Hi, and thanks in advance. I was taking a look at this laptop over the weekend, but ended up running out of time to work on it and am going back tomorrow. Since I've not found any good leads, I'm going to try and reconstruct my posts from that night and see if anyone here can help.
Ok, so this laptop shows a good internet connection and IP, but launching internet explorer results in eternal page loading. This happens with both wi-fi and ethernet connectivity.
Tried ipconfig/flushdns and no dice. This is a home network, and my laptop hasn't had any trouble with his router.
The internet was working, then after CCleaner was run (not by me), this problem appeared. Restoring the registry to pre-CCleaner was unhelpful.
Trying Firefox and Opera resulted in the same issue.
Any ideas?

Can you ping an ip and get a response?
Probably stupid but.... Did you pay the internet bill?
This machine can get a good ping and tracert for google, yahoo, etc. DNS settings are unchanged from 'automatic'.
Command line:
If that doesn't work, power cycle the devices in the following order:
1. Cable/DSL Modem 2. Router 3. Computer
The only network problem that wasn't able to solve was when the NIC was bad in the computer.
I'd check that.
edit: your tcp/ip stack could also be broken. I've seen that happen. You can try uninstalling all clients, services and protocols from the network connection then uninstalling the nic from the device manager. Reboot, let it PnP and setup the connection again. I'd download the drivers for the nic just in case.
Try "telnet www.google.com 80" and see if it will connect you. You can also try starting in Safe Mode w/ Networking to see if that produces different results. It sounds like a funky Windows/software issue.
e: Pacbowl that sounds like my plan of attack for tomorrow. Run MBAM, then try uninstalling/reinstalling the network devices.
You could also try in command prompt / powershell :
The first one will reset your WinSock catalog and the second will reset the TCP/IP stack.
Also, make sure that you do not have any proxies set.
[Control Panel]->[Internet Options]->[Connections tab]->[LAN Settings]
Uncheck all three check boxes.
If none of these work, try and burn and boot a Linux LiveCD (e.g. Ubuntu if you are not familiar with Linux) and see if you can browse the internet.
Sorry - needs to be done in a command prompt and without the quotes.
After pulling my hair out thinking it was a networking issue, I tried Opera and Chrome and it fired right up - which proved to me it was a hijack that was smart enough to look for the most commonly used browsers.
Can you browse to a website via IP address instead of dns name?
Who is your ISP, check out if they have a listing of DNS servers that you can plug in manually into your settings.
check your HOSTS file as well, see if there is any bullshit that shouldnt be there.
I tried inputting Google's IP addy, but had the same results. What should I be looking for in the HOSTS file?
WildEEP I tried FF and Opera after the problem manifested, to no avail.
If you don't have a packet sniffer, you can try this to get a clearer picture of what the PC's doing.

Reset the TCP/IP stack with "netsh int ip reset c:\resetlog.txt", restarted the computer, and no dice. Installing Malware Bytes now.
just means that behind the router you're static as 192.168.0/1.whatever
Death to CCleaner!
