Hello and welcome to TSF.

I have a backdoor virus and have both avg and Avanquest VirusScanner Pro running.

First item to address is that it's a bad idea to have more than one antivirus installed and running. Multiple antivirus programs can bog down your system, interfere with each other, and may even cause crashes.

Please remove all but one of them using the Add/Remove Programs in the Control Panel.

==============================

And yes, one or more of the identified infections is a backdoor trojan.

This type of infection allows hackers to remotely control your computer, log keystrokes, steal critical system information, and download and execute files without your knowledge.

If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Please read this: How Do I Handle Possible Identify Theft, Internet Fraud, and CC Fraud?

========================

If you wish to attempt to clean the computer, please download ComboFix from one of these locations:

Link 1
Link 2
Link 3

* 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
  
• 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.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Click on Yes, to continue scanning for malware.

# Your desktop may go blank. This is normal. It will return when ComboFix is done. ComboFix may reboot your machine. This is normal.

Note:
Do not mouseclick combofix's window whilst it's running. That may cause it to stall.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.
-----------------------------------
Note: Please make sure that your AntiVirus and AntiSpyware applications are re-enabled. A reboot should have done this.
