Huge problems whit Internett (plz help)

[Concker]

Hello, im having some serius problems whit my internett connection at the moment,
It all started whit my old setup. i had an asus m2n-e sli motherboard and installed windows and all worked perfectly, but some days later when i start my machine i get the message: unable to connect to the internett, but it connects to my rutermodem, but i just cant get no internett connection, ive god so tired of this that i build a new rig for windows 7, and formated everything, and reinstalled windows 7 on my new systems, works like a dream, then now about 6 days later i get the same problem!

I just cant understand what the problem is, we got 3 machines here, all running w7 and connected to same ruter, and im the only one whit this problem, i also got a friend of mine whit the same motherboard and he got no problems at all?

My system:

Motherboard: Asus Maximus ii formula p45 Socket 775
Cpu: Intel Q9950
GFX: Gainward 8800gt 1gb
Soundboard: Xfi Supreme FX
Network controller: Marvell yukon 88E8056
Ram: 4gb of Kingstone 1066mhz DDR2
os: Windows 7, Ultimate 64bit

So the only way i can get internett on this machine now is to go to device manager and delete the nettwork addapter, then find new hardware and then it works untill i restart my pc?

Also What ive done is:

Updating to the newest network controller driver, and the one before that whitout luck. then i run the microsoft security essential virus scan, and it only found the trojan: Trojan:win32/Orsam!rts, I quarantine this one whitout luck, same problem

I realy cant get whats wrong, my best guess is a virus, but get it on a new machine right after fresh install? and the virus controll cant find nothing. i also run the latest windows updates whitout luck.

So it cant be the motherboard since ive changed it, and same problem (and yes i have formated the pc completly and freshly installed w7)

List of other problems installed on my pc:

Firefox
Quake4
Winamp
Photoshop cs3
sony veges 9.0
mirc (for use whit gaming, havent clicked any links on it)
spotify (music program)
MSN
Ventrilo
Mumble
windows mail
Utorrent (tho i havent downloaded a single file after reinstall)
Magicdisk (for mounting iso files)
Office 2007
Steam
Xfire

Thats all the programs i have installed atm, and i havent been into any suspicius sites, just normal online newspapers sites her in norway witch i know is secure.
so i realy dont think its virus either.

Any 1 got any ides? thanks.

Uninstall, not just deactivate your Anti Virus and see what happens. Until you find one that you may prefer use Microsoft Essentials

read more carefully plz, im using microsoft essential and i dont think it is virus, it seems more like the network dont find the ip or something, but dont know, but im 100% sure its not virus or problems whit a firewall because it worked perfectly untill yesterday.
