Internet Explorer Connection & Windows Defender

I removed a virus with malwarebytes. All is gone, but although I can connect to the internet wirelessly and wired, I am not able to connect to the internet. I receive the message "Internet Explorer Cannot Display the Webpage." All other computers on the same network are working. When going to network sharing center / wireless connections / TCP/IPv4 / properties, obtain IP address automatically is checked in both places. When I go to device manager / network adapters, isatap has a yellow triangle and !. I have tried to go to cmd, run as administrator (it comes up as c:\Windows\system32>) and type in netsh int ip reset c:\resetlog.txt and it did not work. It says "Reseting Echo Request, Failed." Reseting Global, ok!, Resting Interface, Ok

In addition to the above, every time I turn the computer on I continue to get the Windows Defender message, "Application failed to initialize: 0x80070006. The handle is invalid."

Any help would be greatly appreciated. Thanks.
