I am not one of the anti-virus experts here and I'm not sure you are completely clean, but as far as your network issues I can suggest you try Start->Run->sfc /scannow (have your OS disk handy, as it will probably ask for it). Once that is complete go into Start->Control Panel->System->Hardware->Device Manager, find the Network Adapters, select your LAN interface, and select Uninstall from the actions menu. Reboot and Windows should discover and reinstall the interface, restoring the links broken by the malware. If you use anything other that "Automatic" (i.e.DHCP) to get your IP and DNS entries you will have to restore them manually.
If one of the Anti-Malware guys offers suggestions on making sure your system is clean, pay attention. Usually when something is messing with the comm stack at this level it means something bad is under the covers.
