Hello,
    I rebooted the computer in safe mode and started AVG, AD Spyware and Search and Destroy and fixed everything it found. So these are both my HJL and EWIDO reports. Now the pop-ups and alerts are gone, but I'm not sure if the viruses are away.
    Thank you for the help!
    Best Regards, Maria

    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.
