Viruses and worms

After the recent update, Avast always detects that there is a trojan when i just open the Firefox or Internet Explorer. I have tried to clean the trojan and even followed the Avast instruction as attachment 2. However, this problem has not been solved. Could anyone help me with this? Thanks a lot…

Hi I will need to move straight onto a stronger tool

Download and Install Combofix

Download ComboFix from one of the following locations:

Link 1
Link 2

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

IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

[*]Double click on ComboFix.exe & follow the prompts.
[*]Accept the disclaimer and allow to update if it asks

[*]When finished, it shall produce a log for you.
[*]Please include the C:\ComboFix.txt in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

I would post the combofix log as suggested by essexboy so that he can analyse it.

Yes please post the log as no automated tools get everything some things they just do not see
