Computer cannot get DHCP address and if assigned valid static IP it still can't use network

The computer (HP laptop, Vista 64bit Home Premium SP1) had/has viruses. To remove viruses, I took out drive and hooked up to another computer and used 2 different scanners to remove viruses. I then put the drive back in the laptop and now I am trying to run Spybot/SUPERAntiSpyware and other programs on the laptop but I can't get the network to work. Both the wired and wireless network adapters will not get an IP address using DHCP. If I statically assign a valid IP, Gateway, and DNS server the little icon in the system tray switches to the globe but I cannot ping or resolve DNS addresses.

"Do you have Norton 360 or any other Norton networky kind of program installed? If so, try disabling it and restarting. Try also toggling the Windows Firewall on or off to see if this has any effect.

Otherwise, try a quick scan for any corrupt system files (have your Vista installation media at the ready.) Click the Start button, type sfc /scannow and hit Enter. Once the box telling you its scanning disappears, restart and see if the problem is resolved. If you had an infestation that broke any system files, especially relating to networking, this may well do the trick.

Failing that, try a system restore back to a point before you picked up the nasties. I would put my money on this fixing it.

If you wanted to give it a go, there is a tutorial on doing a repair installation under Vista. I would personally skip that and go straight for the reinstall as you suggested. Viruses can get so deep into the system, affect so many system files and get so well hidden, sometimes it's less painful to just reinstall. Plus, you'll get a super speedy computer out of it (or at least super speedy as far as Vista goes... ;-)"

Has the HOSTS file been modified by the malware? That would create some network issues. Can you do tracert to a known host like www.cisco.com (72.163.4.161) and see where your packets fail?
