Default Laptop Refuses to Connect to the Internet

Hey guys. So a customer brought in a Laptop that we had to remove viruses on. We did so, not the internet isn't working. I looked at it, and the Microsoft Teredo Tunneling Adapter in the Device Manager has the triangular sign with the exclamation point (!) on the inside of it. Also, the IPv6 will not connect at all. How can I fix this?

why would you use IPv6?
You have properly tried installing new drivers. right?
if yes, undo whatever you have done during the virus hunt by using system restore.
That's an easy and fast fix that works most of the time

A virus could have affected the drivers for the network adapters. Uninstall them and re-download them. Also run basic diags such as pinging google and see if the windows network troubleshooter helps..

Alright, I went in, and the closest restore point was after we did the virus removal. What do I do now?

What happens if you delete the adapter then follow the answer from here to get it back?

Yeah, we tried the second one, and that didn't work. I already tried reinstalling the drivers and that was a no go, because we couldn't find the drivers for it!

We just tried using a USB Dongle to connect to the internet, and that did not help at all
