Hi,
I see that you are using
uTorrent, a p2p file sharing program. I would like to warn you that the nature of P2P filesharing is so that even if one is using a "clean" program, many of the files downloaded from non-documented sources have the potential of being infected. Even if the program you use is not infected itself, it will still bring malware into your system because more than half of all files available for download from peer-to-peer networks have been deliberately infected with some form of malware. I recommend that you remove it from your system via Add/Remove Programs in Control Panel.
======================================
Please delete
Avenger from your desktop, or wherever you downloaded it. It's a dangerous tool to use casually. It can cause serious damage to your system if not used properly.
