I have been battling a trojan dropper. AVG would find it remove it, but then a little while later it would show up again. Prior to posting this I did the following: downloaded HJT and ran it, scanned the log through an auto-analyzer and removed two nasties. Then, I updated AVG and scanned again. Than ran Malware bytes. The log is pasted below. Then I ran HJT again and pasted the log below. Please let me know if you see any other nasties that I need to remove.

Hi,

Download ComboFix from one of these locations:

Link 1

Link 2

* IMPORTANT !!! Save ComboFix.exe to your Desktop

  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. Here is a guide on how to disable them:
    Click me
    If you can't disable them then just continue on.
  • Double click on ComboFix.exe & follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.
