REMOVAL OF P2P PROGRAMS

There are signs of one or more P2P (Peer to Peer) File Sharing Programs on your computer.

As long as you are using any form of P2P networking to download files, you can anticipate malware infestations.

References citing the risk of using P2P programs:

I strongly recommend that you uninstall:

BitTorrent
Vuze

You have not disabled the programs. They will be run when needed.

WIN = key with the Microsoft logo on top

rmcog,
I don't find your CPU on the list of supported CPUs for your motherboard.

I suggest you go to the Gigabyte site and not some 3rd party site:
GIGABYTE TECHNOLOGY Socket AM3 - NVIDIA GeForce 7025 / nForce 630a - GA-M68MT-S2 (rev. 1.3)

Since you have refused to go to the gigabyte site to learn about your product, then I'm wishing you success in your independent endeavors.
