Cannot get a network connection on any adapters on a previously working Vista laptop

I have a Dell Laptop with a Broadcom Ethernet NIC as well as an onboard wireless NIC.  It was working previously.  The user had a malware infection which was cleaned with Malwarebytes.  After cleaning it the network stopped connecting.  On the Broadcom I have a solid Orange LED on one side and a flashing yellow LED on the other.  The wireless takes longer than usual to connect, says it's failed to connect but when I look at it, it says Limited connectivity.  I can also see it connected on the WAP.

When I diagnose either NIC I get:

 "The Network Adapter "[whichever adapter I'm dianosing is here]" is experiencing driver or hardware related issues.  
 and
make sure your Internet Protocol Bindings are correct...

I've disabled IPv6.  I've reinstalled the latest drivers.  I've reset Winsock and the IP protocol with the netSH command.   I shut off the firewall and AV software as well as Windows Defender.  Dell was ZERO help.  Any ideas?

It's likely that you didn't get everything. I'd suggest you download and run Spybot Search & Destroy. Of course if you want to cut right to the chase. Just get the network adapter drivers from Dell, reinstall them and see if that gets you up and running. If that doesn't work then you still have active infections. I've written some guides on fighting spyware and malware that I intend to publish here as I get the chance. If you still, after installing the network drivers cannot get a connection I'll give you a link to a guide that might help. Well... here: http://www.codeproject.com/KB/work/antispyware.aspx

If you need it go read that. It will help immensely.

Delete any exsiting Profiles you have in your Wireless configuration utility.

Run sfc /scannow from run command

Rawinninx9 - Rand Spybot S&D it found nothing.  Drivers were already downloaded and installed (see original post)

Dariusq - Ran SFC.  Received the message:  "Windows Resoure Protection found corrupt files but was unable to fix some of them.  Details are included in the CBS.log...."

Also, ran ComboFix which found and repaired a few issues but still didn't fix the network.  Re-ran reset of WinSock and IP.  Re-ran SFC /scannnow.   Still no luck.

Unfortunately I don't have another Vista PC around.  Lots of Windows 7.

B is only because it's a "last resort" solution.  (reinstall)
