Solution:
It is done Motherboard.
The motherboard includes most of the slots that we'll run into these days. It's a little unusual in that we don't often see motherboards which have both PCI-Express slots and an AGP slot. The best slot to use for video cards is the PCI-Express x16 slot. The next best is the AGP slot. The next best is a PCI-Express x1 slot but video cards which fit that slot are very hard to find as of late 2006. Some low-budget computers are sold with integrated video and have neither PCI-Express x16 slot or an AGP slot.
That would be what is known as Spyware, a common form of this is known as a "Trojan Horse". This type of malware is typically latched on and hidden within files, such as when downloading a pirated version of a song, game, art-work, etc...
Verify the network card configuration, as possible it’s due to misconfiguration and can be fixed by re-configure properly.
