[list]Now is the time to remove one of those two antivirus.

Multiple Antivirus Programs

You are running more than 1 Antivirus program!

AV: avast! Antivirus
AV: Microsoft Security Essentials

Running - more than one - antivirus program is not recommended because:
[*]They can conflict with each other.
[*]Report the other antivirus software as malicious.
[*]Antivirus programs use an enormous amount of computer’s resources… actively scanning your computer.
[*]Can cause your computer to become unstable…run slowly and even, in rare cases, BSOD crash…etc
I strongly suggest you uninstall one of them. Which one, is your decision.


Then I want once more round with Combofix.

Delete Combofix, download fresh copy of Combofix.

Open notepad and copy/paste the text present inside the code box below:



KillAll::

ClearJavaCache:: 

DirLook::
c:\users\Ben\AppData\Roaming\QuickScan
c:\users\Ben\AppData\Roaming\mjusbsp


Save this as CFScript.txt

Close all browser windows and refering to the picture above.

Referring to the screenshot above, drag CFScript.txt into ComboFix.exe.
